Abstract

Magnetic gearboxes are becoming more attractive in gearing areas because of their high torque density and high efficiency. In this article, we proposed a 2-D analytical model in a coaxial magnetic gearbox by considering design aspects that can make the design process more reliable, efficient, and cost effective. The proposed analytical model is based on the solution of Laplace's and Poisson's equations for each subdomain, i.e., magnets, airgap, slots, and bars. The global solution is obtained using the boundary and continuity conditions. The analytical model can be used as a design tool for a magnetic gearbox with more design aspects compared with previously proposed methods. The analytical results of field distribution, induced bar current, and electromagnetic torque are obtained and compared with finite-element analysis (FEA).
