METHOD, SYSTEM, AND STRUCTURE OF STATOR WITH COMMON INSULATING AND VARNISHING RESIN

摘要

A stator having a common varnish and weld insulation includes a stator lamination core and a motor winding wound around the stator lamination core. The motor winding includes a plurality of magnet wires configured such that they are substantially parallel to each other. Each magnet wire has two distal ends configured such that each distal end is welded to one distal end of an adjacent magnet wire, thereby forming a plurality of welded tips. The stator further includes a resin coating the welded tips and the stator. The resin serves as both a primary insulation for the welded tips, and as a varnish for the stator. This dual function of the resin may eliminate the need for separate insulation for the welded tips and varnish for the stator, and allow the resin to be applied to the welded tips and to the stator at substantially the same time.

主权项

1. A method of insulating welded tips of a stator having a stator lamination core and a motor winding with the welded tips, and varnishing the stator, the method comprising:
applying a first layer of a resin to the stator via a first application process; and applying a second layer of the resin to the welded tips of the stator via a second application process, the second layer covering the first layer at the welded tips; wherein the resin serves both as a primary insulation for the welded tips and as a varnish for the stator.
