Differentially compound D.C. motors can find applications requiring___________?
Correct answer: B. low starting torque
- A. high starting torque
- B. low starting torque
- C. variable speed
- D. frequent on-off cycles
Explanation
In a differential compound motor, the series field opposes the shunt field, reducing the net flux as load increases and giving comparatively low starting torque. Such motors are therefore associated with applications needing low starting torque, although their use is limited because of unstable speed characteristics.
