Modifying back EMF waveform in a PMSM model

Hello,

I am trying to simulate a PMSM, which has a Quasi sinusoidal back-emf waveform. Is there any way I can define the back emf to be anything other than Sinusoidal/Trapezoidal?

Thanks in advance. Saurabh Kumar

Hello Saurabh This may require you to create a custom implementation of the PMSM machine with Simscape language.

Alternatively, use the FEM machine block where you can link magnetic flux with rotor angle.

Hope this helped a bit Juan
