Abstract: A method of adjusting a stator coil lacing machine to accommodate a range of different stator stack heights which method does not require disassembly of the machine. The method utilizes a stator coil lacing machine which includes stitching means for stitching lacing cord around coils of the stator, delivering means positioned within the arbor for delivering lacing cord to the stitching means, and securing means positioned within the arbor for securing the lacing cord. The method involves orienting a stator on the arbor of the stator coil lacing machine, and adjusting the delivering means, the stitching means, and the securing means to accommodate the particular stack height of the stator. Each of these adjustments can be made without dissembling the machine.

Abstract: An automatic loader for a stator coil lacing machine includes structure for advancing a stator from a first position adjacent an arbor of the machine to a second position away from the arbor. The automatic loader also includes structure for moving the arbor between a lowered position away from the stator whereby the advancing structure moves the stator between first and second positions, and a raised position so that the stator is positioned on the arbor. The automatic loader may further include structure for disengaging a lacing cord feeder tube reciprocating drive of the machine from a cam of the machine when the arbor is lowered so the reciprocating drive is drivingly reengaged with the cam when the arbor is raised. The automatic loader may also include structure for maintaining driving engagement between a lacing needle drive of the machine and a lacing cord feeder tube oscillating drive when the arbor is raised and lowered.

Abstract: The present invention relates to a stator coil lacing machine having improved cord handling capabilities and lacing cord handling components that can be adjusted without disassembly of the machine so that the machine accommodates a range of stator stack heights.

Abstract: A method and apparatus for positioning and transferring stator coil leads in a dynamoelectric stator assembling machine. The apparatus includes holding devices for positioning and retaining the stator coil leads after the coils are wound and before they are inserted into the stator core. The apparatus also includes lead pullers for transferring the leads, during insertion of the coils into the stator core, from the inserting equipment to a stator carrying pallet having lead retaining devices herein. The apparatus further includes lead catchers for capturing the leads from the stator pallet lead retaining devices and for transferring the leads from the stator pallet to a lead finishing apparatus.

Abstract: Apparatus for placing coils and phase insulation in the slots of a dynamoelectric machine stator core member includes a core member loading and unloading station, a coil and phase insulation placing station, a preliminary end turn forming station, and a coil drifting station. An unwound core member at the loading/unloading station is loaded in mounting apparatus on a transfer arm which transfers the core to the placing station where coils and phase insulation are placed in the core member slots. The core is then transferred by the transfer arm to the preliminary end turn forming station where the end turns of the coils are formed away from the bore of the core member. The core member is then transferred by the transfer arm to the drifting station where the coils are drifted into the slots. The transfer arm ultimately transfers a fully wound core back to the loading/unloading station where the wound core is unloaded from the transfer arm and then inverted.
