Design and Analysis of a V-Shaped Permanent Magnet Vernier Motor for High Torque Density

This paper proposes a V-shaped permanent magnet vernier (V-PMV) motor for potential applications in direct drive system. By designing suitable pole slot ratio and adopting the V-shaped PM topology and dummy slots in rotor, the flux leakage can be avoided effectively. Meanwhile, the high-order harmonics with large amplitude in the airgap magnetic field are fully utilized and served as the effective...
