无刷双馈电机控制与应用前景

无刷双馈电机(BDFM)是一种新型交流电机,它兼有异步电机和同步电机的共同优点,去掉了转子侧电刷,提高了机械稳定性,降低了维修成本。本文详细综述了无刷双馈电机的发展历史、运行原理、数学模型、控制策略,简单介绍了无刷双馈电机的应用,并对其发展前景作了展望。

The Brushless Doubly-fed Machine Control and Application Prospect

The brushless doubly-fed machine （BDFM） is a new kind of Ac motor. It has the Common advantage of both induction motors and synchronous motors. By taking out the brush of rotor side, the mechanical stability of BDFM is improved and maintenance cost reduced. This paper summarizes in detail of the history the operation principle the mathematical model and the control strategy of BDFM. The applications of BDFM are introduced simply and the development prospects are described.
