A 500-hp, wye-connected, wound-rotor induction motor, when operated at rated voltage and frequency, develops its rated full-load output at a slip of 0.02; maximum torque of 2 times the full-load torque at a slip of 0.06, with a referred rotor current of 3 times that at full load; and 1.2 times the full-load torque at a slip of 0.2, with a referred rotor current of 4 times that at full load. Neglect rotational and stray-load losses. If the rotor-circuit resistance in all phases is increased to 5 times the original resistance, determine the following:
(a) The slip at which the motor will develop the same full-load torque.
(b) The total rotor-circuit copper loss at full-load torque.
(c) The horsepower output at full-load torque.
(d) The slip at maximum torque.
(e) The rotor current at maximum torque.
(f) The starting torque.
(g) The rotor current at starting.
Explain the Construction of Synchronous Machines? Basically all synchronous machines require a DC excited field winding in order to produce magnetic flux. For majority of machi
