摘　　要：针对现有同步电机存在的问题,提出一种新型同步电机。该电机省去了滑环和电刷,通过调节励磁电流的大小和方向使发电机的输出电压可调。描述了电机的结构及原理,计算了发电机的空载特性。结果表明,电机的空载电势可以通过励磁电流方便地调节,电机的可靠性增加,但体积也有所增大。Aimed at the problems of existing synchronous machines, this paper proposes a new type of synchronous machines, which does not use slip rings and brushes. It is possible to regulate the output voltage by adjusting magnitude and direction of the exciting current. The structure and principles of the machine are described, and the generator load characteristics are calculated. This study shows that no-load voltage can be adjusted when excitation current varies, and the machine＇s reliability increased, while the machine size is increased.
