Research on Automatic Detection Method about Rotor Initial Position of Permanent Magnet Synchronous Motor

Abstract:

ts required to real-time detect rotor position for vector control of permanent magnet synchronous motor, the difference is initial rotor position angle between the output position signal of absolute rotary transformer and the position signal for park transformation, then it is necessary to get the initial position of the motor before the motor starts. Based on the characteristics of permanent magnet synchronous motor, a certain method about automatic detection of the initial position of a rotor is obtained. Compared with other methods, there are advantages such as simple calculation, small impact by the external and high detection accuracy. At last, the correctness of the method is verified by theory and experiment.
