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.

Example -6.
A three-phase, 60-Hz, four-pole induction motor runs at a no-load speed of 1790
r/min and a full-load speed of 1720 r/min. Calculate the slip and the electrical
frequency of the rotor at no-load and full-load conditions. What is the speed
regulation of this motor?
