Torque Slip Characteristics of Induction Machine

WebEquation 1. In the supply-frequency equivalent circuit, the secondary e.m.f. is E 2, rather than sE 2, so to obtain the same current in this model as given by equation (1), we require the slip-frequency rotor resistance and reactance to be divided by s, in which case the secondary current would be correctly given by. Web13 apr. 2024 · 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 supply, typically 50 or 60 Hz. As the rotor begins to turn, the slip frequency decreases, causing the motor to speed up ...
