Question: A large 3 - phase, 4 1 6 0 V , 6 0 H z , squirrel - cage induction motor draws a current of

A large 3-phase, 4160V,60Hz, squirrel-cage induction motor draws a current of 380 A and the total active power of 2600 kW when operating at full-load. The corresponding speed is accurately measured and is found to be 1188rmin. The stator is connected in wye and the resistance between two stator terminals is 0.24. The total iron losses are 28 kW and the windage and friction losses are 17 kW .
Calculate the following:
a. The power factor at full-load
b. The active power supplied to the rotor
c. The total I2R losses in the rotor
d. The load mechanical power [kW], torque [kN.m], and efficiency [%]
A large 3 - phase, 4 1 6 0 V , 6 0 H z , squirrel
