Hi,dumitru-daniel.popa

 

 

 

  I made some further changes to the model modified by Leon Thürnau to make it work with KV4. I removed the Simulink Data Type Conversion module for multiplication. However, it has problems in the motor model. From the waveform point of view, the measured currents of phase A, phase B and phase C are correct. I do not know why the speed and back EMF of the motor are always zero, and I can not find the reason. I have attached my model. I hope you can help me, thank you!
