摘　　要：在阐述无刷双馈电机原理的基础上,推导了其双馈运行时控制绕组的调频范围。在Ansoft/Maxwell环境下建立了回路型、带公共笼条无公共端环和有公共端环三种不同转子结构的无刷双馈电机有限元分析模型,分别对三种不同转子结构BDFM双馈运行状态时控制绕组加不同压频比及相同压频比时的动态特性,以及同步运行状态时控制绕组加不同电压时三种BDFM的动态特性进行仿真,并进行比对分析,为进一步研究无刷双馈电机奠定理论基础。The deduction of control winding frequency range based on the principle of the brushless doublyfed machine（ BDFM）. The Ansoft /Maxwell was used to establish rotator of loop type,rotator with public bar with public end ring and without public end ring finite element model of BDFM. By using the model respectively do some simulation analysis about the three kinds of BDFM control winding voltage with different and same ratio of voltage in the state of doubly fed operation,get the dynamic characteristics and compare under the various operation conditions. At the same time,simulation gained the effects of different control winding voltage to three kinds of BDFM in the condition of synchronous operation,laying the theoretical foundation for the further study of the BDFM.
