A Simple and Efficient Tool for Design Analysis of Synchronous Reluctance Motor

This paper presents an efficient tool for design analysis of a Synchronous Reluctance Motor (SynRM).The Winding Function Analysis (WFA) is used instead of the Finite Element Analysis (FEA).With WFA approach, parameters sensitivity analysis and the impact on the machine design can be evaluated very rapidly (under linear condition).The effect of rotor skewing, stator winding chording, pole arc and interpolar air-gap length on average torque and torque ripple is investigated.The results obtained by WFA are compared with those obtained by two-dimensional FEA.It is shown that the two methods give approximately the same results but require different computation time.
