Benefits of FOC:

• Best energy efficiency even during transient operation, due to optimal current angle

• Responsive speed control to load variations, due to direct and decoupled control of

electromagnetic torque and flux

• Precise position controldue to direct and decoupled control of electromagnetic torque

and flux;

• Acoustical noise reduction due to sinusoidal waveforms / optimized control

• STM32 MC SDK advantageAutomatic code generation, single/dual motor

ST’s Solution cover

all conditions

Fans, FW IP1. sensorless initial angle detection (IAD)

• An ST sensorless algorithm, to detect initial rotor angle

• Before the motor is started, the function is able to measure the initial rotor position

• in few millisecond,

• with an angle accuracy of +/- 30 electrical degrees, same resolution of Hall Sensors

• Then the startup procedure is automatically configured to set the best initial direction

• avoiding a backward rotation and maximizing the torque generated

• The advantages of the IAD function are:

• Successful startup rate

• Quick acceleration

• The IAD function is implemented on both 1shunt and 3shunt topologies

• The IAD function doesn’t need additional HW, and it’s compatible with

STM32 and STSPIN32 series

• An ST FOC in module to reduce acoustic noise

• Working on the Park reference frame, it generates a 6th harmonic of the main motor electrical

• 3-phase BLDC motor compressor with inverter solution is becoming the new market trend, vs the traditional

single phase induction motor.

• Architecture: motor drive electronics can go in separated board near the compressor or combined in one.

• Actually, there’s no difference for what about the MC portion, the ST solution fits in all the 3 of them.

• Sensorless method accuracy:

• FOC frequency = 16kHz (62.5us)

• observed angle error (accuracy) is ± 34 us

• -> accuracy can’t be better, given the FOC rate

• Sensorless method precision: average

value centered with real angle

Current regulation:

• Not sensibly affected, given the 12%

bus voltage ripple shown in the capture

• The following graphic reports for

each test the average Δ(iqs*)

obtained in the ten sets of

measurements

• Unbalance weight resolution can reach

to 200g

• Total weight resolution can reach to

500g(unbalance weight < 500g)

• Due to counterweight are not

standard(considering contact surface

size) ,as total weight becomes bigger

and bigger, resolution will decrease, so

total weight of this test only reach to

8000 grams

• Fast Response : Quick Startup to full speed based on Sensorless FOC control;

• Traditional Active Braking Strategy: Voltage surge of Vbus is out of Control, the max voltage surge will

reach 35Volts when motor braking from full speed; the braking time period from full speed to 300RPM is

440ms

• Voltage surge Controllable braking strategy: the braking time period from full speed to 0RPM is 530ms,

Controlled Voltage surge of Vbus reachs 30Volts (it could be set by FW freely)

• Complete HW + FW package tailored for suction motors in vacuum cleaners:

• HW is based on STSPIN32F0/A + 6x STD140N6F7 MOSFETs

(STEVAL-SPIN3201 is a good starting point; V supply = 8-45 V, I out = 15 Arms )

• FW is FOC sensorless in 2 shunts configuration; 1 extra optional shunt can be used for power measurement

HW configuration example

• This solution is able to reach the rotation speed of up to 100k – 130k RPM on single pole pair

motors (it has been tested and proved on several motors from real customer cases), constant

power mode so at to handle different working conditions of the air inlet
