單繞組多速電動機的研究及控制線路設計摘要：鼠籠式非同步電動機的變極調速雖然是有極調速，但具有簡單、可靠、及高效的優點，在對調速要求不高的許多生產機械中有廣泛的應用。本文比較地詳細介紹了的.單繞組多速電動機的現狀、發展狀況及其在我國的應用前景，介紹了變極調速的原理，YD132M4/2極變極調速電機的繞組方案選擇的依據及其主要引數計算及其電磁設計。
關鍵詞：電動機；單繞組；變極調速The research of the single round to several-speed electric motor And control circuit design
ABSTRACT：The rat cage type an electric motor changes the pole adjusts speed although is an advantage to have pole adjust speed, have simple, dependable, and efficiently, have the extensive application in made exchange soon request not high and many productions text was comparatively detailed to introduce single to round a many soon present condition, development condition and its applied foreground in our countries of the electric motor, introduced to change the principle that pole adjust soon, the YD132M4/2 changes very the pole adjusts soon the electrical engineering rounds a basis of project choice and its main parameter calculations and its electromagnetism designs.
Key words:Electric motor;single round ;Changing the pole adjusts speed
