The type of single-phase induction motor, expected to have the maximum power factor during steady state running condition, is

1. split phase (resistance start).
2. shaded pole.
3. capacitor start.
4. capacitor start, capacitor run.

Correct answer: capacitor start, capacitor run.

Solution

The capacitor start, capacitor run motor is designed to improve both starting torque and efficiency, resulting in a higher power factor during steady state operation compared to other types of single-phase induction motors.
