Abstract:

Aiming at the current problem of having no accurate and effective method in brushless doubly fed machines rotor design, decoupling method for optimal point parameters was put forward. The salient pole and magnetic barrier rotor was optimized and designed for the first time and the corresponding best parameters combination of salient pole and magnetic barrier rotor for magnetic field modulation ability was got. According to the comparison with magnetic barrier rotor, the conclusion was reached that salient pole and magnetic barrier has higher output voltage amplitude, but weaker magnetic field modulation ability, which also indirectly proved the feasibility and correctness of the decoupling method for optimal point parameters. It will provide a practical and feasible optimization method for the development of brushless doubly fed machines rotor.
