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

In an induction motor, rotor speed is always

		Less than the stator speed.
		More than the stator speed.
		Equal to the stator speed.
		None of these.
