Three Phase Induction Motor

The induction motor is an electric motor that runs on AC (alternating current) and it is of two type single phase motor that work on single-phase power supply and three-phase motor that work on three-phase power supply.

Question

A 3-phase, 4 pole, 230 V, 60 Hz wound-rotor induction motor has both its stator and rotor
connected in Y. The rotor has half as many turns per phase as the stator. If the rotor is running
at 1725 rpm, Rr is 0.075 ohms and Xs = 0.375 ohms, determine the torque developed by the
motor.
