A three-phase, 460-V, 60-Hz, four-pole Y-connected induction motor has the following equivalent circuit parameters: R, = 0.42 0, R', = 0.23 0, Xs = X', = 0.82 Q, and Xm = 22 0. The rotor speed is 1750 rpm. a. Use the approximate equivalent circuit in Figure Q2 to construct an appropriate forward motoring torque – angular speed characteristic graph for the induction motor. The graph must at least have the following points: i. Torque at synchronous speed and its corresponding slip. ii. Torque at stationary and its corresponding slip. ii. Maximum torque and its corresponding slip. iv. Torque at 1750 rpm and its corresponding slip.
