In this paper, pole-changing induction motor has been studied. To control the speed of the induction motor, many various methods can be used. Compared to the other speed control method, pole changing method is simple, cost effective, and reliable. From this research, pole changing induction motor with 2 and 4 pole windings are analyzed and designed, of which rated torque is about 2Nm. A real induction motor is also fabricated and some experiment has been performed showing that the analysis and experiment results are similar.
