We're having following issue with our motor control:The motor is running fine, however one can hear irregular "hickups" in the regulated speed.We did some tracing and found that the IqREF value has a significant jump up (~20A) and then back down afte...

I'd like to make our application more aggressive so that it can keep its speed constant under different loads.The speed regulator seems to be dialled in pretty good as it follows our setpoint perfectly fine.However, when I load the motor, the current...

[Basic Info]We're currently having issues with our custom board.It is based on the G431RB in FOC and 3-Shunt mode, with a DRV8323RS as the gate drive and for amplifying and attenuating the current measurement.The motor is a low-inductance (8.1µH) hig...

It has a higher priority than the timer (which it really doesn't need, I agree). I'll see about changing the priorities.In the meantime, we increased the filters on the hall signals, and it seems like the glitch is actually gone now.It wasn't possibl...

@GMA We managed to trace the issue back to the Hall speed measurement.I added some code inside hall_speed_pos_fdbk.c to write the values captured by the timer into a buffer.Now when I run the motor in torque mode at a constant speed, I stop updating ...

The hardware is a custom one running on a G431RBT, loosely based on the STEVAL-ESC001, with a DRV8323RS as the gate driver and for current sense conditioning.

Looks like the issue is related to the speed calculation.When I run the motor in torque mode, the motor runs perfectly fine, however the traced hall speed still shows the drops.HALL_SPEED drop while the motor is running perfectcly fine

At least using the MotorPilot tool in version 6.3.0 did not fix this issue.I'll wait for an updated version of it that hopefully implements the locales fix mentioned in the other thread.
