Simulation of a four phase switched reluctance motor including the effects of mutual coupling

ABSTRACT Switched reluctance motors are typically constructed such that the coupling between phases is relatively small compared to conventional induction and synchronous machines. While small, this coupling is not negligible and could have important influence on transfer of current between motor phases during both normal and abnormal conditions. This paper presents, for the first time, a coupled circuit model which allows for mutual coupling between motor phases. Comparison is made between simulation and test results and good correlation is obtained.
