无换向器电动机在窑尾排风上的应用

Application of Motor Without Commutators in Cave Tail's Releaser

阐述了自控变频无换向器电动机调速系统的基本原理、线路结构和其独特的优点 -集交直流电动机的优点于一身 。

The paper,at first,expatiates the basic principle on motor adjustable speed system without commutators,as well as connection configuaration,the unique virtue which gets the virtues of direct current motor and the ones of alternating current motor together. Then,it summarizes the situation on which the system is applied in the cave tails releaser of cement gyration.
