Method of winding a stator core with a continuous conductor having a rectangular cross-section and a stator core
A method of inserting a continuous conductor having a rectangular cross-section into slot segments formed in a stator core includes deforming in a first direction a core member having a first end portion that extends to a second end portion to widen an opening at end portions of the slot segments, inserting one or more continuous conductors having a rectangular cross-section into select ones of the slot segments, and deforming in a second direction the core member to narrow the opening at end portions of the slot segments.
1. A method of inserting a continuous conductor having a rectangular cross-section into slot segments formed in a stator core, the method comprising:
deforming in a first direction a core member having a first end portion that extends to a second end portion to widen an opening at end portions of the slot segments;
inserting one or more continuous conductors having a rectangular cross-section into select ones of the slot segments; and
deforming in a second direction the core member to narrow the opening at end portions of the slot segments.
2. The method of claim 1 , further comprising: joining the first end portion of the core member to the second end portion of the core member to form an annular stator core.
3. The method of claim 1 , wherein widening the opening includes separating tooth elements provided on the end portions of the slot segments.
4. The method of claim 1 , wherein deforming in the first direction establishes a convex curvilinear surface defined by the end portions of the slot segments between the first end portion and the second end portion of the core member.
5. The method of claim 1 , wherein deforming in the second direction establishes a concave curvilinear surface defined by the end portions of the slot segments between the first end portion and the second end portion of the core member.
