Current induction motor

WebSelecting a reduced voltage reduces the starting current for the motor. As the induction motor picks up speed, a mechanism shifts the tapping to increase the applied voltage. When the induction motor attains full speed, it finally disconnects the auto-transformer from the circuit, and thus, the rated voltage appears across the motor terminals. ...
