Problem # 3: Induction Motor Analysis [35 points]
(a) A three-phase, two- pole, 50hp, 500V (line-line), 60Hz, wye-connected, wound-rotor
induction motor has the following per-phase parameters
$R_1 = 0.64 \text{ Ohm}$,
$R_2 = 0.332 \text{ Ohm}$
$X_1 = 1.06 \text{ Ohms}$,
$X_2 = 0.464 \text{ Ohm}$,
$X_m = 75 \text{ Ohms}$,
$R_c = 1000 \text{ Ohms}$
1. Determine the parameters of the per phase Thevenin equivalent circuit of the motor.
Draw the Thevenin equivalent circuit and give the values of the parameters on the
diagram of the equivalent circuit [10 points]
