Locked rotor current of a shaded pole motor is____________?
Correct answer: C. slightly more than full load current
- A. equal to full load current
- B. less than full load current
- C. slightly more than full load current
- D. several times the full load current
Explanation
A shaded-pole motor has relatively high leakage impedance, which limits its locked-rotor current; it is therefore only slightly greater than the full-load current. This is consistent with its low starting torque and modest efficiency.
