Three Phase Induction Motor – Working Principle

05.07.2021  A three phase induction motor has a stator and a rotor. The stator carries a 3-phase winding called as stator winding while the rotor carries a short circuited winding called as rotor winding . The stator winding is fed from 3-phase supply and the rotor winding derives its voltage and power from the stator winding through electromagnetic induction .

Experiment #6: Three Phase Induction Motor - UMD

The three phase induction motor (IM) is very similar to the three phase transformer in ex-periment #3. Besides transformer action, the IM has motion. If the IM were restrained so it would not rotate, then it would be similar to a transformer. If there are no connections to the rotor, then the rotor is shorted on itself and the IM (blocked rotor) is similar to a short circuited
