摘　　要：提出一种通过对无位置传感器无刷直流电机进行反电势检测硬件的优化方法。实验表明,用该方法调整的直流电机的最低转速比用通用调速方法调速的直流电机的最低转速要低4.5%左右,有效扩大了调速范围。An method to optimize the hardware of Non-position inspection for DC brushless motor was put forward to inspect the inverse counter electric motive force for DC brushless motor. Experimental result showed that the rated lowest speed of the DC motor by this method was 4.5% lower than the rated lowest speed of the DC motor by the general speed-regulation method, expending the speed-regulation range.
