Abstract
Coil winding and placer equipment arranged on an indexing table and rotatable between coil winding and coil insertion stations. Coils are wound on a coil winding form by means of a flyer and are stripped from the coil form onto an array of pivotable coil retainers. The coil retainer array is arranged outside of and concentrically with the coil insertion blades whereby the coil retainer array retains a complete set of stator coils. A stator core is positioned above the placer equipment and the retainers are pivoted inwardly thereby releasing the complete set of coils which are now held only by the insertion blades. The blades are moved upwardly into the bore of the stator core and a coil stripper is actuated to insert the coils into the axial slots of the stator core.
