According to the characteristics of the pole-changing induction motors, the calculating model of the chain equivalent circuit was established and the electromagnetic design program of the traditional medium and small three-phase induction motors was modified and improved. The CAD system of the three-phase single winding pole changing squirrel cage asynchronous machine was developed by using the software of Visual C＋＋6.0. The calculating example in the paper indicated that the results of this system were accurate and the system had practical value for designing the pole-changing induction motors quickly by using the computer.
