Methods and apparatus are provided for generating and connecting an intermediate lead wire extending between multiple portions of a coil wound on a pole of a stator core to a slotted terminal mounted on the stator core. Such stator cores, wound by coil winding shuttles, are used in electric motors, generators and similar devices. An intermediate lead wire extending between multiple portions of a coil is first captured by a hook mechanism, aligned with a slotted terminal, and then inserted in the terminal by a wire insertion device. The wire is then held in engagement with the terminal while the next portion of the coil is begun, producing an intermediate lead wire connection wherein a first portion of the lead wire is engaged within a slot in the terminal and the portion extending from the terminal to the next coil portion is wrapped tightly against the exterior of the terminal. In accordance with the principles of this invention, no cutting of the intermediate lead wire is required.

Methods and apparatus are provided for connecting a lead wire extending from a coil portion wound on a pole of a stator core to one or more terminals mounted on the stator core, wherein the method includes the steps of: grasping a lead wire; disposing the lead wire adjacent at least a first terminal; partially and then fully engaging the lead wire with the terminal; repeating the steps of disposing and engaging the lead wire with later terminals, if any; and then cutting the lead wire. Apparatus is provided for performing the method steps for complex lead wire connection patterns.

Methods and apparatus for winding stators (e.g., electric motor stators) so that the ends of each coil can be terminated at respective opposite ends of the stator. The coil wire is anchored adjacent a first end of the stator. Then the coil supply means is alternately reciprocated longitudinally along and rotationally about the longitudinal axis of the stator to wind the wire on the stator. When the desired number of windings has been applied, the wire supply means is stopped adjacent the second end of the stator and the wire is anchored adjacent that end of the stator. The wire is then cut between the second anchoring point and the wire supply means, and the wire supply means is returned to the starting position to prepare for winding the next stator.

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.

Methods and apparatus for insulating interior walls of lamination slots of dynamo-electric machine components are provided. The relative speeds and sequence of cutting, forming, and inserting a piece of insulation material into the slot of the lamination core of a dynamo-electric machine component may be determined by a central drive mechanism. The central driving mechanism may have a plurality of cams, rotating with a main shaft, to control the translations of cutting, forming and inserting members.

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.

Insulating strip material for dynamo-electric machine parts (e.g., for armature core slot liners) is fed out intermittently by a reciprocating assembly which releasably clamps the strip material during at least a portion of the assembly's stroke in one direction. The material that has been fed out is cut off, formed into the desired shape (if necessary), and inserted into the dynamo-electric machine part during further motion of the reciprocating assembly.
