Q. Calculate the stator input current?
The parameters of the equivalent circuit shown in Figure for a three-phase, wye-connected, 220-V, 10-hp, 60-Hz, six-pole induction motor are given in ohms per phase referred to the stator:
R1 = 0.3, R2 = 0.15, Xl1 = 0.5, X'12 = 0.2, and Xm = 15.
The total friction, windage, and core losses can be assumed to be constant at 400 W, independent of load. For a per-unit slip of 0.02, when the motor is operated at rated voltage and frequency, calculate the stator input current, the power factor at the stator terminals, the rotor speed, output power, output torque, and efficiency.
