ABSTRACT：The rat cage type an electric motor changes the pole adjusts speed although is an advantage to have pole adjust speed, have simple, dependable, and efficiently, have the extensive application in made exchange soon request not high and many productions machine.This text was comparatively detailed to introduce single to round a many soon present condition, development condition and its applied foreground in our countries of the electric motor, introduced to change the principle that pole adjust soon, the YD132M4/2 changes very the pole adjusts soon the electrical engineering rounds a basis of project choice and its main parameter calculations and its electromagnetism designs.
Key words:Electric motor;single round ;Changing the pole adjusts speed
