摘要
对永磁梯形波无位置传感器无刷直流电动机的转子位置检测及启动进行了研究,给出了以数字信号处理器TMS320F240为控制核心的系统结构,并将该无刷直流电动机带位置传感器和不带位置传感器运行时定子端电压波形进行了比较,试验证明了该方法的正确性和有效性。
It is studied the rotor position detection and starting of the permanent-magnet brushless DC motor (BLDCM) without any position sensor. The system structure based on TMS320F240 is given. The stator voltage waveforms of the motor with and without position sensor are compared. The test shows the correctness and effectiveness of the method.
