FFT analysis of the back-EMF waveforms in EDT

    • phuonganhlovely.me

      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

      You could get the FFT plot by:

      For THD calculation, please refer to #2055853 - Total harmonic distortion (THD) calculation in Maxwell (ansys.com)
