Abstract

Throughout the years Hybrid Electric Vehicles (HEV) require an electric motor which has high power density and wide constant power operating region as well as low manufacturing cost. For these purposes, a new concept permanent magnet motor is designed and analyzed with the basic theories about Interior Permanent Magnet Synchronous Motor (IPMSM).

This new motor has DC excitation coils and flux paths, which can increase the output torque and be controlled for field weakening operating. The analysis has been conducted by three-dimensional Finite Element Analysis. The results show the possibility of the new motor for HEV applications. The new motor has several advantages: low manufacturing cost, low inertia of the rotor, and the direct controllability of air-gap flux.
