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

Blog Article

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 jmannino.com magnetic field are fully utilized and served as the effective working harmonics, which aim at enhancing the output torque and reducing the torque ripple.Moreover, to extensively explore the performance advantages of the V-PMV motor, a multi-objective optimization study is carried out.And, the electromagnetic performances of the V-PMV motors are analyzed and compared in detail.

Finally, a prototype machine is built dodge warlord for sale and tested.Both theoretical analysis and experimental results verify the validity of the motor and multi-objective optimization design approach.
