Mathematical modeling and comprehensive analysis of induction assisted permanent magnet synchronous AC motor

Abstract

The induction assisted permanent magnet synchronous motor (IAPMSM) is a prospective choice for the electric and hybrid electric vehicle (EV/ HEV) drivetrain due to its lower losses, high efficiency and constant torque over a defined frequency range. This manuscript presents a part of an ongoing research project which is motivated towards building a prototype of an industrial 7.5 hp IAPMSM. Firstly, a new analytical approach to model the IAMPSM using rotor reference frame theory is proposed. The developed 7.5 hp IAPMSM model is then analyzed through calculated results and compared with the conventional model of the aluminum-rotor induction machine (ARIM) to elicit merits and demerits of the prototype being built. This paper aims to provide a comprehensive understanding of both the machines to serve as a guideline towards prototype development.
