Testing of the demonstration board

The overall test of the demonstration board was performed on a motor bench with applied

testing PMSM motor. Parameter lists of the used testing motor are below.

Motor parameters:

●

Maximal motor power: 300 W

●

4-pole pairs

●

Ls = 16.5 mH; Rs = 8

●

Ke = 36 V

●

Nominal speed: 2400 rpm (160 Hz)

The STMicroelectronics released “STM32 FOC firmware library v3.0” was customized to be

compatible with demonstration board STEVAL-IHM036V1. All related parameters of the

motor were included in the source code via “ST Motor Control Workbench” application (see

www.st.com/internet/com/SOFTWARE_RESOURCES/TOOL/CONFIGURATION_UTILITY/

motorcontrol_workbench.zip).

Test conditions:

●

Sensorless sinusoidal field-oriented control

●

Supply voltage 230 VAC; frequency 50 Hz

●

Ambient temperature: 25 °C

●

PWM switching frequency: 16 kHz

●

Testing for output electrical power: 25 W, 50 W, 75 W and 95 W.

The duration of the tests was around 1 hour for each mentioned electrical output power.

Measured parameters were taken at the end of the each test condition when all parameters

had a stable value.
