Abstract :
Owing to the stator and rotor windings fed by different power sources and the asymmetry of the rotor structure, the analyses on the air-gap flux-oriented control of a synchronous motor are more difficult than for an induction motor. The paper elaborates the decoupling characteristics of the air-gap-flux-oriented control for a synchronous motor considering the rotor salient pole effect and the rotor damping windings. It is pointed out that the air-gap flux-oriented control does not realize steady and dynamic decoupling control for a synchronous motor. The results are verified by the feasible simulations and experiments
