Description
Summary:Permanent magnet synchronous motor (PMSM) for EV/HEV pursues higher efficiency, higher power density, higher rotation speed and better NVH performance. To meet these requirements, an improved triangle rotor topology is presented. The new rotor topology is researched through comparing the performance with V shape rotor and traditional triangle shape rotor. The comparing results on air-gap flux density, key order radial forces, sound pressure, inductance, torque, anti- demagnetization capability and efficiency proved the advantage of the new rotor topology.
