Question

PMSM Current waves

Hi. I used steval-ipm15b and nucleo-g431 to run a pmsm motor. when I see the current waves in the motor pilot or osciloscope, they are not sinus-shaped waves. can anyone help me what is the problem and what should I do?

Hello @soheil3041,

Can you share both current wave snapshots? 
Could you add also the motor characteristics and use case MC pilots commands?
