Modelling and Comparative Analysis of Torque Profile of Six Phase and Three Phase Synchronous Reluctance Motor for Electric Vehicle Applications

This paper entails with the modelling of three phase and six phase synchronous reluctance motor in d-q reference frame. A comparison of the average output torque and torque ripple of three phase and six phase synchronous reluctance motor is done. The three and six phase synchronous reluctance motors are modelled and simulated in ANSYS MAXWELL and the results are compared. The six phase winding is retrofitted on the same stator of the three phase motor. A detailed analysis of the improvements in performance when the stator winding is made six phase is presented in this work. The six phase synchronous reluctance motor is observed to have high torque and low torque ripple which makes it a convenient choice for electric vehicle applications. The simulation results are encouraging and the experimental validation of the six phase and three phase machines is underway.
