Electrical Engineering XYZ MCQ on Which type of magnetic field is produced by stator of 3 phase induction motors.
Stator of 3-phase induction motor produces:
- Rotating magnetic field
- Alternating magnetic field
- Steady magnetic field
- None of these
Correct answer: 1. Rotating magnetic field
Explanation: The stator of a 3-phase induction motor is responsible for generating a rotating magnetic field. This rotating magnetic field is crucial for the operation of the motor. When a 3-phase AC voltage is applied to the stator windings, it produces a magnetic field that rotates in space. This rotating magnetic field induces a voltage in the rotor windings, which in turn generates a rotor current and produces a torque, causing the rotor to turn.
