Abstract: An eccentricity detection system includes: a vibration eccentricity module configured to determine a vibration eccentricity of the electric motor based on vibration of the electric motor measured during operation of the motor; an inductance eccentricity module configured to determine an inductance eccentricity of the electric motor based on an incremental inductance curve of the electric motor; and a fault module configured to indicate whether the electric motor includes an eccentricity fault based on both (a) the vibration eccentricity of the electric motor and (b) the inductance eccentricity of the electric motor.
