Which of the following statements regarding reluctance-start motor is incorrect ?
Correct answer: A. It is similar to reluctance motor
- A. It is similar to reluctance motor
- B. It is basically an induction motor and not a synchronous one
- C. So far as its basic working principle is concerned, it is similar to shaded pole motor
- D. the air-gap between rotor and salient poles is non- uniform
Explanation
A reluctance-start motor is fundamentally an induction motor with a non-uniform air gap and salient rotor, and its starting action resembles that of a shaded-pole motor. It should not be identified simply as an ordinary synchronous reluctance motor, so statement a is the incorrect one.
