Abstract:
1. Apparatus for winding wire coils onto dynamo-electric machine components comprising: a needle assembly configured to wind wire onto the machine component; an outer shaft operationally engaged with the needle assembly, said outer shaft configured to simultaneously impart to the needle assembly rotational motion about a central axis and translational motion along the central axis; an inner shaft operationally engaged with the needle assembly and the outer shaft configured to mirror the rotational motion of the outer shaft about the central axis, said inner shaft further configured to rotate about the central axis in relation to the outer shaft to provide stratification motion to the needle assembly substantially perpendicular to the central axis; a first sleeve coaxially disposed about a first portion of the outer shaft configured to rotate about the central axis to impart translational motion to the outer shaft; and a first motor configured to rotate said first sleeve about the central axis; wherein the first portion of the outer shaft and the first sleeve possess corresponding helical channels for translating the rotational motion of the first sleeve into translational motion of the outer shaft.
