摘　　要：分析了梯形波反电动势无刷直流电动机实现正弦波电流驱动的方法。采用高性能数字信号控制器dsPIC6010构成了无刷直流电动机控制系统;给出了实验波形,证明了所用方法和设计方案的正确性。Square-wave current drive and sine-wave current drive of trapezoidal back-EMF waveforms of BLDCM were introduced and the work principle of sine-wave current drive was presented in this paper. Adopting the DSP chip dsPIC30F6010, the control system of BLDCM was designed. Experimental results showed the rationality and the validity of the method of sine-wave current drive.
