Abstract
Dynamo-electric machine armatures which have commutators and cores that are axially close to one another are wound with the aid of wire guiding hooking plates that are inclined to reach into the portion of the commutator that is axially adjacent to the core where the coil leads must be attached to the commutator. The hooking plate may also perform an additional extension motion in order to press the coil leads out of the way of a subsequent fusing operation. This function may alternatively be performed by a separate pusher member which is either associated with the hooking plate or independent of the hooking plate. The fusing electrode may be specially shaped to facilitate performing fusing operations axially close to the armature core.

Apparatus for winding coils of wire on a dynamo-electric machine armature having a shaft, a core mounted concentrically on said shaft, and a commutator mounted concentrically on said shaft adjacent to said core, said core having a plurality of axially extending slots cut radially into its outer periphery, and said commutator having a plurality of coil lead anchoring structures adjacent to said core, said apparatus comprising:
- a flyer having a wire dispensing outlet that is rotatable about a flyer axis that is substantially perpendicular to said shaft adjacent to said core;
- a wire guide for guiding wire dispensed from said outlet to a pair of said slots;
- and
- a hooking plate that is reciprocable along a hooking plate axis that is inclined relative to both said shaft and a plane perpendicular to said shaft for guiding wire from said outlet to a coil lead anchoring structure when said hooking plate is reciprocated toward said armature.
Apparatus for winding coils of wire on a dynamo-electric machine armature having a shaft, a core mounted concentrically on said shaft, and a commutator mounted concentrically on said shaft adjacent to said core, said core having a plurality of axially extending slots cut radially into its outer periphery, and said commutator having a plurality of coil lead anchoring structures adjacent to said core, said apparatus comprising:
- a flyer having a wire dispensing outlet that is rotatable about a flyer axis that is substantially perpendicular to said shaft adjacent to said core;
- a wire guide surface for guiding wire dispensed from said outlet to a pair of said slots;
- and
- a wire guiding member extendable from said wire guide surface toward a coil lead anchoring structure along an axis that is inclined toward said shaft in a direction along said shaft from said commutator to said core for guiding wire from said outlet to said coil lead anchoring structure when said wire guiding member is extended toward said coil lead anchoring structure.
The method of winding coils of wire on a dynamo-electric machine armature having a shaft, a core mounted concentrically on said shaft, and a commutator mounted concentrically on said shaft adjacent to said core, said core having a plurality of axially extending slots cut radially into its outer periphery, and said commutator having a plurality of coil lead anchoring structures adjacent to said core, said method comprising the steps of:
- shielding said coil lead anchoring structures;
- rotating a wire dispenser about a wire dispenser axis that is substantially perpendicular to said shaft adjacent to said core;
- guiding wire from said rotating wire dispenser into a pair of said slots;
- after a coil of wire has been deposited in said pair of slots, unshielding a coil lead anchoring structure;
- extending a hooking plate toward said coil lead anchoring structure along a hooking plate axis that is inclined relative to said shaft and a plane perpendicular to said shaft so that said hooking plate guides wire from said rotating wire dispenser into said coil lead anchoring structure;
- and
- after wire has been deposited in said coil lead anchoring structure, retracting said hooking plate and re-shielding said coil lead anchoring structure.
The method of winding coils of wire on the core of an armature for a dynamo-electric machine and attaching leads from said coils to coil lead anchoring structures on a commutator of said armature, said core and said commutator being mounted axially adjacent to one another on a central shaft of said armature, a wire guide surface being used to guide wire from a wire source to said core, said method comprising the steps of:
- extending a wire guiding member toward a lead anchoring structure to deflect wire from said wire guide surface into said lead anchoring structure;
- and
- extending a pusher member into the region between said lead anchoring structure and said core to deflect wire extending between said core and said lead anchoring structure radially inwardly toward said shaft and axially toward said core.
Apparatus for winding coils of wire on a dynamo-electric machine armature having a shaft, a core mounted concentrically on said shaft, and a commutator mounted concentrically on said shaft adjacent to said core, said core having a plurality of axially extending slots cut radially into its outer periphery, and said commutator having a plurality of coil lead anchoring structures adjacent to said core, said apparatus comprising:
- a flyer having a wire dispensing outlet that is rotatable about a flyer axis that is substantially perpendicular to said shaft adjacent to said core;
- a wire guide for guiding wire dispensed from said outlet to a pair of said slots, said wire guide having a generally convex wire guiding surface with a concave recess for receiving a portion of the periphery of said core which is between said pair of slots;
- and
- a hooking member selectively extendable toward a coil lead anchoring structure through an aperture in said generally convex wire guiding surface at a location that is spaced from said concave recess to guide wire from said outlet to said coil lead anchoring structure when said hooking member is extended toward said coil lead anchoring structure.
