The range of efficiency for shaded pole motors is______________?
Correct answer: D. 5% to 35%
- A. 95% to 99%
- B. 80% to 90%
- C. 50% to 75%
- D. 5% to 35%
Explanation
Shaded-pole motors have high rotor losses and weak starting torque, so their efficiency is very low, commonly about 5% to 35%. The higher ranges are typical of more efficient induction motors.
