Sinusoidal back EMF waveform is essential for smooth operation of the Permanent Magnet Synchronous Machine (PMSM). It plays a significant role in reducing torque ripple, mechanical vibrations, and noise. However, due to inherent design  asymmetries, designing a motor with perfect sinusoidal back EMF is a challenging task faced by motor designers.

Join this webinar to learn how to overcome design challenges using EMWorks 2D, with our leading motor design expert.

In this webinar, we will explore

  • the effect of back EMF harmonics on the torque ripple.
  • how to determine the magnet span for PMSM to achieve sinusoidal back EMF waveform with minimum distortion.
  • how to eliminate specific harmonics of back EMF using shorted pitch winding.
