Doubly Fed Machine

Brushless Doubly Fed Machine (BDFM) shows economic promise as a variable speed drive or generator. Seeking for rotor structures with higher modulation effect will be the most important role at present for improving the efficiency and performance of BDFM. After presenting the principle and providing the parameters of BDFM, this paper analyzes the air gap flux density of BDFM with different rotor structures and various pole numbers by using finite element analysis software ANSOFT. The effect of rotor structures and pole numbers on magnetic field modulation of BDFM can be obtained, these conclusions could lay the foundation for BDFM structure optimizing design.

Rotor Structure

Brushless doubly fed machine (BDFM) has rapid progress in recent years, rotor modulation capability is still the role factor which limits the popularization and application. Rotor structure is designed derived from the common reluctance in this paper, finite element analysis(FEA) is used for the optimization of the rotor. By studying the optimization comparatively, design program of rotor structure can be obtained, which shows great feasibility in industrial and agricultural production.
