Machine for winding dynamo-electric stators

A method of forming field coils on a stator for a dynamo-electric machine, said stator including a plurality of slots defined by stator teeth, the method including the steps of:

• providing a winding tool and a winding tool driver for actuating said winding tool in reciprocating movement relative to a stator;
• providing a drifting tool and a drifting tool driver for actuating said drifting tool in reciprocating movement for engaging and forming wire within a slot in said stator;
• actuating said winding tool driver to move said winding tool relative to said stator while feeding wire from a wire feed passage on said winding tool into a slot in said stator;
• and
• actuating said drifting tool driver simultaneously with said step of actuating said winding tool driver for moving said drifting tool relative to said stator to form said wire in said slot at the same time as said wire is fed into said slot by said winding tool.

An apparatus for forming field coils on a stator for a dynamo-electric machine, said stator including a plurality of slots defined by stator teeth, said apparatus comprising:

• a stator mount for supporting a stator;
• a winding tool defining a longitudinal axis and extending in a first direction for movement through said stator mount, said winding tool including a wire feed passage for feeding wire into slots of a said stator supported by said stator mount;
• a drifting tool extending in a second direction opposite said first direction and including at least one radially extending drifting blade for extending through a slot in said stator;
• said drifting tool including a longitudinal axis aligned with said longitudinal axis of said winding tool;
• and
• said winding tool and said drifting tool each supported for simultaneous movement in the same longitudinal direction to perform a wire forming operation at the same time as wire is fed into said slots of said stator.
