Has the structure to be simple, the manufacture is easy, firm durable, the service is convenient, cost inexpensive and so on a series of merits. Because it has the high efficiency and approaches in the constant speed load characteristics, it can therefore satisfy the most of the industrial and agricultural production machinery drag requirements, thus becomes in each kind of electrical machinery the output to be biggest utilizes the broadest one kind of electric motor. The graduation project is the availability of electrical theory and design principles the basis of light of the specific design requirements, through the induction motor electromagnetic design, from thin into rated data and the main parameters, calculation of magnetic circuit, parameter calculation, Performance computing and calculation of Starting Performance of Starting Performance of five parts, qualified to design a performance of a small three-phase asynchronous motor, by changing the gap size and change the number of conductors per slot two optimization program, the final design with excellent performance by a small three-phase asynchronous motor. Through this design, understanding the development of domestic and foreign asynchronous motor, electromagnetic motor control design process and learn to find the corresponding chart data needed to understand the use of computer design concept of motor program, throu
