For the same H.P. rating and full load speed, following motor has poor starting torque_____________?
Correct answer: C. differentially compounded
- A. shunt
- B. series
- C. differentially compounded
- D. cumulativelyc'ompounded
Explanation
A differentially compounded motor has series flux opposing the shunt flux, so its resultant flux and starting torque can be low. Series and cumulatively compounded motors normally provide stronger starting torque.
