摘要
对无传感器无刷直流电机的驱动系统进行了研究 ,详细论述了开关电容低通滤波器的设计方法。给出了电动自行车电机驱动的部分电路和信号波形。
In this paper a driving system with sensorless and brushless DC motor is studied,the lowpass design method for switching capacitor is discussed in detail.And some circuit diagrams and signal waves for the motor driving system of motor-bicycle are given.
