Abstract

Permanent magnets made of rare earth materials are used in interior permanent magnet synchronous motors (IPMSMs), which are major component of hybrid electric vehicles. The recent remarkable increase in the cost of rare earth materials is a major concern. A switched reluctance motor (SRM) without permanent magnets is one of the possible alternatives. Two types of SRMs have been designed with different materials. The SRMs have been investigated full loading tests. This paper reports a comparison between experimental and analysis results for the SRMs. The efficiency of both SRMs can exceed 90%, and the output power can be in excess of 50 kW.
