Difference between Synchronous Motor and Induction Motor

WebThe speed of the rotor is always less than the rotating magnetic field or synchronous speed. The rotor tries to run at the speed of the rotor, but it always slips away. Thus, the motor never runs at the speed of the rotating magnetic field, and this is the reason because of which the induction motor is also known as the asynchronous motor. WebA 4 poles, 50 Hz induction motor has slip of 4 %. What is the actual speed of the motor? The synchronous speed of the 4 Poles,50 Hz induction motor is Ns= 120 x 50/4 = 1500 RPM.
