1. A rotor of a wound rotor motor/generator, the rotor comprising:
a plurality of rotor windings including a first rotor coil and a second rotor coil;
an L-conductor having an L-shaped profile and coupled to the first rotor coil such that a portion of the L-conductor extends from the first rotor coil toward the second rotor coil in a first circumferential direction;
a line connector bar coupling the L-conductor to a rotor lead such that the first rotor coil is electrically coupled to the rotor lead;
an L-support having an L-shaped profile and coupled to the second rotor coil such that a portion of the L-support extends from the second rotor coil toward the first rotor coil in a second circumferential direction, opposite the first circumferential direction, such that the L-support and the L-conductor are axially overlapped;
an insulator positioned between the L-conductor and the L-support to electrically insulate the L-support from the L-conductor; and
an insulating rope coupling the L-conductor to the L-support.
