Abstract
A rotor of a wound rotor motor/generator comprising a plurality of rotor windings including a line rotor coil and a star rotor coil. The rotor coil couples to an L-conductor having an L-shaped profile such that a portion of the L-conductor extends from the line rotor coil toward the star rotor coil. A line connector bar couples the L-conductor to a rotor lead such that the line rotor coil is electrically coupled to the rotor lead. The star rotor coil couples to an L-support having an L-shaped profile such that a portion of the L-support extends from the star rotor coil toward the line rotor coil. An insulator is positioned between the L-conductor and the L-support to electrically insulate the L-support from the L-conductor. Lastly, an insulating rope couples the L-conductor to the L-support.
