If a 3-phase supply is given to the stator and rotor is short circuited rotor will move___________?
Correct answer: B. in the same direction as the direction of the field
- A. in the opposite direction as the direction of the rotating field
- B. in the same direction as the direction of the field
- C. in any direction depending upon phase squence of supply
Explanation
The rotating stator field induces rotor currents whose interaction produces torque in the same direction as the rotating field. The rotor therefore turns in the field direction, although it never reaches synchronous speed.
