文档介绍：摘 要
电机是把电能转换成机械能的设备，它是利用通电线圈在磁场中 受力转动的现象制成。电动机按使用电源不同分为直流电动机和交流 电动机。电力系统中的电动机大部分是交流电机，可以是同步电机或 者是异步电机。同步电机的转速与所接电网的频率之间roducts. Along with the science and technology unceasing innovation and the rapid development of industry and agriculture, electrification and automation level increases, national economic sectors for induction motor requirement increasingly, its performance, quality, technology, economic indicator of the corresponding put forward more and more high demand. Therefore, the varieties of asynchronous motor, must make timely update and development to adapt to each new industrial field, the special requirements of different, especially to the great demand for small and medium asynchronous motors, guarantee the quality of its operation in, long life and can satisfy the requirements of the use and at the same time, further save copper, iron and other materials, improve efficiency and power factor, in order to enhance the technical and economic indexes, lower power consumption, this is just for induction motor design work out to the higher request.
This paper expounded three-phase asynchronous motor principle of work and on the foundation of basic structure, according to the given design parameters and the requirements of key performance index, completed the asynchronous motor design work. The subject of the three-phase asynchronous motor design in accordance with the design of concrete programs include motor parts of the structure design, the design of the magnetic circuit part, parameter calculation, the working performance of the calculation and the calculation of the five most starting performance design work. One of the working performance of the calculation and starting performance calculation is in the structure design, the design of the magnetic circuit part of the design, parameter calculation based on the results of the completed. And in the structural design and set including rotor slot type selection and design of the magnetic circuit, design,
