Hi everyone,
I'm writing a thesis about PMSM (AC Permanent Magent motor ), in which I should control the regenerative energy during it's braking. I have been wodering for a week, how the Back-EMF of PMSM can be simulated in Simulink, but still can not find a solution. Can someone give me some advices for this matter. I'm very grateful for your help.

If you're using Permanent Magnet Machine from Simscape library, I think, it has backemf as output signal. If you're building the machine model by yourself, you need to calculate it based on the rotor position and machine parameters

Brother,I think you can find the relationships in the Back-EMF in PMSM and its stator phase current then get the waveform of PMSM's Back-EMF.
