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.

Mechanical strength of connection of wound rotor generator/motor

A refurbished rotor of a wound rotor machine. The refurbished rotor includes a plurality of windings assembled to the rotor core, each manufactured from two separate bars: a top coil and a bottom coil. The top coil is positioned in a rotor core slot at a position radially outward of a position of the bottom coil within another rotor core slot. Each top coil and each bottom coil has a flat rectangular cross-section. On a connection end of the rotor where rotor leads are attached, the top coil has a flat end positioned alongside and in alignment with a flat end of the bottom coil of an adjacent one of the plurality of windings. The top coil and the bottom coil have respective flat ends joined to each other on a non-connection end of the rotor opposite the connection end by a joint for establishing electrical continuity.
