ANSWER ONLY E, F, AND G PLEASE!!! = Please have work reflect given solutions to receive thumbs up. Thanks! a. T = 60Nm, b. I= 8.878A, c. Tst = 168.52 Nm, d. Ist = 59.4A, e. Vi=88.4V, Vi=44.2V, Vi L-L = 76.5566V, f.a T = 60 Nm, f.b 12°= 11.9194 A using Vi’, f.c T2st(new)=144.581 Nm, f.d 12 st(new)= 40.4583A, g. Pr=2.4592e+3 W. Part h. can be ignored. A three-phase, 480 V, six-pole, Y-connected, 60 Hz, 10 kW induction motor is driving a constant torque load of 60 Nm. The parameters of the motor are: R1 = 0.4 , R2 = 0.592, Xeq = 40, N1 /N2 = 2 Calculate the following: a. Motor torque. b. Motor current c. Starting torque d. Starting current A voltage is injected in the rotor circuit to reduce the motor speed by 40%. e. Calculate the magnitude of the injected voltage. f. Repeat (a) to (d) for the motor with injected voltage. g. Calculate the power delivered to the source of injected voltage. h. Determine the overall efficiency of the motor (ignore rotational and core losses).
