摘　　要：通过对无刷直流电动机(BLDCM)工作原理分析,给出一种基于STM32无位置传感器的BLDCM控制系统设计方法。采用硬件获取换相点降低了对控制器性能的要求,该系统主要包括换相点检测电路、电动机驱动电路、电流检测及保护电路、通信接口等。采用速度和电流双闭环控制,稳定了电动机的输出转矩,提高了电动机的响应速度。实验结果表明该设计具有控制精度高、响应速度快、运行稳定可靠等特点。A design method of sensorless BLDCM （brushless DC motor） control system based on STM32 is given by analyz- ing the working principle of BLDCM. The hardware is adopted to obtain the commutation point to reduce the requirement for the controller performance. This system mainly includes the commutation point detection circuit, motor drive circuit, current detec- tion and protection circuit, communication interface, etc. The speed and current double closed-loops control is used to stabilize the output torque of the motor and improve the response speed of the motor. The characteristics of high control precision, fast re- sponse, stable and reliable running are verified with experiments.
