Abstract

Methods and apparatus are provided for automatically adapting a stator winding station to wind stator cores of different lengths, without changing the lengths of the winding needles installed in the winding machine, and with minimum operator intervention. The method includes the step of translating the stator core, depending upon its length, to maintain the midpoint of the stator core at a fixed distance from a suitable reference frame, for example, the winding machine. Apparatus comprising first and second precision movement locators are described, wherein the first locator carries a stator housing, and the second locator carries lead termination equipment. The apparatus is adjusted automatically to position the stator core in a predetermined relation to the stator winding station, based on the length of the stator core to be wound.

Dependent claims

A method of winding coils onto each one of at least first and second stator cores, said first stator core having a longitudinal axis, a first length, a midpoint and an endface, said second stator core having a longitudinal axis, a second length, a midpoint and an endface, said second length being shorter than said first length, said coils being would using a winder having a longitudinal axis and a stroke which is adjustable between a longer stroke and a shorter stroke, wherein said longer stroke and said shorter stroke have midpoints that coincide with each other, said method comprising the steps of:

a. aligning said first stator core so that its longitudinal axis is parallel with said longitudinal axis of said winder;
b. abutting said endface of said first stator core against a reference plane to determine the location of said midpoint of said first stator core;
c. adjusting said winder to provide said longer stroke;
d. translating said first stator core relative to said winder so that said midpoint of said first stator core coincides with said midpoint of said longer stroke;
e. operating said winder to dispose coils onto said first stator core;
f. removing said first stator core from said winder;
g. aligning said second stator core so that its longitudinal axis is parallel with said longitudinal axis of said winder;
h. abutting said endface of said second stator core against said reference plane to determine the location of said midpoint of said second stator core;
i. adjusting said winding machine to provide said shorter stroke;
j. translating said second stator core relative to said winder so that said midpoint of said second stator core coincides with said midpoint of said shorter stroke;
and
k. operating said winder to dispose coils onto said second stator core.

e. removing said first stator core from said winder;
f. aligning said second stator core so that its longitudinal axis coincides with said longitudinal axis of said winder;
g. adjusting said winder to provide said shorter stroke;
h. translating said second stator core a second distance relative to said winder so that said midpoint of said second stator core coincides with said midpoint of said shorter stroke, said second distance being difference from said first distance;
and
