Abstract

The present disclosure relates to systems and methods for detecting a winding fault and the winding fault severity in a brushless direct current motor before motor failure. Methods for detecting a winding fault include time domain based sequence component analysis, fast Fourier transform analysis, or Hilbert analysis. Methods for detecting the severity of a winding fault include analysis of the standard deviation of real mean squared values determined using motor currents.
