摘要
 單繞組多速電動機，其轉子為籠型繞組，通過改變定子繞組的接法，從而改變其極對數，從而達到調速的目的。具有結構簡單、運行可靠、成本低廉等優點而被廣泛應用。在本文采用的是混相變極原理對單繞組變速電動機進行設計。
 本文首先要介紹單繞組多速電動機在現在社會生產的應用和發展，讓我們有明確的設計方向和意義。同時在以前的生產經驗的基礎和我們查閱資料的前提下，確定用混相法設計定子繞組的方案并做出分析，畫出槽號相位圖和繞組接線圖。同時把在設計過程中，我們需要了解的變極調速原理有深入的介紹，各種變極調速的方法原理及繞組排列，清楚單繞組變速電動機運行時的各種特性及設計特點。然后在電機的設計部分，先詳盡的敘述了電機設計程序及各主要參數的意義，同時通過給定的數據進行電機設計的計算。
 
關鍵詞 ：混相變極   ；槽號相位；  單繞組多速電動機。

Abstract
 
 The motor of many speeds of single winding, its rotor is a cage type winding, through change law of connecting , stator of winding , change logarithm very much its , thus achieve the goal of adjusting speed. Have of simple structure operating reliable , cost advantaging such as being cheap extensive application. In literary grace this it spends to be to is it become principle change speed to single winding the motor is designed very much to mix.
 This text should introduce the motor of many speeds of single winding in the application and development of social production now first, let us have clear design direction and meaning. At the same time the foundation and we of former production experience are consulted under the prerequisite of the materials, confirm that draws the picture of phase place of brass-wind instrument of trough and winding wiring diagram by mixing the scheme of designing the stator winding of the looks law and making analysis. In the course of designing at the same time, we need understand is it transfer speed principle have deep introductions very much to become, various kinds of is it transfer method principle and winding of speed arrange , clear single winding change speed motor operate various kinds of characteristics when and design the characteristic very much to become. Then some designs in the electrical machinery, exhaustive narration electrical machinery design program first and every main meaning of parameter, at the same time through carrying on the calculation that the electrical machinery is designed for the data definitely.
