Which of the following statements regarding repulsion-start induction motor is incorrect ?
Correct answer: C. In fractional horse power motors, it has replaced the capacitor motors
- A. It requires more maintenance of commutator and other mechanical devices
- B. It makes quite a bit of noise on starting
- C. In fractional horse power motors, it has replaced the capacitor motors
- D. It is not easily reversed
Explanation
Repulsion-start induction motors have high starting torque but require commutator maintenance, produce noise, and are difficult to reverse. They did not replace capacitor motors in fractional-horsepower applications, so that statement is incorrect.
