A 400V, 4 Pole, 3 Phase, 50 Hz star connected induction motor has a rotor resistance and
reactance/phase = 0.01Ω and 0.1Ω respectively and stator resistance and
reactance/phase of 0.641 and 1.106 respectively and Xm=26.3. The equivalent circuit
is referred to the stator. Determine i) Starting Torque ii) Slip at which maximum torque
will occur. iii) Speed at which maximum torque occurs iv) The value of maximum torque
v) Full load torque if full load slip is 4%. Assume ratio of stator to rotor turns as 4.
