As -the load is increased the speed of D.C. shunt motor will____________?
Correct answer: A. reduce slightly
- A. reduce slightly
- B. increase slightly
- C. increase proportionately
- D. remains unchanged
Explanation
Increasing load increases armature current and the voltage drop in the armature circuit, slightly reducing back e.m.f. and speed. A shunt motor therefore has only a small speed decrease with load.
