摘要
无刷双馈电机是一种新型感应电机,由于其定子上嵌有2套不同极对数的三相对称绕组,使其产生了不同于一般交流电机的性能。阐述了无刷双馈电机的基本结构和工作原理,对1台无刷双馈电机样机进行了双馈空载运行实验,测出了该样机在各种频率下的转速、电流,并对实验结果进行分析,得出了一些有用的结论。
The brushless doubly-fed machine（BDFM） is a new type of induction machine.Because it has two sets of the different pole pairs of the three-phase symmetrical windings embed in the stator,it possesses capability differ from general AC induction machine.The basic structure and operational principle of BDFM is analyzed in detail.On this base,design experiment program for the machine under empty running.The speed and current of the machine under different frequency are measured,meanwhile analyze it in detail.And we get some usefid results from the speed data.
