  • Patent number: 9467010
    Abstract: A method of inserting a continuous conductor having a rectangular cross-section into slot segments formed in a stator core includes forming a core member having a plurality of slot segments each having an opening and inserting a stator winding having a plurality of phases into select ones of the slot segments. Each of the plurality of phases has at least one conductor including a plurality of substantially straight segments alternately connected by a plurality of end loop segments. A section of the at least one conductor includes three consecutive end loop segments and three consecutive straight segments formed from a single continuous conductor. The method further includes narrowing the opening of each of the plurality of slot segments by forming an annular stator core having a central axis. The three consecutive straight segments are substantially similarly radially spaced from the central axis.

  • Patent number: 8745847
    Abstract: A method of P-forming a conductor having a rectangular cross-section to create a continuous stator winding. The method includes forming a conductor having a rectangular cross-section into a series of first and second substantially parallel segments that meet at a vertex, deforming the conductor such that each of the first and second segments are non-parallel to form a cross-over feature at the vertex, and deforming a section of each of the first and second segments to include corresponding first and second portions that are generally parallel to create the continuous stator winding.

  • Patent number: 8327677
    Abstract: A twisting device comprises at least one conductor coupler configured to engage a plurality of the conductors and at least one drive operably connected to the conductor coupler. The at least one drive is configured to rotate the conductor coupler in order to bend the plurality of the conductors and simultaneously move the conductor coupler in an axial direction relative to the electric machine component. An associated method of bending conductors positioned in a component of an electric machine comprises first engaging a plurality conductors with a conductor coupler. Thereafter, the plurality of conductors are bent by rotating the conductor coupler while simultaneously moving the conductor coupler in an axial direction relative to the component of the electric machine.

  • Publication number: 20110072652
    Abstract: A winding apparatus includes a mounting fixture configured to support a plurality of stator teeth. The mounting fixture is configured to rotate about an axis defined by each of the plurality of stator teeth. A plurality of stator tooth holding elements are connected to the mounting fixture. The plurality of stator tooth holding elements retain a select one of the plurality of stator teeth relative to the mounting fixture. The mounting fixture is selectively rotated about the central axis of at least one of the plurality of teeth to apply wraps of wire to the one of the plurality of stator teeth while at the same time rotating others of the plurality of stator teeth. A wire guiding member is supported by the mounting fixture.
