Patent ID: 7467648

Claim:
A coil forming and insertion apparatus comprising: a winding jig for forming a multipole coil of joined plural monopole coils; an inserter jig opposed to said winding jig, for inserting and arranging the multipole coil in slots extending radially outward from a central opening in a stator core, 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 the multipole coil from said winding jig to said inserter jig; and wherein said winding jig comprises: 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 a turning arm rotatable around a central turning axis and an index holder rotatably supported by the turning arm for rotation relative to the turning arm around a central axis of rotation offset from and parallel to said central turning axis; and wherein said plural coil winding frames are arranged depending from said index holder in a circular array and approximately equidistant from said central axis of rotation; wherein said winding axes of said respective coil winding frames are approximately parallel to each other and to said central turning axis; and wherein each coil winding frame is reciprocably mounted for movement along said central turning axis relative to said index holder, between a retracted position and an advanced position wherein the winding frame is projected toward said inserter jig, axially beyond the remaining coil winding frames.
