The équivalent circuit parameters of a 15-V, 50- Hz, 4-pole, Y-connected, three-phase induction motor in ohms/phase are R, = 0.20, X, = 0.70, R2 = 0.25, Xm = 400. X, = 0.50, and %3D (a) The slip s, at which the motor develops maximum torque. (b) The maximum torque developed Tam by the motor. (c) The motor speed Wm- (d) The corresponding power developed Pa. If the rorot restsnce is trippled (R,'=3*R,), find (e) The new slip sp3 at which the motor develops
