A Novel Coaxial Magnetic Gear Using Bulk HTS for Industrial Applications

In this paper, a novel coaxial magnetic gear (CMG) using bulk high temperature superconductors (HTS) is proposed. By substituting bulk HTS for ferromagnetic material, a novel stationary ring is resulted, which can not only provide the desired field modulation effect but also suppress the end-effects that commonly occurred in the traditional CMG. The performance of the proposed bulk HTS CMG is assessed and then verified by using finite element analysis.
