摘要: 设计一种新型结构的电磁失电制动器。制动部分由多层制动盘环节叠加组成,与传统制动器相比可以提升制动器扭矩,减小制动器体积;动铁心与静铁心的接触端面采用凹凸结构错位设计,使得实际初始磁路气隙远小于制动器中动铁心和静铁心间的实际工作间隙。电磁仿真对比验证了该结构设计是可行的,可以达到优化磁路、减小体积、提高制动器的转矩和响应速度的作用。

Abstract: A new structure of electromagnetic brake was designed. The brake part was composed of multiple brake disc links, which can increase the brake torque and reduce the brake volume compared with the traditional brake. The contact end of the moving core and the static core adopted concave convex structure dislocation, which made the actual initial magnetic circuit air gap much smaller than the actual working gap between moving core and static core in the brake. Electromagnetic simulation was carried out, it is verified that the structure design is feasible, which can optimize the magnetic circuit, reduce the volume and improve the torque and response speed of the brake.
