WebThe rotor needs to be rotated at a speed near to the synchronous speed during starting. If done so, the rotor poles get magnetically coupled with the rotating stator poles, and thus the rotor starts rotating at the synchronous speed. Synchronous motor always runs at a speed equal to its synchronous speed. i.e. Actual speed = Synchronous speed WebElectrical Engineering questions and answers.

WebApr 13, 2024 · However, to fully understand how an induction motor works, it is necessary to understand the concept of slip frequency. The slip frequency is the difference between the synchronous speed of the motor's magnetic field and the actual rotor speed. When the rotor is stationary, the slip frequency is equal to the synchronous frequency of the power ... WebThe rotor of an induction motor runs at a speed other than synchronous speed. In other words, there lies a relative motion between the rotating magnetic field and the rotor. That’s why this motor is also known as an asynchronous motor. The speed of an induction motor reduces as the mechanical load on it increases.
