D.C. motor is to drive a load which has certain minimum value for most of the time and some peak value for short duration. We will select the________________?
Correct answer: A. series motor
- A. series motor
- B. shunt motor
- C. compound motor
- D. any of the above
Explanation
A series motor is suitable when the load remains present but periodically reaches a high peak, because its series field provides high torque during the peak demand. It must not be operated at truly no load because of possible overspeed.
