Q2 (a) A 440 V, six poles, 80 hp, 60 Hz, Y connected three phase induction motor develops its full load induced torque at 3.5 % slip when operating at 60 Hz and 440 V. The per phase circuit model impedances of the motor are R₁ = 0.32 0 XM = 32 Ω X1 = 0.44 Ω Xz = 0.38 Ω Mechanical, core, and stray losses may be neglected in this problem. Find the value of the rotor resistance R₂.
