Abstract: A method for creating a composite article using fast heat treating thermoset resin materials for 3D printing articles, including articles of complex geometry. The method includes using vacuum impregnation and subsequent heat treating as post printing processes to further strengthen and enhance the functionality of the article.

Abstract: 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.

Abstract translation: 具有共同的清漆和焊接绝缘的定子包括定子叠片芯和缠绕在定子叠片芯上的电动机绕组。 电动机绕组包括多个电线，其配置成使得它们彼此基本平行。 每个电磁线具有两个远端，其构造成使得每个远端焊接到相邻电磁线的一个远端，从而形成多个焊接尖端。 定子还包括涂覆焊接尖端和定子的树脂。 树脂既用作焊接头的主要绝缘体，也用作定子的清漆。 树脂的这种双重功能可以消除对用于定子的焊接顶端和清漆的单独绝缘的需要，并且允许树脂基本上同时施加到焊接端头和定子。
