Slip ring motor is recommended where____________?
Correct answer: D. all above features are required
- A. speed control is required
- B. frequent starting, stopping and reversing is required
- C. high starting torque is needed
- D. all above features are required
Explanation
A slip-ring motor permits external rotor resistance, giving high starting torque and useful speed control, including controlled starting and reversal. Thus it is suitable where all the listed features are required.
