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