摘要

为了在驱动磁盘和输出磁盘相对转动时获得平稳的磁扭矩,提出了一种月牙形永磁体代替输出磁盘中的扇形永磁体的方法。通过使用磁场仿真分析软件Magnet~?仿真计算了磁扭矩值,发现选择7 mm厚硅钢片能获得较平稳的磁扭矩值。同时也研究了硅钢片局部存在磁饱和的状况,并通过选择合适的月牙形永磁体偏心圆弧的圆心位置和半径,获得了平稳的磁扭矩值。
        To obtain a smooth magnetic torque when the drive disk and the output disk were relatively rotated, a method of replacing the sector-shaped permanent magnets in the output disk with a crescent-shaped permanent magnet was proposed. The magnetic torque value was calculated by using the simulation software Magnet~?, and it was found that the selection of 7 mm thick silicon steel sheet could obtain a relatively stable magnetic torque value. The magnetic saturation of the silicon steel sheet was studied, and the smooth magnetic torque value was obtained by selecting the center position and radius of the eccentric arc of the appropriate crescent-shaped permanent magnet.
