Stator designs have wide-mouth slots between adjacent poles. Wire coils with high slot fill conductivity are formed around the poles. In some designs, the wire coils are wave wound around the poles. Thick bar conductors can be used for making the wire coils. The wire coils may be inserted using nozzle dispensers or transferred from a pre-form mandrel. In other designs, the wire coils are pre-formed on transferable pockets that are then mounted on the poles.

Method of winding a dynamo-electric machine component

The present invention concerns forming wire coils by simultaneously winding a plurality of wires onto a dynamo-electric machine component. In order to maximize the amount of wire that can be placed in the spacings of the dynamo-electric machine component, the turns of the wire coil must be regularly disposed without twisting the plurality of wires onto each other. Current winding apparatus may allow certain portions of the wire turns to unevenly accumulate and locally bulge outward from the collection of wire coils. Such bulges, especially in consideration of the limited spacings available on an dynamo-electric machine component, may interfere with or access to the spacings by a wire dispensing member during the winding process. The present invention proposes to perform multiple-wire winding processes that avoid wire twisting and improper disposition of the wires. Further, the present invention proposes to improve the ability of the wire dispensing member to traverse the spacings on the component. As a consequence, the winding processes performed with the present invention are less likely to be hindered by interference and are capable of obtaining more wire fill within the component spacings and higher winding speeds.

In accordance with the present invention, none of the plurality of wire coils may surmount a first portion of the wire lead anchored at the location. In some embodiments, a template for winding the wire coils may be provided that has a seat portion on the underside of the template. The seat portion may receive a wire lead such that the lead is aligned with the anchoring location on the insertion tool.

Apparatus and methods for winding wire coils for dynamo-electric machine components

A winder for winding wire onto coil supports of dynamo-electric cores with translational, rotational, and stratification motions with respect to a central longitudinal axis of the dynamo-electric core is provided. The rotational motion may preferably be provided by the rocking motion of a gear sector. The stratification motion may preferably be provided by the implementation of a spiral groove. The spiral groove preferably shares the same longitudinal axis as the winder. The rotation of the spiral groove preferably creates a relative motion between the groove and the needles, thereby producing the radial stratification motion of the needles. Additionally, the winder includes a motor arrangement which is programmable and controllable. The motor arrangement may also provide a dampening effect to limit unwanted stratification motion.

The present invention concerns solutions for disposing the wire leads of a wire coil along trajectories that have predetermined positional references relative to the dynamo-electric machine component. The present invention proposes to provide a wire lead manipulator that operates to dispose the wire lead by entering within extremely narrow gaps on a dynamo-electric machine component at high speed and with a lower risk of the wire lead manipulator colliding with the accessory parts of the component. Using the solutions of this invention, these achievements are possible for dynamo-electric machine components with very small spaces between accessory components that do not allow the passage of conventional wire lead manipulator apparatus.

Wire manipulator methods and apparatus for dynamo-electric machine coil winding

The present invention is concerned with the driving mechanism of winding needles which dispense wire to form the wire coils of a dynamo-electric machine component. Generally, such wire winding is achieved by providing translational, rotational, and radial motions to the winding needle relative to a reference structure of the component. The present invention provides wire winding solutions for causing the winding needles to accomplish predetermined motions with respect to the component so that wire is predictably positioned on the component to form the wire coils. In particular, the present invention provides a driving mechanism with coaxial hollow shafts that impart the necessary motions to the winding needle. In one aspect of the invention, the inner shaft is able to mirror the rotation of the outer shaft to provide rotational motion to the winding needle. In another aspect of the invention, the outer shaft is able to impart both translational and rotational motion via coaxially disposed rotatable sleeves driven by motors. In yet another aspect, all of the winding motions are coordinated using a programmable control mechanism.

Dynamo-electric core winder

An improved needle solution is provided for winding wire coils onto dynamo-electric machine components such as electric motor stators and armatures. The improved needle solution decreases the opportunity for collision between the needle apparatus and the machine component onto which wire coils are being wound and enables the winding of machine components with small interior hollows that may not allow conventional needle solutions to pass through. The improved needle solution further provides increased accuracy in wire coil stratification by stabilizing the stratification motion of the apparatus using guide structures that engage the needle arm. The needle solution further provides open access to the wire being fed through the apparatus for winding onto the machine component. Multiple needles may be accommodated by the apparatus to simultaneously wind multiple wire coils onto a machine component using the improved needle solution.
