We decided to investigate two types of electrical machines for Hybrid Electric vehicle (HEV) applications, i.e. induction machine (IM) and permanent magnet assisted synchronous reluctance machine (PMA-SynRM) due to the sharp fluctuation of permanent magnet.
This paper makes a quantitative comparison between IM and PMA-SynRM for (HEV) application, in terms of electromagnetic and mechanical performance. The design process of IM is introduced, and for PMA-SynRM, a novel hybrid-PM assisted SynRM is proposed, which utilizes both ferrite and NdFeB PMs. The torque capability, torque/power-speed characteristics, torque ripple and efficiency map, are compared and discussed.
