Abstract

Rare earth permanent magnets (PMs) with a large energy product are generally used in the traction motors of hybrid electric vehicles. However, developing rare-earth-free motors is necessary because of problems with rare earth materials, such as increasing prices and difficulty in their supply. This paper introduces such a rare-earth-free motor: a ferrite PM axial gap motor with a coreless rotor structure. The motor structure and the results of three-dimensional finite element analysis are described in detail.
