摘要：单绕组多速电机是一种现代社会使用范围较大的电机，广泛应用于人们的生产活动和日常生活。该电机技术性能指标已经达到国家标准的基础上，进一步减少电机的噪声、提高电机的效率、节约能源、尽可能节约原材料、降低产品价格。根据市场需求设计出满足用户使用要求的单绕组多速电机。该机即有较大的启动转矩和较高的力能指标．从分析其运行原理入手，介绍了其设计方法和工艺要求并进行了技术经济指标的分析对比。
单绕组多速电动机，其转子为笼型绕组，通过改变定子绕组的接法，从而改变其极对数，从而达到调速的目的。具有结构简单、运行可靠、成本低廉等优点而被广泛应用。在本文采用的是反相变极原理对单绕组变速电动机进行设计。

The inversion place and change-pole Research of the motor of many speeds of single winding
Abstract：The single reel group electrical machine is one kind of the electrical machines that are widely used by modern society, which is widely applied to people’s produce activity and everyday activity. A single –phase resistance starting capacitance running induction-motor is designed according to market requirement in this paper. This motor has the merit of resistance starting and capacitance running induction-motor, namely it has biggest start torque and energetic indicate. Then design method and t technical need are improved. Finally technique and economy inversion is construct.
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. [11]
