The function, performance and accuracy of the electrical components used as well as mechanical design are decisive in determining the productivity and quality of the output from machines and systems.

What's more, the drive concept also has a significant influence on the life cycle costs of a machine.

When it comes to power density, direct drives are unsur-passed. They are therefore the ideal solution when maximum dynamics and accuracy are required. In contrast to conven-tional motors, direct drives are integrated in the machine and transmission elements such as gearing, leadscrews or toothed belts, which are standard features of other drive types, can be omitted. This arrangement ensures a high degree of control stiffness and thus a good dynamic response and excellent precision.

A further advantage is that direct drives take up far less space in the machine.

Siemens offers two series of torque motors for high-precision rotary axis applications. 1FW3 complete torque motors for direct mounting on the machine, and 1FW6 built-in torque motors for integration in the machine design.

When highly dynamic, highly precise linear axes are required, our 1FN3 and 1FN6 linear motors are the obvious choice.

Built-in motors in the 1PH2 and 1FE1 series are specially designed for application in machine tool spindles.

Due to the high level of integration of direct drives in the machine, special attention must be paid to certain aspects, for example, to storage and cooling, that are less important when using conventional rotary servo motors.

Siemens offers not only the right direct drive for every task, but also the necessary experience and advisory expertise for supporting the user in planning integration of the drive in his particular machine.

In addition to the standard motors described here, applica-tion-specific solutions can also be implemented on request.

1FN3 linear motor – synchronous linear motor with magnetic secondary section track

OverviewLinear motors are highly dynamic, high-precision motors for linear traversing motions. Accordingly, linear motors are the preferred motor type for use in applications with stringent requirements in terms of productivity and accuracy. By virtue of their design, however, linear motors are also extremely robust, wear-resistant motors which are easy to maintain. Siemens offers two different linear motor designs for different application classes.

1FN3 motors are synchronous linear motors with an energized primary section equipped with coils and a secondary section equipped with permanent magnets. The high power density of 1FN3 linear motors makes them particularly dynamic, pre-cise and compact. The motors are generally liquid-cooled, but can also operate with natural cooling when derating factors are applied and design measures taken to ensure effective heat dissipation.

1FN6 linear motors are also synchronous linear motors, but have a nonmagnetic secondary section. They are available as both naturally cooled and water-cooled variants. Due to their inexpensive secondary section, 1FN6 linear motors are espe-cially recommended for long traversing paths or for applica-tions where a magnetic secondary section track would not be desirable.

1FN6 linear motor – synchronous linear motor with nonmagnetic secondary section track

Operating principle The diagram on the right shows the typical design of a travers-ing axis driven by a linear motor.

The secondary section is fixed (bolted) in the machine. By mounting a number of secondary sections side by side, it is in principle possible to create an optional length of secondary section track. The primary section is mounted on a traversing slide which moves on guide rails above the secondary section track.

The current through the coils of the primary section is con-trolled in such a way as to produce a traveling magnetic field. This interacts with the secondary section to generate a feed-rate force which sets the traversing slide with the primary section in a linear motion.

A linear position measuring system is installed on the machine side alongside the secondary section track for sensing the cur-rent velocity and position.

In addition to this classic constellation, there is a wide variety of possible combinations of primary and secondary sections, for example, arrangements with fixed primary section and moving secondary section, configurations with multiple primary sections on one secondary section track as well as gantry configurations.

Our mechatronics specialists will be pleased to give advice on the best motor configuration for a specific application. For standard applications in production machines, our partner SKF Linear Motion stocks a fully assembled linear slide which is equipped with a naturally cooled model of our 1FN3 linear motor.

1FN3 and 1FN6 linear motors6

1FN3 and 1FN6 linear motors

Versions and options of 1FN3 linear motorsDifferent versions of the 1FN3 linear motor are available, depending on the application you have in mind.

The primary section version for continuous load is recom-mended for machine axes with constant acceleration changes (oscillating), with high process/weight forces or for operation without water cooling.

For application profiles requiring high forces and acceleration rates for brief periods, the peak load version of the primary section is the perfect option.

The primary sections are designed as standard for water cool-ing. However, with the appropriate system design, natural cooling is also possible in certain cases.

In order to keep heat transfer to a minimum in precision applications, as an option both the primary and the secondary sections can additionally be equipped with a precision cooler. An optional cover for the secondary section makes the motors extremely robust against mechanical influences.

Components and options of 1FN3 linear motors

Design of 1FN6 linear motorsThe 1FN6 linear motors comprise a primary section that is equipped with coils and permanent magnets and a nonmag-netic, toothed secondary section in which the intermediate spaces are filled.

Sliding blocks are located on the top which are used to fix the primary section to a moving slide fitted onto a guide rail. The secondary section has sliding blocks underneath with thread-ed holes which are used to bolt it onto the machine.

By mounting individual secondary sections side by side, it is possible to create an optional length of traversing path. The only restrictions that apply are due to the maximum permissi-ble cable lengths or the maximum lengths of the measuring systems to be selected by the customer. A linear position measuring system is installed on the machine side alongside the secondary section track for sensing the position and velocity.

1FN3 and 1FN6 linear motors 7

Possible configurations of linear motorsThe motors demonstrate extreme flexibility in terms of their possible configurations: The classic single-sided arrangement is used most frequently. Alternative options include the two-track configuration or the arrangement of several primary sections on one secondary section track. This increases the force density or relieves the load on the linear guide.

Single-sided arrangement

If several primary sections are mounted in a machine, they can be controlled by a variety of methods such as:■ By operating multiple primary sections on one converter

using one position measuring signal■ By splitting the position measuring signal among several

converters with one primary section each■ By a separate position measuring signal for each con-

verter with one primary section each.

The first two variants are the preferred options in cases where there is a rigid mechanical coupling between the primary sections. The last control variant allows the primary sections to move completely independently of one another.

Two primary sections on one secondary section track

Two-track arrangement (gantry)

System integrationLinear motors of the 1FN3 and 1FN6 series merge perfectly into the system landscape of the SINAMICS S120 drive system. Thanks to the plug connector mounted on the front, the pre-assembled power and signal cables mean that the drive is ready to use in the shortest time possible.

Torque motors – Direct drives for rotary axes 11

Torque motors – Direct drives for rotary axes

1FW3 complete torque motor 1FW6 built-in torque motor

OverviewTorque motors are direct drives for rotary axes with which pre-cision and force are required at relatively low speeds. Because their maintenance and space requirements are minimal, they are often used as an alternative to geared motors.Siemens offers two different motor types for these types of application. The 1FW3 torque motor is a complete torque motor which, mechanically speaking, needs only to be flange-mounted to the machine and the rotor connected to the machine shaft.1FW6 torque motors are built-in motors. The stator and rotor can be supplied as individual components and integrated directly in the machine. They are available with jacket cooling or an integrated cooling system.Built-in torque motors must be precisely integrated into the machine. Our mechatronics experts will be happy to advise and support you in finding the right arrangement for your application and with integration in the machine.Both motor types feature a large hollow bore. The motor can therefore be pushed onto the machine shaft. Alternatively, media or mechanical components can be guided through the cavity in the rotor.

Operating principleThe 1FW3 and 1FW6 torque motors are synchronous motors, which basically operate in a comparable manner to rotary syn-chronous servo motors. Consequently, the rotor is equipped with permanent magnets, and the stator contains the motor windings. The multi-pole design of the windings endows the motor with maximum torques at low speeds. For speed and position control, the 1FW3 motor has a built-in shaft encoder; this must be fitted to the machine for 1FW6 motors. The torque motors are water-cooled as standard in order to achieve a high power density. This cooling method also reduc-es the amount of heat transferred into the machine.

Benefits and characteristicsThanks to the large number of poles, and because mechanical transmission elements and the associated backlash and frictional losses are dispensed with, torque motors boast the following characteristics:■ High torque■ Excellent rotational accuracy■ High acceleration capability■ Space-saving design■ Low maintenance■ High efficiency

ApplicationsTorque motors are ideally suited to the precise operation of rotary axes when high torques are required.1FW6 built-in torque motors are used, for example, in machine tools for

■ rotary tables■ swivel axes■ fork heads■ rotary indexing tables■ tool turrets■ lathe spindles

1FW3 complete torque motors are used, for example, in pro-duction machines for■ main drives for extruders■ worms for injection molding machines■ roller drives for paper machines■ winders for packaging and paper machines■ handling and assembly systems

Built-in motors for spindles 15

Built-in motors for spindles

1PH2 built-in asynchronous motor

OverviewUsers who produce their own motor spindles can obtain the right built-in motor from Siemens. These motors are charac-terized by their compact design, ruggedness, superior preci-sion and accuracy.

Siemens offers three different types of built-in motors for motor spindles:■ The 1PH2 built-in asynchronous motor is employed as

a compact, standard built-in motor for lathe and grinding-wheel spindles with maximum speeds of up to 10,000 rpm.

■ The "High Torque" version of the 1FE1 motor is charac-terized by very high torques, and achieves peak speeds of 18,000 rpm.

■ The "High Speed" version of the 1FE1 motor is character-ized by very fast acceleration rates, and achieves peak speeds of 40,000 rpm.

Principle of operation, designThe 1PH2 motor is asynchronous. The rotor, which is the squirrel-cage type, and the stator, which is equipped with windings, are delivered as components, which the engineer combines to form a motor spindle that he then installs in the machine.

The same applies to 1FE1 motors. However, unlike the 1PH2 version, they are synchronous, with a rotor that is equipped with permanent magnets.

With all these motors, water cooling is used to dissipate the heat. The position is sensed by external encoders, and most commonly with a SIMAG H2 hollow shaft measuring system in the case of the 1PH2 motor.

1FE1 synchronous built-in motor

Benefits and characteristicsBecause mechanical power transmission elements (belts, gears) and the resulting backlash are dispensed with, built-in motors boast the following characteristics:■ Excellent quality of surface finish■ High acceleration capability■ High rigidity thanks to compact design■ Free of wear■ High efficiency

ApplicationsOur built-in motors are ideal for use in motor spindles for machine tools:■ 1PH2 motors for grinding-wheel and lathe spindles■ 1FE1 motors for lathe, grinding-wheel and milling

Mechatronic support for direct drives 19

Mechatronic support for direct drives

OverviewDirect drives demand new solutions in the mechanical design of motors and the selection of new system components. Traditional complete motors have a clearly defined interface to the machine. In contrast, direct drives in the form of built-in motors require the motor and encoder to be integrated mechanically into the machine. Specially trained consultants (mechatronic experts) are ready to provide you with the support you need in designing a direct drive.

Our "Mechatronic Support" service offers an additional bonus. Even while a machine is at the design stage, this service models and optimizes all the mechanical, electronic and infor-mation technology systems included in the design for their functionality within the overall drive before they are imple-mented for real. Mechatronic Support is thus the intelligent alternative to "trial and error". Innovative machine concepts are mutually compared, modified and optimized at the outset – a process which of course also takes account of your ideas for new mechatronic components.

During this phase, our Mechatronic Support specialists offer you a comprehensive range of services to ensure that you can achieve development objectives within specified require-ments.

Scope of servicesSupport during machine development, from conception to machine acceptance:■ Comparison and analysis of machine concepts with

regard to static and dynamic precision, control loop dynamics and rigidity

■ Mechatronic modeling and machine simulation (Finite Element methods)

■ Computer-aided optimization of machine structures■ Optimum dimensioning of all motor and control loop

components■ Commissioning and control loop optimization■ Analysis and optimization of existing tool and produc-

tion machines on site

How you benefit from our Mechatronic Support:■ Shorter development times – quicker to market■ Reliable achievement of development objectives■ Risk-free testing of innovative machine concepts■ Higher quality and productivity from the outset
