The single-phase equivalent-circuit parameters for a three-phase induction motor in ohms-per-phase are
R1=0.17 R2=0.24 X1=1.05 X2=0.87 Xm=82.1 Rc=435
For a slip of 5 percent, and a terminal voltage of 460 V, line to line, calculate:
A) Calculate the motor phase current and input real and reactive power.
B) Calculate the mechanical output power and the power dissipated in the rotor. You might assume that the motor friction and windage losses are 270W
C) Calculate the motor core loss and the motor efficiency.
