  Hello everyone
  I am using EDT software to simulate a motor with no load excitation and get the back EMF waveform but I do not know how to analyze the FFT of back EMF waveform in EDT software. Can anyone help me find out how to do it ? and how to calculate total harmonic distortion (THD) in EDT.
  the figure below that the plot i want to plot after analysis FFT of back EMF
  
  thank you so much

  Hello,
  You could get the FFT plot by:
  For THD calculation, please refer to #2055853 - Total harmonic distortion (THD) calculation in Maxwell (ansys.com)
