A 3-phase, 226-V, 50-Hz, 35 HP, 6-pole, Y-connected induction motor is operating with a line current of I, = 92L-48.5° A, for a per-unit of 0.12, and R, = 0.2 Q The total friction, windage, and core losses can be assumed to be constant at 3 KW. What are the Air-Gap power and the converted power? Select one: O a. None O b. PAG = 24.4 KW and Pcony = 21.4 KW c. PAG = 18.8 KW and Pcony = 16.5 KW O d. PAG = 21.16 KW and Pcony = 18.6 KW Clear my choice

3. A 440V 60-hp six pole 60 hz A connected induction motor has the following parameters R1=0.048 R2= 0.035 Xm= 9.50 X1= 0.33 0 X2= 0.37 0 Pcore= 600W PF&W= 350W Use the Thevenin's Equivalent circuit concept to find: (a)Vth and Zth seen by the rotor circuit (b)The slip at which maximum torque occurs (c) the value of Max/pullout Torques (d) The starting torque.
