A 75-hp, 460-V, 4-pole, 60-Hz, Y-connected induction motor develops its full-load
induced torque at 3% slip when operating at 460 V. The motor has the following per-phase
equivalent parameters referred to the stator side:
R₁
X₁
=
=
0.07 Ω
0.35 Ω
Xm = 200
X2 = 0.35 Ω
The mechanical, core and stray losses represent 5% of the rated output power. Use the
approximate circuit model (without Rc) to
a) Find R₂ (i.e., referred to the stator side)
b) Calculate Tmax, Smax, and the rotor speed at the maximum torque
