The key points of sensorless technology in PMBLDCM are to study a method which can detect rotor position accurately by simply method in whole speed range. After analyzing current sensorless methods of the PMBLDCM, it is found that those methods are successful at middle and high speed, but they often fail to detect rotor position at low speed when the back electromotive force is small or zero.

纵观目前的永磁无刷直流电机的无位置传感器控制方法，比较成熟而可行的方法多集中于电机在中高速区域运行时，能够较准确估计转子位置；电机处于低速、极低速、静止状态时电加热管，因为反电动势幅值较小或者为零，而无法正常工作。

Its thought is to change the model of the asynchronous motor through the coordinate, make it become direct current motor model, divided the electric current vector of the stator into according to the weight of two pieces of direct current with directional magnetic field of the rotor and controls, realize magnetism coherent and torque solve lotus root control , in the hope of the control result of the direct current reaching machine.

其思想就是将异步电动机的模型通过坐标变化，使之成直流电动机模型，将定子电流矢量分解为按转子磁场定向的两个直流分量并分别加以控制，从而实现磁通和转矩的解藕控制，以期达到直流电机的控制效果。
