Parametric Design and Optimization of Magnetic Gears with Differential Evolution Method

Recently, magnetic gears have drawn wide attention due to their inherit merits, such as high torque density and overload protection. In this paper, an analytical calculation based on MMF -permeance theory is adopted to analyze the modulation effect in magnetic gear. After that, an automatic drawing procedure is built to rapidly analyze the parameters. The effects of some key parameters on magnetic gear performance are investigated, including air slot opening to pole pitch ratio Co, magnet-arc to PM pole pitch ratio α and PM thickness hm• In particular, three types of steel pole-pieces are considered, which are radial slots, parallel teeth and parallel slots. At last, a global optimization design is carried out by using differential evolution algorithm, and some useful suggestions are given for the design and optimization of coaxial magnetic gear.
