A three-phase, Y-connected, 460 V, 1740 rpm, 60 Hz, 4-pole, wound-rotor induction motor, has the following parameters per phase referred to the stator side as shown in the given figure: Nr = 1740 rpm R 0.25 , R = 0.20 2, = Vin X = 0.5 0, X = 0.5 0, Xm = 30 R1 JX1 R2 JX2 ww jXm R Per phase IEEE equivalent circuit of three-phase induction motor (referred to stator side) The rotational losses are 1700 watts. With rotor terminals short- circuited, find the followings: a. Value of R3 at rated conditions. b. Starting current when started directed on full voltage. c. Starting torque. d. Full-load slip. e. Full-load current. f. Full-load power factor. g. Full-load torque. h. Motor efficiency at full load. i. Slip at which maximum torque is developed. j. Maximum torque developed. k. Draw the torque-speed characteristics of the induction motor. Show on your drawing the followings: starting, maximum & full rated torques with their corresponding slips.
