摘要: Permanent-magnet (PM) synchronous motor (PMSM) with rare-earth PMs is most popular for automotive applications because of its excellent performance such as high power density, torque and efficiency. However, the have problems cost limited supply material. Therefore, electric motors less or no are required in vehicle (EV) hybrid (HEV) applications. This paper proposes examines a PM-assisted reluctance (PMASynRM) ferrite magnets that has competitive density efficiency PMSM employed HEV. The PMASynRM designed taking into account irreversible demagnetization mechanical strength. prototype been manufactured, several performances torque, output power, losses, evaluated. Furthermore, high-power estimated based on experimental results PMASynRM, possibility application proposed to EV HEV discussed.
