Question 1 A 3-phase, 440-V, delta-connected, 4-pole 50-Hz induction motor runs at a speed of 1447 rpm when operating at its rated load. The equivalent circuit has the following per-phase :parameters r1=0.2 N, x1-x2=2 Ω, r2-0.4 Ω, rc=200 Ω, χφ 40 Ω %3D Using the approximate circuit, determine, for rated load, the values of line current and power factor, torque, output power and efficiency. The mechanical loss is 1000 watts.
