Insulation paper, double-layer winding wire embedded stator, motor and wire embedding method

Abstract

The present invention discloses insulation paper. The insulation paper comprises interlayer insulation paper, first interphase insulation paper and second interphase insulation paper, wherein the interlayer insulation paper, the first interphase insulation paper and the second interphase insulation paper are of an integral structure. After a low-layer winding is embedded in a winding groove, the interlayer insulation paper of the insulation paper is embedded in the winding groove, and the first interphase insulation paper and the second interphase insulation paper are arranged properly, and then, an upper-layer winding is embedded in the winding groove, and therefore, the insulation layers of the enameled wires of the windings will not be damaged by a scribing rod; and the interlayer insulation paper, the first interphase insulation paper and the second interphase insulation paper are of the integral structure, the interlayer insulation paper, the first interphase insulation paper and the second interphase insulation paper can drag each other, and therefore, the first interphase insulation paper and the second interphase insulation paper have little possibility of moving, and thus, the stability of the first interphase insulation paper and the second interphase insulation paper can be improved. The invention also discloses a double-layer winding wire embedded stator, a motor and a wire embedding method.

Description

technical field [0001] The invention relates to the field of motor insulation, and more specifically relates to an insulating paper, a double-layer winding embedded wire stator, a motor and a wire embedded method. Background technique [0002] Currently, the usual figure 1 The first interphase insulating paper 02, the second interphase insulating paper 03, and the interlayer insulating paper 01 are shown to realize the insulation between winding phases and phases, and between layers. In the double-layer winding embedded wire stator, the two adjacent sides of the adjacent two-phase windings are distributed up and down and embedded in the same winding slot. The upper winding is called the upper winding, and the lower winding is called the upper winding. lower winding. Place the interlayer insulating paper 01 between the upper winding and the lower winding in the winding slot. After the upper layer winding and the lower layer winding are embedded, at one end of the double-la...

Problems solved by technology

[0003] However, in the process of separating the two-phase windings with a scribing rod, it is easy to damage the enameled wire insulation layer of the windings, and it may also cause phase misalignment of a single wire, resulting in insulation breakdown

In addition, since the interphase insulating paper is an independent entity, it is easy to cause the interphase insulating paper to be skewed during the transportation of the double-layer winding embedded wire stator, thereby causing insulation breakdown
