无刷双馈电机(brushless doubly-fed machine，BDFM)通过改变控制绕组的联接与馈电方式，可实现异步、同步、双馈亚同步和超同步等多种不同运行方式。然而，目前尚缺乏对BDFM异步运行模式的详细研究。该文提出了BDFM“单馈异步”和“双馈异步”运行模式的概念，结合笼型转子 BDFM的特点，阐述了两种异步运行模式的基本电磁关系，利用有限元分析得到了 BDFM 样机的气隙磁场波形，从而验证了两种运行模式均能产生恒定电磁转矩。通过对BDFM 样机在两种异步运行模式下的有限元分析和实验数据对比，表明 BDFM 单馈异步运行模式与普通异步电动机的运行特性相类似，在双馈异步运行模式下转速仍满足BDFM 的特征，且可通过改变控制绕组外串电阻实现调速运行。研究结果可为进一步深入研究 BDFM的运行规律提供参考。“,”By changing the control winding connection and feeding method of brushless doubly-fed machine (BDFM), many different operation modes can be obtained, such as asynchronous, synchronous, doubly-fed sub-synchronous and super-synchronous models. However, the detailed research about the asynchronous operation mode of BDFM is seldom. The concepts of “singly-fed asynchronous” and “doubly-fed asynchronous” operation modes were proposed. The basic electromagnetic relationship of these asynchronous operation modes were described in detail based on the features of BDFM with cage rotor. The air-gap magnetic field waveforms were analyzed by finite element, which verified that the constant electromagnetic torque could be produced at two different asynchronous operation modes. The results of finite element analysis and the comparisons of the test data show that the operating characteristics of BDFM singly-fed asynchronous mode are similar with induction motor, the speed still meet the characteristics of BDFM and can be adjusted by changing the external series resistance of control winding at doubly-fed asynchronous operation mode. The results can provide reference for studying the operation rules of BDFM in the further.
