Abstract
An apparatus for forming wire coils on a stator including a winding tool movable in reciprocating and rotating movement and including wire apertures for feeding wire into slots of a stator. A drifting tool is provided adjacent an end of the winding tool and includes drifting blades extending radially outwardly for positioning within the slots of the stator. The drifting tool is movable with the winding tool during the winding operation such that the drifting tool follows the winding tool in its reciprocating movement to provide for displacement of wire in the slots and improve the slot fill during the winding operation. Wire retaining structures are provided above and below the stator to intermittently engage and retain wire located at the ends of the stator. A wire feed mechanism is also provided including a wire feed pulley and a belt cooperating with the pulley to push wire toward the winding tool. The wire feed pulley includes a groove, and a wire exit member is provided cooperating with the groove to engage with ends of wire located in the groove and direct the wire into a passage extending to the winding tool.
