Buses, trains, trolleys, hoists, cranes require high starting torque and therefore make use of_____________?
Correct answer: A. D.C. series motor
- A. D.C. series motor
- B. D.C. shunt motor
- C. induction motor
- D. all of above motors
Explanation
A D.C. series motor develops very high starting torque because the series field flux increases with armature current. This makes it suitable for traction and lifting loads such as trains, hoists and cranes.
