To adjust the rotational speed of an asynchronous motor, we can start with changing the following three parameters: the number of pole pairs of the stator winding, the slip ratio of the motor, and the frequency of the power supply. Changing the first parameter affects the synchronous speed. Changing the second parameter only enables speed […]
