Abstract

A method of flaring stator windings includes supporting a first axial end of a stator core having first and second end turn portions on a first cuff having a first central opening. The first end turn portion extends through the first central opening. The method further includes positioning a second cuff having a second central opening upon a second axial end of the stator core with the second end turn portion extending through the second central opening, positioning a flaring guide having an angled surface upon the second cuff about the second end turn portion, aligning a flaring portion of a flare tool with the second end turn portion, urging the flaring portion between first and second stator winding layers forming the second end turn portion, and flaring the second stator winding layer radially outward of the stator core.

Claims (11)

1. A method of flaring stator windings, the method comprising:

supporting a first axial end of a stator core having first and second end turn portions on a first cuff having a first central opening, the first end turn portion extending through the first central opening;

positioning a second cuff having a second central opening upon a second axial end of the stator core with the second end turn portion extending through the second central opening;

positioning a flaring guide having an angled surface upon the second cuff about the second end turn portion;

aligning a flaring portion of a flare tool with the second end turn portion;

urging the flaring portion between first and second stator winding layers forming the second end turn portion; and

flaring the second stator winding layer radially outward of the stator core.

2. The method of claim 1 , further comprising: positioning a center plug radially inward of the first stator winding layer.

3. The method of claim 2 , further comprising: inserting another plurality of finger elements through the second cuff into the second end turn portion to further secure the stator core.

4. The method of claim 1 , further comprising: inserting a plurality of finger elements through the first cuff into the first end turn portion to secure the stator core.

5. The method of clam 1 , wherein positioning the flaring guide includes arranging multiple flaring guide segments about the second cuff.
