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

Q1:- A 3-phase induction motor has an output a 37KW at this load the stator
copper loss and rotor copper loss each equal the stator iron loss. The
mechanical losses are one-third of on load loss. Calculate the slip at this
load? when efficiency = 90%
