The equivalent-circuit parameters of an 8-kW, 230-V, 60-Hz, four-pole, two-phase, squirrel-cage induction motor in ohms per phase are R_l = 0.253 X_l = 1.14 X_m = 32.7 R₂ = 0.446 X₂ = 1.30. This motor is operated from an unbalanced two-phase, 60-Hz source whose phase voltages are, respectively, 223 and 190 V, the smaller voltage leading the larger by 73°. For a slip of 0.045, find

a. The phase currents in each of the windings and

b. The internal mechanical power.
