In which of the following motors the stator and rotor fields rotate simultaneously?
Correct answer: D. Synchronous motor
- A. D.C. motor
- B. Reluctance motor
- C. Universal motor
- D. Synchronous motor
- E. Induction motor
Explanation
In a synchronous motor, the stator's rotating magnetic field and the rotor's magnetic field rotate together at synchronous speed. In an induction motor, the rotor field has slip relative to the stator field.
