摘　　要：针对具有霍尔位置传感器的无刷直流电动机,以dsPIC30F2010为核心控制单元,给出了一种正弦波驱动无刷直流电动机的新方法。根据三相Hall位置信号所包含的位置和速度信息,获得正弦调制波的周期和幅值,并利用不对称规则采样法生成六路SPWM信号。仿真和实验结果显示该方法能够在低成本的前提下,实现正弦波驱动无刷直流电动机平稳运行。Aiming at BLDCM with a Hall rotor position sensor,a new method of sine-wave driving BLDCM was provided,in which dsPIC30F2010 was regarded as the core control unit.The period and amplitude of the modulating sine wave were obtained according to the position and velocity information included in the three-phase Hall signals.Then using the asymmetry regular sampling,six sine pulse width modulation（SPWM） signals were generated.Simulation and experimental results show that this method can make BLDCM driven by SPWM stably under the condition of low cost.
