Abstract
This paper presents the development of non-rare-earth magnetic gears for electric vehicles. Firstly, the magnetic gears which adopt either non-rare-earth or rare-earth permanent magnets (PMs) are discussed. Then, by using the finite element analysis, the electromagnetic performance of these magnetic gears are evaluated and quantitatively compared based on the same structure. Also, the natural magnetic characteristics of the non-rare-earth and rare-earth PMs are compared. Finally, a comparison of the cost-effectiveness among different types of PMs is carried out. The results indicate that the non-rare-earth PM material is preferred to the rare-earth PM material for application to magnetic gears.
