The correct answer is: A. Capacitor run motor
A capacitor run motor is a type of single-phase induction motor that uses a capacitor to improve power factor. The capacitor provides a leading current that helps to offset the lagging current of the motor’s inductive load. This results in a higher power factor, which means that the motor is more efficient and uses less power.
A shaded pole motor is a type of single-phase induction motor that uses a shading ring to create a rotating magnetic field. The shading ring is a copper band that is placed around one of the stator poles. When current flows through the stator winding, it creates a magnetic field. The shading ring causes the magnetic field to be concentrated on one side of the pole, which creates a rotating magnetic field. This rotating magnetic field induces a current in the rotor, which causes the rotor to turn.
A capacitor start motor is a type of single-phase induction motor that uses a capacitor to start the motor. The capacitor provides a leading current that helps to offset the lagging current of the motor’s inductive load. This results in a higher starting torque, which makes it easier to start the motor.
A split phase motor is a type of single-phase induction motor that uses two windings to create a rotating magnetic field. The main winding is connected to the power supply, and the auxiliary winding is connected to the power supply through a capacitor. The capacitor causes the auxiliary winding to have a leading current, which helps to offset the lagging current of the main winding. This results in a higher starting torque, which makes it easier to start the motor.
In conclusion, a capacitor run motor has a relatively higher power factor than the other options.
