In D.C. motor which of the following can sustain the maximum temperature rise?
Correct answer: C. Field winding
- A. Slip rings
- B. Commutator
- C. Field winding
- D. Armature winding
Explanation
The field winding is stationary and generally has better heat dissipation than the rotating armature and commutator assembly. It can therefore tolerate the greatest temperature rise among the listed parts.
