Abstract
A coil forming and insertion apparatus includes plural coil winding frames, a winding jig for forming a multipole coil, plural coil receiving portions, and an inserter jig for inserting and arranging the multipole coil in slots of a stator core. The coil forming and insertion apparatus has each coil receiving portion opposed to a coil winding frame, the multipole coil is formed by connecting the monopole coils wound on the coil winding frames and the multipole coil is transferred from the winding jig to the inserter jig.

A coil forming and insertion apparatus comprising:
- a winding jig for forming a multipole coil of joined plural monopole coils, said winding jig comprising plural coil winding frames, each of said coil winding frames defining a winding axis and receiving loops of wire wound thereon to form one of said plural monopole coils;
- an inserter jig opposed to said winding jig, for inserting and arranging the multipole coil into a slot extending radially outward from a central opening in a stator coil, said inserter jig comprising plural coil receiving elements for respectively receiving the monopole coils from said coil winding frames, each of said coil receiving elements being aligned with a coil winding frame;
- and
- transfer means for transferring each monopole coil from said winding jig to said inserter jig.
A coil forming and insertion apparatus comprising:
- a winding jig, rotatable around a central axis, for forming a multipole coil of joined plural monopole coils, said winding jig comprising plural coil winding frames, each of said coil winding frames defining a winding axis and receiving loops of wire wound thereon to form one of said plural monopole coils, wherein said winding axes are approximately parallel to each other and equidistant from said central axis;
- an inserter jig opposed to said winding jig and comprising:
- plural slidable cores, respectively aligned with each winding axis, for inserting and arranging the multipole coil into a slot extending radially outward from a central opening in a stator;
- and
- coil receiving elements arranged around an outer circumference of each slidable core for connecting with respective coil winding frames to form a transfer surface for transfer of the monopole coils from said coil winding frames onto said coil receiving elements, said slidable cores being extendable to transfer a monopole coil from a coil receiving element into the slot in the stator.
A coil forming and insertion method utilizing a winding jig having plural winding frames for forming a multipole coil and an inserter jig for inserting and arranging the multipole coil in a slot extending radially outward from a central opening in a stator core, said method comprising:
- winding an electric wire around each of the plural coil winding frames to form plural monopole coils connected as a mutipole coil;
- and
- simultaneously transferring the plural monopole coils from said winding frames onto coil receiving elements of said inserter jig.
A coil forming and insertion method comprising:
- winding an electric wire into loops around each of plural coil winding frames of a winding jig to form a monopole coil on each of the winding frames, with the monopole coils joined together in a circular array as a multipole coil, wherein the coil winding frames are approximately parallel to each other;
- inserting plural coil receiving elements, surrounding a core mounted on the inserter jig for axial sliding movement relative to the receiving elements, into a central opening in each monopole coil mounted on a coil winding frame and thereby connecting with the coil winding frame to form a transfer surface;
- transferring the monopole coils along the transfer surfaces, from the winding jig onto to inserter jig;
- and
- advancing the cores of the inserter jig to insert the multipole coil into a slot in a stator.
