定子双馈电机用于水泵类负载调速时的优势研究

Superiority Research on Stator Doubly-fed Machine for Pump-type Load Adjusting Speed

提出了一种新型定子双馈无刷变频调速电动机．当它用于驱动水泵类负载时，不仅具有常规变频调速的节能优势，而且可大大降低所需变频器的容量．文中介绍了该种电机的结构和工作原理，给出了实验样机的调速特性．对将其用于水泵类负载时的优势进行了分析．

A new type of stator doubly-fed brushless adjusting sped machine is put forward. Whenthis kind of machine is used to adjust speed of the pump-type load, not only the energycan be saved, but also needed converter power can be reduced greatly. The machine strUCture,operating principle and adjtisting speed charaCteristic have been discribed. And its superiorityfor driving pump-type load has been also discussed in this paper.
