Which D.C. motor has got maximum self relieving property ?
Correct answer: A. Series motor
- A. Series motor
- B. Shunt motor
- C. Cumulatively compounded motor
- D. Differentially compounded motor
Explanation
A series motor has the strongest automatic speed response to load changes: increased load current strengthens its flux and reduces speed, while reduced load causes speed to rise. This is known as its self-relieving property.
