I bought a STSPIN32F0 and i try to run this board with a BLDC Motor. But the first 3-4 seconds is working then stops. The same problem with me on this linkWhy does my BLDC motor stop during acceleration?


The first acceleration is very nice but then the motor is vibrating and gives speed feedback error. I have seen at faults monitor.


Sometimes when I changed the RPM scroll bar it was fixed but still not always.


I use this GUI --> STSW-SPIN3201 - STSPIN32F0 Filed Oriented Control (FOC) Firmware Example - STMicroelectronics - STMicroelectronics 



My BLDC motor features:

- 24V 

- 4000 RPM


- With Hall Sensor

- BLY172S-24V-4000

This is motor link and this is motor datasheet.


Why does not this system work?


Please help me.
