Abstract
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.
