(b) The parameters of the equivalent circuit for a three-phase. Y- connected. 22ov, 60HZ. six-pole induction motor are given below in ohms per phase referred to the stator: R- 0.3. R- 0.15. Xa - 0.5. X- 02. and x.- 15. The total friction, windage, and core losses can be assumed to be constant at 400 W. independent of load. If the per-unit slip is 0.02 and the motor is operated at rated voltage and frequency, determine: O The stator input current (i) The power factor at the stator terminals (ii) The power transfered across the air gap (iv) The motor rotor speed

| (b) The parameters of the equivalent circuit for a three-phase, Y- connected, 220V, 60HZ, six-pole induction motor are given below in ohms per phase referred to the stator: R = 0.3, R' = 0.15, XI 0.5. X2' = 0.2, and Xm = 15. The total friction, windage, and core losses can be assumed to be constant at 400 W, independent of load. If the per-unit slip is 0.02 and the motor is operated at rated voltage and frequency, determine: (i) The stator input current (ii) The power factor at the stator terminals (ii) The power transferred across the air gap (iv) The motor rotor speed
