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. Keyword: Mix becoming very much; Phase place of brass-wind instrument of trough ; Motor of many speeds of single winding
