Abstract

Owing to the use of the Permanent Magnet Synchronous Motor (PMSM) widely in Electrical Vehicles (EVs), the mandatory existence of rotor angle sensor in its control algorithm, higher reliability of the resolver than the other instance, and eventually, the significant effect of resolver errors on the system stability, comparing the reliability of two winding configurations in resolver is regarded analytically and numerically in the following study. Firstly, the employed assessment model is defined. Subsequently, it is necessary to investigate the failure modes in the resolver thoroughly. Among the methods used to assess reliability, the Markov model is chosen for the reliability analysis. Finally, by using an experimentally verified Finite Element (FE) resolver model, the faulty conditions in the Variable Turn Overlapping Winding (VTOW) and Constant Turn Non-Overlapping Winding (CTNOW) configurations of the Variable Reluctance (VR) resolver are investigated. The accuracy degradation of the resolver under faulty conditions is used as the reliability criteria to define the reliability state of the resolver.
