ELECTRIC MACHINE STATOR WINDING LEAD CONNECTIONS
Stators for use in electric machines and methods for refurbishing the same. One method for refurbishing a stator for use in an electric machine includes at least partially disassembling the stator to provide access to a plurality of stator windings connected in a four-circuit star connection having three turns per coil, and reconfiguring the stator such that the plurality of stator windings are connected in a four-circuit delta connection having five turns per coil.
1 . A method for refurbishing a stator for use in an electric machine, the method comprising:
at least partially disassembling the stator to provide access to a plurality of stator windings, wherein overhang portions of the plurality of windings are connected via one or more braze joints;
removing the one or more braze joints; and
connecting the overhang portions of the plurality of windings directly to a generator terminal.
2 . The method of claim 1 , wherein connecting the overhang portions includes bolting the overhang portions of the plurality of windings directly to the generator terminal.
3 . The method of claim 1 , wherein the overhang portions of the plurality of windings are connected directly to the generator terminal without any brazing.
