What could be the cause of poor-shaped sinusoidal current in electric motor drive?
In a synchronous motor drive simscape model, I need to test the motor performance before adding speed or current controllers, so I supplied the PWM generator with input reference sinusoids, but it comes out that the output motor currents aren’t pure sinusoids! What could be the reason of that? Shouldn’t the output currents be Ok with these current settings? Or does the uncontrolled torque somehow affect the current? Or is it something with the filtering at the inverter side? I think I don’t have problems with the sampling time and switching frequency settings.In a synchronous motor drive simscape model, I need to test the motor performance before adding speed or current controllers, so I supplied the PWM generator with input reference sinusoids, but it comes out that the output motor currents aren’t pure sinusoids!
