Hall position / speed at low speed

[ANICO.1]

Dear MC SDK team,

We are experiencing oscillation at low speed in torque control with Hall sensors as main sensor.

In the picture attached, motor is mechanically locked and Iq current reference is set to 3A. As you can see in the picture Hall angle is oscillating. We did the same tests with electrical angle forced to a constatn value (0) to check current loop behaviour and there was no oscillations. Have you had similar troubles in other projects ?

Thanks in advance,

Best Regards,

Antoine

Happy new year MC SDK Team,

Have you any update on this question ?

Best regards,
