A three-phase, 335-hp, 2000V, six pole, 60 Hz, Y-connected squirrel-cage induction motor has the following parameters per phase that are applicable at normal slips: = 0.292. x = x2 = 0.70792, r =0.203. rc = 450 Xo = 779 The rotational losses are 4100 watts. Using the approximate equivalent circuit, compute for a slip of 1.5%. a. the line power factor and current. b. developed torque. c. efficiency. (8+4+4)
