摘　　要：设计了一个高速无刷直流电动机全数字锁相稳速系统,通过单片机与CPLD的合理配合,使系统以简单的电路实现了对电机转速的高精度控制。经实际测量,电机能快速起动并进入锁定状态,其反馈转速的转子位置传感器输出脉冲信号能稳定跟踪给定基准脉冲,转速稳定精度高;在额定转速下长时间工作时,系统有效抑制电机转速的漂移。试验表明,该系统实用性强,具有较高的工程应用价值。A constant - speed system of BLDCM with all - digital phase - locked loop was designed. By means of proper coordination between signal - chip and complex programmable logic device（CPLD） ,the high precision speed control with simple circuit was realized. According to the measurement, the motor can be started quickly and locked, and its feedback speed - pulse which produced by rotor sensor trailed reference pulse stably and accurately, then the system depressed the speed drift of BLDCM effectively at rated speed for long time working. The result of the test showed that the system was practical and valuable.
