INA - Drives & Mechatronics GmbH & Co.

oHG, a company of the Schaeffler Group,

specializes in linear and rotary direct

drives. These products are supplemented

by directly driven positioning systems

and related controllers and mechatronics

assemblies.

In addition to standard products, IDAM

also develops and produces customized

drive solutions.

Due to the increasing demands in terms

of dynamic performance, precision and

cost reduction, direct drives are be com -

ing increasingly more popular in modern

machinery and equipment.

IDAM has developed a standard series of highly efficient rotary motors that are

shown in this catalog. With this standard motor series as a starting point,

customer specific, customized motors can be developed and produced in low or

high volume.

The Perfect Drive for Every Application

The direct connection between motor

and accelerated mass increases dyna -

mic and static rigidity, reduces elasticity

and therefore enables an extremely

high level of positioning performance.

Direct drives are non-wearing, as a

result of which maintenance and

operat ing costs can be reduced whilst

simultaneously increasing availability.

In the industries of machine tools and

production machinery, automation,

productronics/semicon, measuring

technology and medical technology,

teams at IDAM have been developing

direct drives and complex drive systems

since 1990.

The development of the direct drives

and the positioning systems is effi -

ciently supported by the integration

of models and simulations.

IDAM employs a state-of-the-art quality

management system. At IDAM, quality

management is a dynamic process

which is examined on a daily basis and

is thus continuously improved. IDAM is

certified according to standard DIN EN

ISO 9001:2008.

Advantages of Rotary Direct Drives

Increases dynamic capacity

1. No conversion of motion form

• With a direct drive motor system,

there is no need for mechanical

linkage (gearbox, belt, etc.) bet-

ween the payload and the motor.

Thus there are no backlash, clea-

rance, friction, or elasticity prob-

lems. This makes for a much

stiffer and more easily controlled

system.

2. Multi-pole motor

• With a multi-pole design, IDAM

motors are capable of producing

very high torque. In addition, this

high torque can also be sustained

over a much greater speed range.

3. Thin, ring-shaped rotor

• Thanks to the thin, ring-shaped

design with a large, open inner

diameter, the motor is able to

produce high torque with a very

low rotor inertia. This allows for

very high motor acceleration

capabilities.

4. External rotor design option

• With an external rotor, the motor

can produce higher torque in a

smaller package than to an inter-

nal rotor motor.

5. Direct position measurement

• Thanks to the direct position mea-

surement of the feedback system

combined with a rigid mechanical

structure, highly accurate and

dynamic positioning is possible.

Reduces operating costs

1. Fewer components

• With a direct drive system, fewer

components are required. This al-

lows for easier assembly and align-

ment along with a substantial

reduction in maintenance. The

reduced number of components

enables a much more streamlined

supply chain. Also,with fewer com-

ponents, the modes of failure are

greatly reduced and thus greatly

increases the MTBF*.

2. No wear in the drive train

• Because motor power is transmit-

ted through an air gap and not

through mechanical components,

a direct drive motor system has an

extremely long life even with very

demanding duty cycles.

• This substantially reduces machine

down-time.

3. Reduces machine down-time

• In addition to the increased life and

reduced wear, the robustness of a

torque motor substantially reduces

machine down-time.

• With direct drive torque motors,

mechanical overload does not

damage the drive train as is the

case with geared motors.

Increases design flexibility

1. Hollow shaft

• With its large, open, inner diameter,

the hollow shaft design of a torque

motor allows for much greater design

flexibility. The hollow shaft allows

for tubing, fixtures, rotary unions and

wiring to travel up through the center

of the motor. This adds to the versati-

lity of design capabilities.

2. Installation of primary

• Thanks to the smaller space requi-

red, the primary can be easily inte-

grated into the machine design.

3. Reduce overall height

• Along with the large, open inner

diameter (hollow shaft), torque

motors are very compact in the axial

(height) direction relative to the tor-

que output.

Rotary frameless motors consist of a pri-

mary winding and a secondary winding.

The primary contains an active coil system

and the secondary has a permanent

magnet system.

The rotor can be either internal or exter-

nal (RI series and RE series) relative to

the primary (stator).

When current is supplied to the primary

(coil system), electromagnetic force pro-

duces torque in the secondary.

A guidance system (rolling element or air

bearing) is required to maintain a con-

sistent air gap between the primary and

the secondary. A measuring system is

also needed for determining rotor posi-

tion for motor commutation purposes.

The proper selection of these and other

essential motor system components is

based on many years of IDAM applica -

tion experience.

IDAM offers different motor designs for

different customer application require-

ments. Rotary, frameless motors mainly

differ in design by whether the motor is

slotted, slotless or ironless. These mo -

tors produce a high, consistent torque

across a wide range of speeds. The torque

output is determined by the active air

gap surface area between the primary

(stator) and the secondary (rotor).

The proper motor selection depends on

the required performance.

Unlike conventional motors, frameless

motors are classified according to the

required torque, not to the electrical

rating.

General Motor Characteristics – Efficiency

The motor constant km depends on the

ohmic resistance and hence on the

wind ing temperature of a motor.

The km shown in the motor data section

is specified for 25 °C. The diagram shows

the motor constant, km, derating factor

for different motor winding tempera -

tures.

Part 1 of the technical parameters (star-

ting on page 23) shows the power loss

(copper losses ) for different working

torque outputs ( Tp, Tpl, Tcw, Tc ).

Since torque motors generate a high

torque but do not deliver any mechani-

cal power, an efficiency specification is

not necessary.

Temperature [°C]

However, for an efficiency comparison,

the motor constant (km) can be used.

The motor constant can be expressed in

terms of the torque and the power loss,

at room temperature, over the linear,

full power range. When the motor heats

up, its efficiency reduces due to the

increase in winding resistance. See the

figure below.

Not included in the motor constant, km,

is iron (core) loss. Iron loss is depen-

dent on the motor frequency (rotational

speed), and has 2 components; hystere-

sis and eddy current. As the motor

speed increases, the iron loss must be

taken into account. The motor constant

km, refers only to the linear range of the

3-phase current.

Winding Options

The maximum rotational speed of a torque

motor depends mainly on the winding

configuration and the operating voltage

(UDCL).

As rotational speed increases, the Back

EMF voltage also increases, which count -

ers the input voltage. At the rotational

speed limits (nd, nlp, nlk, nln) shown in

the data sheets, the voltage require-

ment, with field oriented regulation,

corresponds to the intermediate circuit

voltage of the servo rectifier. Thereafter,

the rotational speed falls sharply.

For a given motor, the higher the DC link

voltage (UDCL) and the smaller the wind -

ing-dependent voltage (Back EMF) con-

stant (ku), the higher the maximum

achievable rotational speed.

Since voltage and torque constants

have a correlation, with higher rotary

speed requirements, the required cur-

rent increases at identic torque.

In part 2 of the technical parameters

(winding options), for every motor size

there are 3 standard winding options;

WL for low dynamic applications, WM

for medium dynamic applications and

WH for high dynamic applications. The

maximum rotational speed is then

shown for 2 fixed DC link voltage levels

(280 V and 600 V) and for 3 different

current levels (Ip, Icw and Ic).

The DC link voltage is proportional to

the rotational speed. From the torque-

current curve, one can see the resulting

torque given a specific motor current.

From the torque-speed curve, one can see

the when constant torque output begins

to decline relative to rotary speed.

8

Torque-Rotary Speed Characteristic

The speed limits nlp, nlw, nlc are calcu -

lat ed only with respect of winding spe -

cific parameters. If no field weakening

operation occurs due to speed induced

voltage drops the motor speed can be

maintained at any torque Tp, Tcw, Tc up

to the listed speed limits nlp, nlw, nlc.

The motor speed finally drops down to

zero, depending on the DC link voltage.

With higher speeds and torques the

motor produces additional (to copper

losses) frequency-dependent losses

(caused by eddy currents and cyclic

magnetization loss). With respect of

these thermal losses there is an additio-

nal speed limit in a range of ncr for a

continuous running (definition see glos-

sary).

Regulated motor movements require a

sufficient distance (0.8 times the rele-

vant maximum rotary speed) of the pos-

sible operating points from the dropping

range of the T(n)-characteristic.

A continuous characteristic means con-

tinuous operation. A dashed character -

istic means short-burst operation.

Torque vs. rotary speed

Winding specific speed limits are quiet

A continuous running of these motors

could be limited in a range around ncr

because of additional frequency-depen-

dent losses (see glossary). Then a furt-

her reduction of duty cycle or current is

required.

9

Torque-Current Characteristic

The linear characteristic ranges from the

origin (0,0) to the point (Tpl, Ipl), which is

characterized by the torque constant kT.

This is where the operating points of the

motor for uncooled operation (Tc, Ic) and

cooled operation (Tcw, Icw) are located.

The non-linearity of the M-I-character -

istic for larger currents results from the

saturation of the magnetic circuit of a

motor. The naturally curved part of the

characteristic is described in the data

sheet and in the diagram by the torque-

current points (Tp, Ip) and (Tu, Iu).

It has an inconstant and significant

smaller slope than kT.

The motor can be run briefly (matter

of seconds) up to the operating point

(Tp, Ip).

For acceleration processes this operating

point may be maximally used.

The limiting point (Tu, Iu) must not be

exceeded under any circumstances (not

even for a short time) because of the

danger of demagnetizing the permanent

magnets .

Thermal Motor Protection Cutout

Direct drives are often operated at their thermal capacity limit.

In addition, there can be overloads in the process which were not anticipated or

planned for. This can result in an additional current load which exceeds the per -

missible rated current. Therefore, the servo control for motors should, in general,

have an overload protection for checking the motor current. Here, the effective

value (square root of the mean) of the motor current may exceed the permissible

rated motor current for only a short while. This type of temperature monitoring is

very fast and reliable.

By default, IDAM motors have another additional thermal motor protection cutout

using PTC and KTY sensors, as well.

Monitoring circuit I

For protection of the motor, there are

three series-connected PTCs at the three

phase windings. In addition, there is a

KTY84-130 present in one phase in the

motor.

A PTC is a posistor (barretter). Its ther-

mal time constant in the built-in state

is below 5 s. In contrast to the KTY, its

resistance increases very steeply upon

the rated actuation temperature Tn

being exceeded, and increases to a

multiple of its value in the cold state.

This behavior results in a significant

change in the total resistance upon

three series-connecting PTC elements,

when only one of the elements exceeds

the actuation temperature of the Tn.

The use of the three sensors guarantees

a safe switch-off of the motor, even at a

standstill of the motor at asymmetric

phase load. A downstream common

commercial motor protection cutout

typically gets triggered between 1.5 to

3.5 kOhm.

Thus, up to a deviation of a few degrees,

the overtemperature of every winding is

acquired.

The triggering devices also react to an

extreme small resistance in the PTC cir-

cuit, which is normally an indication of

an error in the monitoring circuit.

In addition, they ensure a safe electro -

lytic isolation of the controller from the

sensors in the motor.

The motor protection triggering devices

are not a part of the standard supplied

kit. PTCs are not suitable for tempera -

ture measurements. The KTY should be

used if required.

If the customer so wishes, additional

monitor sensors can be integrated.

Standard connection, PTC and KTY

While the motor is at standstill, constant

currents flow through the windings, whose

magnitude depends on the respective

pole position. As a result, the motor is

not heated homogeneously, which can

lead to overheating of windings that are

not being monitored.

The PTC and KTY sensors have a basic

insulation to the motor. They are not suit-

able for direct connection to PELV/SELV

circuits, according to DIN EN 50178.

Monitoring circuit II

The KTY84-130 is a semiconductor resis-

tance with positive temperature coeffi-

cients. The measurement is carried out

depending on the motor type, with pos-

sible delay.

Electrical Connections

The standard cable connections of the

IDAM motors are axial in nature.

Their relative position to the radiator

connections is defined in the drawings.

The cable length from the motor output

is 1000 mm, or according to the cus -

tomer’s wishes. The cross-section of the

power connection cable is dependent

upon the rated motor current and docu-

mented in the catalog drawing. By de-

fault, the dimensioning is done on the

rated current Icw at Plw (cooled). The

motor cables are available from 4G0.75

mm2 onwards. The sensor cable 0.14

mm2 (d = 6.0 mm; rd = 45 mm; rs = 24

mm; m = 67 g/m) makes temperature

monitoring with PTC and KTY possible.

The axial cable outlets for the winding

From motor currents above 70 A

onwards, the cable outlets are matched

in an application-specific manner.

Positive direction of rotation of the

The electrically positive direction of

rotation corresponds, in the case of

all three-phase motors, to a right-

hand rotary field, i. e. the phase volt -

ages are induced in the sequence U,

V, W.

IDAM motors have this positive direc-

tion of rotation for rotor movement

circuit voltages up to 600 VDC

IDAM motors are tested, before shipping,

with differentiated high-voltage testing

methods and cast in vacuum.

IDAM motors are thus in agreement

with the EC directive 73/23/EWG and

the standards EN 50178, EN 60204.

Please pay attention, to the type-based

voltages with which the motors can be

rotated.

By means of extremely fast-switching

power semiconductors, which results in

high du/dt loads, far higher voltage

values than the actual inverter voltage

can exist at the motor terminals, espe -

cially in conjunction with longer con-

necting cables (from ca. 5 m) between

the motor and inverter. This puts a great

deal of stress on the motor insulation.

The du/dt values of the PWM-modules

should not be greater than 8 kV/μs.

The motor connecting cables should be

kept as short as possible.

For protecting the motors, an oscillo-

graphic measurement is necessary for

the actual configuration of the voltage,

existing at the motor, (PWM) across the

winding and against PE. The voltage

peaks that are present should not be

much greater than 1 kV.

From about 2 kV, gradual damage to the

insulation is expected.

IDAM engineers will support you in your

application for determining and reducing

excessively high voltages.

Overvoltages at the motor terminals under inverter operation

In this context, attention must be paid to the recommendations and projection

instructions of the controller manufacturers.

Cooling and the Cooling Circuits

The power loss that occurs during the

operation of the motor gets transferred

to the machine through the motor as -

semblies. This heat distribution through

convection, conduction, and radiation

can be purposefully influenced and con-

trolled by a constructive design of the

overall system.

The nominal torques of the motors are

approx. 50% higher with liquid cooling

than in uncooled operation. Depending

on the mounting space, accuracy require -

ments, and the necessity for cooling,

the motors should be designed and

integrated into the machine design.

In production machines with a high

rating or devices with very high dyna-

mics, and hence higher bearing loading,

it is preferable to work with cooling.

If a complete thermal de-coupling of the

motor and the machine is required (for

example, to avoid thermal deformation

of the machine construction in precision

machines), a precision cooling is addi-

tionally necessary. The actual cooling is

then called the main cooling or power

cooling.

The cooling of the motors is designed

as jacket cooling, which the user must

connect to the cooling circuit of a cool -

ing assembly. The cooling jacket is op-

tionally supplied as a part of the motor,

or is already an integral part of the ma-

chine construction for the customer.

The cooling medium goes from the inlet

to the outlet through holes in the cool -

ing fins at different levels.

The inlet and outlet can be connected

at will to the two connections. The flow

area is sealed to the outside with O-rings.

If water is used as the cooling medium,

additives that prevent corrosion and

biological deposits in the cooling circuit

should be used.

Power loss and lost heat

Apart from the power loss, which is described by the motor constant km additional

frequency-dependent losses occur in the motor, especially at high control frequen-

cies (in the range from 150 - 200 Hz). These losses contribute jointly to the heating

of the motor and the system assemblies.

At low control frequencies of the motors, the following applies: motors with a high

km produce, as compared to motors with a lower km, less power loss.

For the unrestricted thermal examination of the motor, bearing, and system assem-

blies, IDAM offers comprehensive thermal simulations.

Dependency of the Rating Data on the Supply Temperature

The continuous current Icw indicated in

the data sheet for water cooled opera-

tion can be achieved at a rated supply

temperature ϑnV of 25 °C. Higher supply

temperatures ϑV result in a reduction of

the cooling performance and therefore

also the nominal current. The reduced

continuous current Ic red can be calcu -

lated from the following quadratic equa-

tion:

This gives the following α(t)-diagram (α: angular acceleration) as well as the flow of

the torque required for the movement : T = J x α

(T: torque in Nm, J: mass moment of inertia in kgm2, α: angular acceleration in rad/s²).

A simple positioning takes place as a

positively accelerated movement with

subsequent braking (negative acceler -

ation, usually of the same amount as

positive acceleration; then applies ac cel-

eration time is equal to braking time).

A rhythm cycle is described in the ω(t)-

Diagram (ω: angular speed, t: time).

The diagram shows a forward-reverse

movement with pauses

(tM: movement time, tP: pause time).

According to the torque flow of the

desired rhythm cycle, the motor is

selected according to three criteria:

• maximum torque in the cycle M TP

according to data sheet

• effective torque in the cycle M Tc

(motor uncooled) or Tcw (water

cooling) according to data sheet

• maximum rotary speed in the cycle

Angular acceleration, maximum angular

speed and maximum rotary speed of a

positioning movement are calculated

with:

This equation is applied to the effective torque, if torques of the same magnitude act

in the rhythm cycle (mass moment of inertia and angular accelerations are constant).

Below the root sign appears: “sum of the movement times divided by the total of the

movement and pause times”. The denominator is thus the cycle time.

The positioning movement described takes place with a (theoretically) unending

jerk. If a jerk limit is programmed in the servo-inverter, the positioning times extend

accordingly. Constant positioning times require, in this case, greater accelerations.

NC indexing table applications

For indexing table applications, the

rotary speed n, the mass moment of

inertia J, the machining torque TM (in

movement) and Ts (standstill), as well,

as the angular accelerations α (S1-oper -

ation) and αmax (S6-operation) are

known mostly.

The machining times, i.e. the action

times of the torques change often.

Nonetheless, it is necessary to deter-

mine the effective torque in terms of

continuous torque and the maximum

torque as accurately as possible.

Example: Indexing table applications

Given values:

Tp = ( J αmax + TM + TF ) 1.4 = 2444 Nm. .

Calculation of the accelerations

The motor is selected according to the

torque Ts, as well, as the torques

in motion for S1 and S6 operation Tc

and Tp with factor of safety (stable

regulation):

To reach the rotary speed n at the end of the accelerated movement with a defined rotary speed-time function (exact ramp), the

motor must be selected according to the rotary speed for the torque Tp (with factor of safety):

This is for choosing the optimum motor

and for prevention of the maximum per-

missible winding temperature.

motor operation are included in the

torque calculation.

Availability/Selection of Sizes Series RI

RI torque motors are slotted, permanent

magnet-excited AC synchronous motors

with inside rotors.

The coils of the primary are placed in

grooves of the laminated ferrite core.

The secondary is an iron ring with per-

manent magnets fastened on it. This

series of motor models is optimized for

the maximum efficiency, which means:

maximum torque for available installa -

tion space with nominal rotary speed

and low power loss.

The usable torque is available linearly

across a very large area.

The definition of the torque characteris-

tics across the significant operating

points allows an advance design with

the help of our dimensioning examples.

The low torque variations allow the use

of the motors for precision applications.

• Highest power density in the smallest

installation space due to individual

components matched to one another

• Compact construction

• High dynamics and stiffness

• Highly efficient cooling

• Top values at synchronism due

to optimized running

• Practically free of maintenance

• Matched rotary speeds and windings

• As compared to the RI series, higher

torques with the same motor volume

• Tool changer

• Milling heads

• Swiveling axes

• Indexing table

Availability/Selection of Sizes Series RE

RE torque motors are slotted permanent

magnet-excited AC synchronous motors

with external running rotors.

The coils of the primary are placed in

slots of the laminated ferrite core. The

secondary is an iron ring with perma-

nent magnets fastened on it. This series

of motor models is optimized for the

maximum efficiency, which means:

maximum torque for the available instal-

lation space with nominal rotary speed

and low power loss.

The useful torque is available linearly

across a very wide range. The definition

of the torque characteristics across the

significant operating points allows an

advance design with the help of our

dimensioning examples. The low torque

variations allow the use of the motors

for precision applications.

Availability/Selection of Sizes Type RMK • RMF

RM motors can be built as flat-design variant (RMF) and as coaxial-design variant

(RMK). The RMK motors in turn can be provided with an inner rotor or with an ex -

ternal rotor. The motors, which are custom-built, are characterized by the following

parameters.

Diameter range: 0.07 m to 2.5 m

Torque range: 2 Nm to 15000 Nm

Speed range : Up to 15 m/s peripheral speed

RMK/RMF built-in motors are slotless,

iron-core permanent magnet-excited AC

synchronous motors. In slotless motors,

the coil windings are located in an air

gap between the magnetic ring and the

primary ring.

Slotless motors do not generate any

cogging forces. This outstanding proper-

ty of this motor series guarantees a very

uniform movement.

Through coreless windings and the

bigger air gap, these motors offer

the following special characteristics

in the application:

• very small electric time constant

• high dynamics in regulated operation

• high end-speed

• relatively low forces of attraction

• force output of about 2.5 to 3 N/cm²

per active air gap surface

• high flexibility in the construction

and in the diameter size, to be able to

fulfill customer-specific requirements.

RMF advantages

• Flat design

• Mean torque requirements in ma-

chines with less force or no forces

in the direction of movement

• Applications with high accuracy

• High synchronism

RMK/RMF applications

• In pivots

• In grinding machines

• In measurement machines

• In high-precision positioning axes

RMK advantages

• Coaxial design

• Mean torque requirements in ma-

chines with less force or no forces

Segment Motors

The IDAM built-in motors of all struc tur -

al shapes can also be made custom ized

in segment construction.

In contrast to the continuous rings of

the previously mentioned motors, the

primary and/or the secondary parts are

formed as segments in these motors.

This construction gives particular

advantages in motors with diameters

above 1260 mm or in case of special

geometric requirements.

• Motor segments (primaries) are

easy to manufacture.

• The torque can be scaled via the

number of segments.

• Very big diameters can be realized

economically.

• A redundant construction of torque

motors in segment construction is

thus possible.

• In case of movements less than 180°,

secondary parts can be segmented.

• Very suitable for small drives due to

the reduction of mass.

In combination with HSR magnet

systems, very large segment motors

are suitable for high-speed motors

with large diameters.

This construction has the following

advantages:

• Cost-effective segment construction

• Variation of the number of segments

• Implementation of large motors

• Redundant construction possible

• Reduction of the service costs

• Mass reduction.

89

Motors in Special Structural Shapes

Apart from the design of the motors as

built-in motors, for customized solu -

tions, function integrations - of machine

parts and motor parts - can be realized.

This allows the optimum integration in

the user’s machine.

The electromagnetic system of the

primary part can be integrated into the

housing of a revolving table or a machine

assembly, without loss of installation

space.

The magnet system of the secondary

part can be mounted directly on to the

shaft.

All technical data and dimensions can

be taken from the standard data sheets.

An intensive technical consultancy by

our engineers supports successful

implementation.

The increased design effort is already

economical even with small lot sizes.

In all cases, the advantages of the

direct drives can be utilized to the

advantage of the performance.

Saturation behavior

The torque increases with growing

effective current linearly at first, next,

the torque changes into the bent part,

and then increases in a flat, linear

fashion.

The bend results from the magnetic

saturation of the entire magnetic circuit.

(see diagram)

Diagram: Torque in relation to the current

Symbol Meaning Unit Explanation

Tu Ultimate torque Nm Ultimate torque at strong saturation of the magnetic circuit. When this value is

surpassed, for the heated motor (magnet temperature 80 °C), there is a danger

of demagnetization or thermal destruction within a short time. It must not be

used as a dimensioning quantity, but in case of short-circuit braking, attention

needs to be paid.

Tp Peak torque Nm Peak torque that can be generated for a short time (range of seconds) at Ip, which

is reached in the saturation range and at all operating temperatures with certainty.

At magnet temperatures up to 60 °C and in pulse operation, Tp can be increased

up to the value of Tu.

Tpl Peak torque, Nm Motor torque that can be reached for a short time (a few seconds), which is reached

linear range at the end of the linear full output range at Ipl. kT.

Tc Continuous Nm Motor rated torque at rated current Ic, at which the motor can be operated without

torque, uncooled cooling in a thermally stable manner, but gets heated thereby.

Tcw Continuous Nm Motor torque at Icw, which is available at rated operation with water cooling

torque, cooled as the continuous torque and at which a temperature drop of about 100 K is

obtained between the winding and the cooling system.

95


Ts Stall torque Nm Standstill torque at rest and at triggering frequency up to about 1 Hz, which

appears at a respective standstill current value, due to the non-uniform current

distribution in the individual motor phases.

Pl Power loss W The heat that is generated in the motor winding, which depends on the operating

method (current) and the ambient conditions (cooling) results in a time-dependent

temperature increase. In the upper full power range (at Tp), Pl is particularly high

because of the quadratic dependency on the current, whereas in the range of the

rated current, only a relatively low heating occurs.

Pl is calculated with the help of the motor constant km for a movement range with

the required torque T: Pl = (T/km)2

Plp Power loss W Peak power loss at Ip

Plpl Power loss W Peak power loss at Ipl

Plc Power loss W Power loss at Ic

Plw Power loss W Power loss at Icw

ϑ Winding °C Permissible winding temperature that is acquired by means of sensors with a cer-

temperature tain offset. The motor surface temperature that results depends on:

• the specific installation conditions (dimension of the machine construction)

• heat carrying conditions

• method of operation and hence the average power inflow

and can only be determined when this parameter is known.

Rth Thermical K/W Thermal resistance with which the temperature difference between winding - hous-

resistance ing or the cooling base can be determined at a certain power loss.

τel Electrical time ms Electrical time constant that describes the ratio L/R. The ratio is - independently

constant of the winding design – approximately constant. The effect on the control circuit

(closed loop) is less than the constant itself and depends on the degree of

voltage overstepping.

Δϑ

• km is a motor constant that expresses the relation between the generated torque

and the loss of power.

• It is temperature-dependent.

Thermal behavior

Because of a temperature increase,

the winding resistance increases, which

results in a drop in km.

At 130 °C, the motor constant gets

reduced to about 0.85 times the value

(see diagram).

At a constant current or torque, in the

motor that is already warmed up, as

compared to the motor that is still cold,

an increased power loss is generated

which results in an even higher motor

temperature.

km Motor constant Nm/√W Motor constant that expresses the relation between the generated torque and

the power loss, i. e. the efficiency. It depends on the temperature, and can only

be used in the static operation case, as well, as in the linear full output range of

the motor, e.g. in case of positioning processes with low speeds.

At 130 °C winding temperature, it gets reduced to about 0.85 times the value.

movement of the powerless motor, works in the direction of thrust and acts as the

torque ripple in operation.

ku Back EMF Vs/rad Voltage constant that is obtained in generator operation, and when multiplied

constant by the rotational speed gives the armature counter voltage resulting at the motor

terminals: UEMF = ku. n

nlp Limiting speed rpm Winding dependent limit speed without consideration of the dynamic heat losses

when peak current Ip without field weakening is applied.

After this point the motor torque decreases strongly (see diagram).

nlw Limiting speed rpm Winding dependent limit speed without consideration of the dynamic heat losses

when water cooled continuous current Icw without field weakening is applied.


nlc Limiting speed rpm Winding dependent limit speed without consideration of the dynamic heat losses

when air cooled continuous current Ic without field weakening is applied.


ncr Limiting speed rpm Limit speed under consideration of additional frequency dependent heat losses

(causes by eddy current and cyclic magnetization loss). A continuous, water cooled

operation at limit speed ncr is possible if the applied current is not exceeding

approx. 45% of the water cooled current Icw.

Speed ncr at water cooled current Icw can be operated at a duty-cycle of approx.

20%. In order to reach a duty cycle of 100% at current Icw, a speed reduction to

0.2 x ncr is necessary.

The torque (current) or the duty-cycle at speed ncr can be increased by use of a

special winding variant (Z winding).

Iu Ultimate current Arms Limiting current at which the magnetic circuit is strongly saturated. It is either

determined by the maximum current density in the winding or through starting

demagnetization danger at a magnet temperature of 80 °C (also see Tu).

Ip Peak current Arms Peak effective current that is in the range of iron saturation and is to be used as a

dimensioning quantity (also see Tp). In case of an only moderately hot rotor

(magnet temperature max. 60 °C) and pulse operation (max. 1 s), Ip can be in-

creased up to the limiting value Iu.

of the motor.

Icw Continuous Arms Effective rated current that is permissible in case of water cooling in continuous

current, cooled operation.

Is Stall current, Arms Effective standstill current at rest and at control frequencies up to about 1 Hz.

uncooled Due to the different current distribution in the motor phases, for preventing local

overheating, the motor current has to be reduced to this value, if no noticeable

movement takes place beyond a pole pair.
