Athree-phase,wye-connected, 220-V, 10-hp, 60- Hz, six-pole inductionmotor (using Figure 13.2.6 for notation) has the following parameters in ohms per phase referred to the stator: R1 = 0.294, R 2 = 0.144, Xl1 = 0.503, X 12 = 0.209, and Xm = 13.25. The total friction, windage, and core losses can be assumed to be constant at 403W, independent of load. For a slip of 2.00%, compute the speed, output torque and power, stator current, power factor, and ef?ciency when the motor is operated at rated voltage and frequency. Neglect the impedance of the source.
Find the resonant frequency: Find the resonant frequency ω0 (or f0) for the given series RLC circuit v = Vm sin ωt = 50 sin ωt Figure Also determine the expre
