motor is drawing more current than expected

[hashiR]

Hello all,

I’m using NUCLEO F302R8 and IHM08M1 for motor control. While the motor runs, it gradually heats up to around 85°C and draws more current than its rated value in no-load conditions.

while using the IHM07M1, the motor's heating seems normal, but the board temperature rises significantly.

What could be causing this issue?

I don't know anything about the IHM08M1. But I have configured BLDC speedcontrollers for RC motors in the past. Once I had a motor getting really hot. It was the setting of the number of poles. I don't know why this had to be configured, but it made a huge difference. It must have impacted the timing or waveform and lead to current flowing when there shouldn't be current, leading to heating of the windings instead of providing torque to the motor.
Have you measured the output voltage and current with an oscilloscope? You can compare it with the output of the IHM07M1.
