Abstract
A phase separator for an electric machine includes a first insulator and a second insulator. The first and second insulators each include a leg portion and an endturn portion connected to the leg portion. The endturn portion is asymmetric with respect to an axis defined by the leg portion such that the second insulator can be inverted and disposed in an overlapping arrangement for electrically insulating endturn portions of adjacent phase windings.
Claims16
A phase separator for an electric machine, comprising:
- separate first and second insulators, each insulator including:
- a leg portion;
- and
- an endturn portion connected to the leg portion, wherein the endturn portion is asymmetric with respect to an insulator axis extending along the leg portion relative to a rotation axis of the electrical machine for electrically insulating adjacent phase winding endturn portions,
- wherein the first insulator has an overlaying insulator portion,
- wherein the second insulator has an underlying insulator portion, and
- wherein the underling insulator portion is between the insulator leg portions and is in sliding engagement with the overlaying insulator portion to accommodate movement between the first insulator and the second insulator.
