Methods and apparatus for winding wire coils on cores of dynamo-electric machine components such as stators and alternators are provided. The apparatus may be used to wind wire coils on the poles of a stator. The apparatus includes a movable wire dispenser and a set of wire pullers. The wire pullers are used to form a loop in an initial stretch of wire dispensed by the wire-dispenser alongside a stator pole. The loop is first formed adjacent to the pole and then moved above the pole out of the paths of subsequent wire stretches dispensed to form the wire coils. The loop may be pulled taut in either direction upon completion of the winding operation to connect the wire to a terminal.

Dynamo-electric machine stator winder methods and apparatus with loop-forming wire pullers

In a dynamo-electric machine, a stator having a terminal board with at least one pair of slots located along its inside circumference, includes at least one pair of coil holders. Each coil holder is cantilevered from the terminal board at the ends of a pair of slots, and a wire guide is positioned on each coil holder. A wire depositing needle and the stator are placed in relative motion, which causes the guide to support the wire as it is transported along its surface. Coils of wire are created as each pair of slots is wound. The invention will typically be used to form multiple coil windings on a single stator.

Wire guide for winding dynamo-electric machine stators without shrouds

The present invention discloses methods and apparatus for winding successive differently sized components with coils of wire. More specifically, the present invention is directed to methods and apparatus for winding multiple electric motor armatures in succession, when those armatures have different dimensions. Generally speaking, the invention includes an assembly with movable parts, which enables all armatures to have a common alignment characteristic in the winding apparatus. If necessary, the actual coil winding mechanism will shift to achieve proper positioning relative to each armature. This reduces the number of adjustments that have to be made to hardware that is ordinarily required to wind such differently sized armatures.
