Performance Analysis of PM Assisted Synchronous Reluctance Motor with Optimized Novel Design for Electric Vehicular Application

Abstract

PM motors exhibit superior performance characteristics required for electric vehicles with a high manufacturing cost due to the high requirement for PMs in rotor assembly. Although research is already done to find out a suitable candidate for non-PM motors, but still, they are not good choices for all the performance parameters. In this paper, authors have produced the new alternative against this as it is impossible to achieve high performance of the motor without the use of PMs for electric vehicles application. This paper presents a new design approach of PM assisted synchronous reluctance motor (PMASynRM) with the minimum usage of PMs in rotor flux barriers. Finite element method (FEM) is used to carry out work for analysis and evaluation purposes and required performance parameters are obtained and compared with benchmark models. Effects of changes in current and speed values on torque are carried out to study torque variations. A few design limitations are also analyzed and present.
