The ratio of starting torque to full-load torque is least in case of____________?
Correct answer: B. shunt motors
- A. series motors
- B. shunt motors
- C. compound motors
- D. none of the above
Explanation
A shunt motor has nearly constant flux and comparatively low starting torque, while series and compound motors develop higher starting torque. Therefore, its starting-torque to full-load-torque ratio is the least.
