When the rotor is stationary, the two torques produced are equal and opposite. Hence, at standstill, the net torque is zero.

The stator is fed from a 3-phase supply of voltage V/phase and frequency f Hz. The rotor is wound 3-phase for as many poles as the stator and is short-circuited.
Webb31 okt. 2024 · Induction Motor Working Principle Now the induced current in the rotor will also make an alternating flux around it. According to Lenz’s law, the induced rotor current direction will tend to resist the cause of its production. Induction Motor Protection System The basic idea of this project is to give safety to the Induction Motor. WebbHence an induction motor can only operate efficiently at low values of slip. Torque: We can also obtain the relationship between the power entering the rotor and the torque developed. We know that mechanical power is torque times speed, and that when the slip is s the speed is (1 – s)ω s , where ω s is the synchronous speed.
