  • Patent number: 6848479
    Abstract: The present invention concerns improved methods and apparatus for forming undulated wire coils that are placed into the cores of dynamo electric machine components. In particular, the invention concerns improved methods and apparatus for controlling the direction of deposit (along the axis about which the coil is wound) for the turns of a wire coil and for positioning the leads of the coil. This is accomplished by forming a series of wire coils using a programmable apparatus that controls a sequence of directions (along the coil axis) in which the wire turns are deposited, as well as positions of the final leads. The same methods and apparatus may also be used to form continuously wound wire portions.

  • Patent number: 6718624
    Abstract: The invention relates to a method for cable preparation, comprising two coupled devices (1, 2) for cable preparation, for example a cable preparation machine (1a) and a coiling device (2a). It furthermore relates to a device for carrying out the method and a system comprising a cable feed device, a cable insulation stripping device and a coiling device, all of which employ a novel program control (3, 4) in order to optimize the preparation procedure, for example the coiling, with regard to the feed values of the cable preparation machine (1a), so that a lower cable loading results without it being necessary to measure cable tension values.

  • Publication number: 20020148526
    Abstract: Apparatus and methods for reducing the likelihood of damage to wire leads of undulated coils for dynamo-electric machine stators are provided. The invention provides a rotating winding head equipped with a coil former that has a wire gripper and an initial wire lead slot. The gripper retains the initial wire lead. The slot permits the initial wire lead to be fed to the gripper from a stationary wire source. The gripper maintains the initial wire lead in a predetermined plane of the coil and can secure the initial wire lead in the plane in which the final lead wire will eventually be disposed. The gripper also rotates the initial wire lead into radial alignment with a lobe of the undulated coil. Once installed in a stator, the initial and final wire leads can both be disposed along the outer radius of the coil and are thus protected from interference with a rotor that is destined to rotate within the stator.

  • Patent number: 6343764
    Abstract: A method of preventing loosening of a wire wound around a reel for fastening reinforcing bars. The method comprises pressurizing an outer circumferential surface of the wire inwardly in the radius directions of the reel so that elastic forces in the directions which the outer diameter of the wire is increased are deprived therefrom, and the condition of wound wire is maintained after the pressure is released.

  • Patent number: 6255756
    Abstract: A stator coil winding arrangement comprises an inner layer and an outer layer, which define the two layers of the coil. A first turn of the inner layer is positioned directly over the outer layer. All subsequent turns of the inner layer return to the inner layer to be positioned over the inner layer. With this winding arrangement, total losses in the stator coil are reduced by approximately a factor of two.

  • Patent number: 6223784
    Abstract: A method and device for producing wave windings for an electrical machine, especially for a three-phase generator, is described in which each phase has a wave winding (12) divided into two winding halves (12a,12b), which are first deformed into a wavy star shape, are offset from one another by one pole pitch, and are finally inserted jointly into the grooves of a stator lamination packet. A simple and reliable method for production of this wave winding includes first winding a first winding half (12a) in a first winding direction in a circular or polygonal shape, and then switching over the continuous winding wire (15) in a winding loop (21) into the opposite winding direction, then winding the second winding half (12b) in the opposite winding direction and deforming both winding halves simultaneously into a star shape, offsetting both winding halves (12a, 12b) with respect to each other by one pole pitch (p) so that the winding loop (21) between the winding halves transitions into the star shape.
