Abstract
Examples described herein provide a computer-implemented method that includes receiving data from an electric motor of a vehicle, the electric motor comprising a stator and a rotor. The method further includes performing a motor health degradation analysis to determine whether a degradation of the electric motor has occurred. The method further includes performing a stator health degradation analysis to determine that a stator degradation has occurred. The method further includes performing a rotor health degradation analysis to determine that a rotor degradation has occurred. The method further includes implementing a corrective action for the vehicle e responsive to determining that the degradation of the electric motor has occurred and at least one of the stator degradation or the rotor degradation has occurred.
