  4. Abstract:
  5. This paper presents a detailed analysis of short circuit fault (SCF) in wound rotor (WR) resolvers. For this purpose, an analytical model based on winding function (WF) method is developed considering the stator and rotor windings fault, the severity of the fault, the phase of the stator faulty winding, and the tooth of shorted turns. The proposed model leads to a comprehensive understanding of the SCF behavior of WR resolvers and also leads to define proper fault detecting signatures. All the predictions are verified by time stepping finite element analysis as well as the experimental tests on two prototyped resolvers. IEEE
