Dear,

our custom motor with XMC1302 has acoustic noise during 390rpm.
There is no noise at 767rpm.

I attached U and V phase current wave.
These current at 390rpm are very dirty, far from sine wave.
Would you give me advice to improve the current ?

Jesus-san,

"PMSM Motor Control FOC Sensorless Example with uC Probe for XMC1300 series" is used as base. The URL is
https://www.infineon.com/dgdl/Infineon-PMSM_Motor_Control_FOC_Sensorless_Example_with_uC_Probe_for_X...

Now we use modified software to hire hall sensors.This software has customers property. I cannot open it at this forum.
Can I send it only for you by e-mail ?
