Which motor should not be started on no-load ?
Correct answer: A. Series motor
- A. Series motor
- B. Shunt motor
- C. Cumulatively compounded motor
- D. Differentially compounded motor
Explanation
A series motor must not run without load because its speed can rise dangerously when the load current and hence field flux become very small. This can cause mechanical failure through overspeed.
