Concept explainers

Single Phase Induction Motor

The single-phase induction motor or engine consists of a single rotating phase in the stator and a rotating cage in the rotor. When phase one supply is connected to the stator winding, a magnetic field is generated. In the pulsating field, the rotor does not rotate due to inertia. So, a single-phase import motor does not start and requires some initial methods.

Question

When all of the resistance is removed from the rotor of a wound-rotor motor, the phase angle is at its ________ and the motor behaves like a standard induction motor.

a. Minimum

b. Maximum

c. Midpoint

d. Saturation point
