摘　　要：无刷双馈电机是一种新型的适于变频调速系统使用的电机,其结构型式和工作原理与传统交流电机相比具有较大的区别.针对转子结构为笼型短路绕组的无刷双馈电机,建立了其在转子旋转坐标轴下的d-q数学模型,导出了电磁转矩表达式,并应用该模型对该类电机的控制特性进行了仿真研究,仿真结果验证了模型的正确性.The brushless doubly-fed machine （BDFM）, whose structure and operation principle are different from a conventional AC machine, is a new type of machine suitable for variable frequency adjustable-speed system. A mathematical model of d-q for cage-rotor brushless doubly-fed machine is established, and an expression of electromagnetic torque is developed, meanwhile the control characteristic simulations based on the d-q model are made. The simulation results prove the validity of the d-q model.
