Question
A 3-phase, 4-pole, 37-kW, 440-V, 50-Hz,
star-connected induction motor has the
following parameters per phase: R1 =
0.10 Ω Χ1 = 0.35 Ω R'2 = 0.12 Ω Χ'2 =0.45
At no load the motor draws a line
current of 18 A at a power factor of 0.089
lagging. When the motor operates at a
slip of 2.5 %, determine (i) the input
current
