什么是正弦波驱动？
正弦波驱动根据转子的旋转角度，以正弦的形式连续改变定子线圈的电压，从而使转子旋转。
根据频率的不同，电机的3相会有一定的“延迟”。
与方波驱动相比，它的效率更高，产生的振动和噪音更小。
控制时，需要检测转子位置。
通常，使用三个位置传感器每隔60度检测一次位置，实时估算转子位置，并输出与转子位置相符的正弦波电压。
采用逆变电路驱动电机，通过PWM控制实现电压的连续变化。
如果正弦波为1Hz，那么“播放”这个正弦波需要一秒钟。如果第二波“偏移120度”，那么该第二波将在第一波之后0.33秒正好开始，也就是完整时间的三分之一。第三波将再次开始偏移120度，即第一波开始后0.66秒。
这是为了适时控制直流无刷电机的U、V、W相。
根据3相的时间顺序，电机将顺时针或逆时针旋转。
