摘　　要：针对低速永磁无刷直流电动机,介绍了一种数字式闭环稳速控制系统。采用脉冲串转速给定方法,并直接利用无刷电动机自身转子位置传感器输出信号进行速度检测,有效地解决了低速无刷电机无转速传感器高精度稳速控制,系统可靠性高、抗干扰性强,还可使电动机功率驱动器具有互换性,适于规模化生产。A digital close - loop speed stabilized control system based on low speed permanent magnetic brushless DC motor is introduced in this paper. The methods of speed given signal adopting pulse frequency and speed feedback signal direct measuring the rotator position sensors of BLDCM are discussed. It is efficacious that the ideas can make the motor speed operating in high accuracy stability, and have not only high reliability and anti -disturbance,but also the exchangeability to the power driver of BLDCM in a great deal production.
