A 208 V, three phase, 4 pole, 25 hp motor has the following per phase parameters referred to the stator. R₁ = 0.03Ω X₁ = 0.1 Ω R₂ =0.06Ω, X₂ = 0.1 22 Ω, Xm = 4Ω
Core and friction loss 1650 W
Use an appropriate equivalent circuit to estimate the line current and power factor when the motor is running at 1725 rpm.
