摘　　要：为了提高无刷直流电动机伺服控制器的控制精度、降低无刷直流电动机伺服控制器的成本,采用LM629芯片设计了一种无刷直流电动机伺服控制器,搭建了伺服控制器的硬件平台,开发了伺服控制器的控制软件。针对工业应用中对直流伺服电机进行位置控制的要求,提出了数字位置控制模式。通过对伺服系统速度波形进行分析,验证了该系统具有较高的控制精度。In order to improve the precision of servo brushless DC motor driver and reduce its cost, a servo brushless DC motor driver based on the integrated circuits LM629 was designed, and hardware and software were established. A digital position servo module was introduced to meet the demand for the position control of industry. The analysis of the wave of the speed shows that the driver provides good precision when driving brushless DC motor.
