摘　　要：系统阐述了无刷直流电动机的基本原理和工作特性,比较分析了无刷直流电动机不同控制策略下的数学模型及拓扑结构。为了分析换相电流及转矩脉动的原理,基于上、下桥臂PWM调制换相控制方法进行理论及仿真分析,通过仿真验证了所分析方法的正确性和有效性。The basic principles and operating characteristics of the permanent- magnet brushless DC motor were described,and a comparative analysis of the mathematical model and the topology under different control strategies was given.In order to analyze the principles of commutation current and torque ripple,control theory and simulation analysis based on the upper and lower arm PWM modulation commutation method were adopted. The simulation results show the correctness and validity of the commutation control method.
