A three-phase, eight-pole induction machine has equivalent two-phase parameters Rs = 60 Ω, Rr = 50 Ω, Ls = 9.27 mH, Lr = 9.25 mH, and M = 9 mH. The machine is being driven by an RMS line current of 30 A at a frequency of 60 Hz. The angular velocity of the rotor is 950 rpm. Determine a) the mechanical torque, and b) the line-line RMS voltage.
