Abstract: Brushless doublyfed machine(BDFM) retains most merits of common doublyfed machine. Whats more, it increases the operational stability and reduces the maintaining costs by removing the slip ring and brushes. Therefore it has a wide application in the variable speed constant frequency power systems, such as ship shaft generator, water power and wind power generation, and the controlfrequency adjustable speed drive systems, for instance, the fan and pump load drives. In this paper, introduced the structure characteristics, operational principles of BDFM and control strategies, and summarized its development of the key technology. Aiming at the present shortcomings of BDFM, the tendency and direction of the future development were discussed.
