Abstract:

This paper investigates the accurate modeling of induction motor ball bearing faults using modified winding function method (MWFM). We show that the stator current spectrum can be calculated with the method, and the fault severity of a bearing fault can be quantified with the amplitude of the corresponding faulty current component.
