Feasible Operating Regime of a Triple Three-Phase Synchronous Reluctance Motor using Field Analysis

Synchronous Reluctance Motors (SynRM) are attracting renewed interest in industrial and electric vehicle drive system applications. This paper employs electromagnetic field analysis in obtaining the torque and induced voltage equations for Triple Three-Phase (TTP) SynRM. The feasible operating regimes and the parameters for maximizing torque and power factor were identified by optimization. Finite Element Analysis (FEA) of different TTP windings configurations were conducted to verify the formulations. TTP winding configuration exhibiting low torque ripple was designed using an existing 5-KVA SynRM for application in motor drives systems.
