Abstract:
Although motors that use rare-earth permanent magnets typically exhibit high performance, high costs and concerns about the stability of raw material supplies can limit production. This paper proposes a permanent-magnet-assisted synchronous reluctance motor (PMASynRM) with ferrite magnets that do not use rare earth materials. The performance of the proposed PMASynRM is evaluated based on the 2-D finite element method and an experiment using a prototype machine. The motor parameters, torque, output power, and efficiency characteristics are discussed. The analysis and experimental results reveal that the proposed PMASynRM has an efficiency equivalent to that of conventional rare-earth permanent magnet synchronous motors used in EV/HEVs.
