摘要：
A new method about sensorless real-time rotor position detecting based on electrically excited synchronous motors is proposed. The key idea is when high frequency signal is injected in the motor, the information about real-time rotor position can be detected in back electromotive forces. The theoretical derivation about how to detect the rotor position information and a key problem of signal processing are given in this paper. By the experimental verification, high frequency signal injection rotor position detecting method is feasible.
