Q1) A 460-V, 25-hp, 60-Hz, four-pole, Y-connected induction motor has the following impdances in ohms per phase referred to the stator circuit: R1 = 0.641 Q, X1 = 1.106 N, R2'=0.332 N, X2' = 0.464 2, Xo = 26..3 Q The total rotational losses are 1100 Wand are assumed to be constant. The core loss is Jumped in with the rotational losses. For a rotor slip of 2.2 percent at the rated voltage and rated frequency, find the motor's 1) Input current & Efficiency 2) Sketch the complete torque-speed characteristic of an induction machine and indicate the three modes of oneration

Suppose the current in this circuit is I = -35 A. The voltage drop across each circuit element is as given in the table below. From this information, determine, for each of these circuit elements, (i) whether an active or passive sign convention is being used for that element, (ii) whether that element is absorbing or producing a net (positive) amount of electrical power. In each answer box within the table below, type the correct choice from among the bold-faced words above. - A A B C A + с B + V₂ Circuit element Voltage drop Sign convention? Absorbing or producing net electrical power? -5 V -6 V 1 V -
