Abstract: Design and calculation of magnetic circuit is the core sector for design of permanent magnet speed controller. In this paper, a magnetic conductive disc, which was installed between copper disc and conductor disc, was used to optimize magnetic circuit structure of permanent magnet speed controller. The dynamic magnetic field of permanent magnet speed controller comprising magnetic conductive disc was simulated using COMSOL software, and the magnetic circut structure and its optimization effect were analyzed. Simulation results show that magnetic conductive disc is capable of increasing magnetic energy use ratio of permanent magnet, improving distribution of magnetic line which penetrates copper disc, and increasing transmission torque of permanent magnet speed controller. In addition, this paper also analyzed the influences of conductivity and thickness of magnetic conductive disc on transmission torque of permanent magnet speed controller, and provided theoretic basis for reasonable design of magnetic circuit of permanent magnet speed controller by selecting proper thickness and magnetic conductivity and magnetoconductive material.
