  • Rotor transformer positioning mechanism and operating method therefor
    Patent number: 6891460
    Abstract: A rotor transformer positioning mechanism permitting automatic positioning of a rotor transformer, having a first winding, relative to a rotor stack, having a second winding, mounted on a common rotary shaft to thereby permit a crossover having a predetermined length to be installed between the first and second windings includes a crossover positioning cutout disposed in a first flange of the rotor transformer. In an exemplary case, the rotor transformer includes the first flange and a second flange disposed on opposite ends of the first coil, and the second flange is proximate to the crossover. A method of assembling a rotating machine using the rotor transformer positioning mechanism is also described.
