Question

BLDC faults using Motor Control Library (FOC SDK v4.2)

Hello everybody,

I am trying to run a BLDC motor with the FOC SDK v4.2, using a STEVAL-IHM021V2 power stage and STMF32F303RE Nucleo board as MCU.

I set everything up with no trouble and connect the board to MC Workbench, but when I click start the motor shivers and stops. If I use Hall sensors, I receive a Speed Feeback fault, while sensorless I get a Start-up fault.

I believe they are both originated by the same issue: the low sides for U and W are always triggered simultaneously. I have revised the connections and they are not mutually connected. Did someone have the same problem? Any solutions/suggestions?

Thanks in advance,

Francisco

Hi Francisco. I have similar problem usinf STEVAL-IHM034V2 and a PMSM motor with sensorless control. I solve this changing the PID parameters, but I also not able to increase the motor speed.
