Calculate voltage and frequency, Electrical Engineering

Assignment Help:

The stator and rotor of a three-phase, 440-V, 15-hp, 60-Hz, eight-pole, wound-rotor induction motor are both connected in wye and have the following parameters per phase: R1 = 0.5 , R2 = 0.1 , Xl1 = 1.25 , and Xl2 = 0.2 . The magnetizing impedance is 40and the core loss impedance is 360 , both referred to the stator. The ratio of effective stator turns to effective rotor turns is 2.5. The friction andwindage losses total 200 W, and the stray-load loss is estimated as 100 W. Using the equivalent circuit, calculate the following values for a slip of 0.05 when the motor is operated at rated voltage and frequency applied to the stator, with the rotor slip rings short-circuited: stator input current, power factor at the stator terminals, current in the rotor winding, output power, output torque, and ef?ciency.
