无刷双馈电机的电磁结构分析

无刷双馈电机作为一种可作电动机或发电机运行的异、同步通用交流电机，无论是工作原理还是其结构特点都有其特殊性。本文从鼠笼式无刷双馈电机稳定运行时定转子电流产生的磁势入手，分析了刷双馈电机的工作原理，阐述了定转子结构的设计特点，为无刷双馈电机的设计提供了理论依据。

THE ANALYSIS OF THE ELECTROMAGNETIC MACHANISM OF BRUSHLESS DOUBLY-FED MACHINE

As a kind of asynchronous and synchronous general purpose a.c.machine,which can be run as a motor or a generator,the Brushless Doubly Fed Machine(BDFM)possesses its particular features either in operation principle or in structure.In this paper,the MMFs established by the stator and rotor currents of the BDFM at the steady state are analyzed,the operation principle are discussed,the design features for the stator and rotor structure are explained,which offer the theoretical foundation for the machine design.
