摘　　要：对一种新型的轨道交通制动装置,设计一种适用于这种装置的驱动电机。本文所设计的电机一般应用于自动控制设备中。但此电机与一般的无刷直流电机不同,正常工作在堵转状态。本文介绍了无刷直流力矩电机的组成及其工作原理,对转子磁路和绕组形式、永磁材料的选用进行深入分析,并采用等效磁路的设计分析方法,运用RMxprt设计计算电机械用无刷直流力矩电机。最终确定最优的设计方案,设计的电机满足装置要求,有良好的电磁性能。For a new type of rail transit brake device,a drive motor suitable for such a device is designed.The motors designed in this paper are generally used in automatic control equipment.But this motor is different from a normal BLDC and operates normally in a stalled state.This paper introduces the composition and working principle of BLDC,deeply analyzes the selection of rotor magnetic circuit and winding form,permanent magnet material,and adopts the design analysis method of equivalent magnetic circuit,and uses RMxprt to calculate the BLDC.Finally,the optimal design is determined.The designed motor meets the requirements of the device and has good electromagnetic performance.
