三相异步电动机电气制动分类方法之述介和比较

Description and Comparison of Electric Braking Classification of Three-Phase Asynchronous Motor

指出多数文献所认为的三相异步电动机电气制动分类方法是不合理的。合理的分类方法是"三反一耗":反转、反接、反馈和能耗。认为三相笼式异步机反接制动时,应该在定子边串入一定的电感,以便限制过大的电流。对此,已有文献普遍缺乏认识。

This paper points out that the electric braking classification of three-phase a-synchronous motors recognized by most references is not reasonable.The reasonable classifica-tion method is"three reverses and a consumption":reverse rotation,reverse connection,feed-back and energy consumption.This paper deems that when the three-phase cage asynchronous motor is braked in reverse connection,a certain inductor should be connected to the stator side in order to limit the excessive current.In this regard,there is a general lack of understanding in the existing literature.
