Less maintenance troubles are experienced in case of___________?
Correct answer: B. squirrel cage induction motor
- A. slip ring induction motor
- B. squirrel cage induction motor
- C. both A. and (b)
- D. none of the above
Explanation
The squirrel-cage rotor has no slip rings, brushes, or external starting equipment, so it needs less maintenance than a slip-ring motor. Slip-ring assemblies are common sources of wear and sparking.
