2019年10月1日 · There are two methods by which the speed of the induction motor can be monitored (controlled). The first one is to change the synchronous speed (n sync) which is the speed of rotation of the magnetic field of the stator and the rotor. The second method is to change the slip (s) of a motor according to the load on the shaft of the motor.

Induction Motor Speed Control Methods: The only way to control the speed of a synchronous motor is to control the input frequency and voltage such as to keep V/f constant. The Induction Motor Speed Control, on the other hand, can be controlled by the following means:

There is a various method of speed control of an Induction Motor. The rotor speed of an induction motor is given by the equation shown below. From equation (1) it is clear that the motor speed can be changed by a change in frequency f, a number of poles P, and slip s.

Induction motor speed control is a process of manipulating currents in an induction motor to regulate speed. While often used in fixed frequency applications, induction motors are popular for variable frequency applications such as industrial drives and electric vehicles.
