摘　　要：稀土永磁无刷直流电机正/反转的实现不同于其它电机。为了缩短正/反转过渡过程时间,减小过渡过程中能量损耗,提高效率,对电动舵机系统的方波永磁无刷直流电机正/反转的实现方法进行详细分析,并根据电机的基本公式,解得正/反转过渡过程的转矩、转速动态方程,利用M atlab进行仿真,最后通过实验验证了分析的正确性与实用性。The method of the forward/reversal rotation of rare earth permanent magnet brushless DC Motor（BLDCM） is different from other motors.For reducing the transient time and energy dissipation,improving efficiency,the reality of the forward/reversal rotation of the square wave BLDCM used in actuator is analyzed in detail.According the basic formula of mathematical model,the transient equations of torque and velocity are solved, which are simulated by the software of Matlab.The experimental result verifies the reasonability and validity of the conclusion.
