A 208 V, two pole, 60 Hz, Y-connected wound rotor induction motor is rated at 15 hp. Its equivalent circuit components are
R1 = 0.2 Ω, R2 = 0.12 Ω, Xm = 15 Ω
X1 = 0.410 Ω, X2 = 0.410 Ω
The additional resistance (referred to the stator circuit) would it be necessary to add to the rotor circuit to make the maximum torque at starting conditions (when the shaft is not moving) is ____ (in ohms)Enter numerical value using the virtual keypad. Round off where necessary.
