Question

380 V, 50 Hz, 2p = 6, star connected induction motor impedance in ohms per phase values:
R1 = 0.3, X1 = j0.45, R2 = 0.15, X2 = j0.45, Xm = j15
Its total mechanical losses are 500W. Core losses are negligible. For a rotor slip of 0.01 at rated voltage, calculate the following:
1-rotor speed
2-Input active power
3-Stator copper losses
4-air gap power
5-Transferred power and Output power
6-shaft moment
7-efficiency
