Abstract
A wire guide for winding wire onto the ferromagnetic core of a dynamo-electric machine part to form wire coils in the slots of the core. The wire guide has guide surfaces that allow wire to be wound deeply into the slots of the core. The wire guide also has a pair of coil retention notches. The notches have back walls that prevent wire from climbing along the sides of the slots toward the slot openings during the process of coil winding.
Claims14
A wire winding guide for use in a wire winding machine having a rotating flyer that dispenses wire for winding into slots of a ferromagnetic core of a dynamo-electric machine part to form wire coils, the slots having sides that extend radially outward from a central longitudinal axis of the core, radially outermost portions away from the central longitudinal axis of the core, bottoms that extend longitudinally along said core, and slot openings defined by the radially outermost portions of the sides, the wire winding guide comprising:
- a pair of smooth and continuous outer guide surfaces, wherein each surface has a leading guide edge and is movable with respect to the core during winding of the coils;
- and
- a pair of coil retention notches, each notch having a back wall that prevents the wire from climbing the sides of the slots as the wire is wound into the slots by the flyer, wherein the back walls of the coil retention notches are repositionable with respect to the core during winding of the coils.
A method for using a wire winding guide to guide wire from a rotating flyer dispensing the wire into slots of a ferromagnetic core of a dynamo-electric machine part to form wire coils, the slots having sides that extend radially outward from a central longitudinal axis of the core, radially outermost portions away from the central longitudinal axis of the core, bottoms that extend longitudinally along said core, and slot openings defined by the radially outermost portions of said sides, the method comprising:
- guiding the wire along a pair of smooth and continuous outer guide surfaces on the winding guide, over leading guide edges of the surfaces, and deeply into the slots
- preventing the wire from climbing the sides of the slots with back walls of a pair of coil retention notches as the wire is wound into the slots by the flyer;
- and
- repositioning the back walls of the coil retention notches to different distances with respect to the core axis during winding of the coils.
