Abstract
Wound field synchronous motors (WFSM) are being considered as an alternative to permanent magnet synchronous motors (PMSM) by leading electric vehicle (EV) manufacturers. However, the EV industry lacks experience with testing or failures in WFSMs such as shorted field winding turns and eccentricity. In this paper, a new concept for automated testing of WFSMs is proposed. The main idea is to use the dc-dc converter available for field control, as the test equipment for detecting rotor faults, whenever the EV is stopped. The change in the field winding impedance under optimal excitation conditions is used for detection and classification of field winding turn faults and eccentricity. An experimental study on a 20 kVA WFSM shows that the proposed method can provide automated detection and classification of WFSM rotor faults using existing hardware.
