Abstract
A device for placing prewound coils into stator slots comprises an annular series of fingers housed in respective longitudinal grooves of the outer surface of a hollow cylindrical finger holder. The fingers project beyond one end of the holder for placement thereon of prewound coils. A stripper member axially movable through the stator is provided on its periphery with a series of longitudinal grooves wherein the portion of each finger which projects beyond the holder is received. Some fingers, and preferably at least one finger of each couple of adjacent fingers between which a prewound coil is interposed is slidably mounted both within said stripper member and within said holder.
Claims5
A device for placing prewound coils in the slots of a stator comprising:
- a fixed hollow cylindrical finger holder having a series of longitudinal grooves on its periphery;
- an annular series of fingers around said holder, each finger being received in one of said grooves, said fingers projecting beyond one end of said holder for placement thereon of prewound coils;
- stripper means axially slidable within the annular series of fingers and through a stator for driving coils over said fingers and into the slots of the stator, said stripper means being comprised of a stripper member having in its periphery a plurality of longitudinal grooves, each finger being received in one of said grooves of the stripper member, at least one finger of each couple of adjacent fingers between which a coil is interposed being slidably mounted with regard to said stripper member and being also mounted for axial sliding movement with said holder for a distance at least equal to the distance of movement of the stripper.
