Background technology

At present, generally use first phase insulation paper the 02, second phase insulation paper 03 as shown in Figure 1 and interlayer exhausted Edge paper 01 realizes winding phase and phase, insulation between layers.In Double Layer Winding rule stator, the phase of adjacent two phase windings Two adjacent limits, become distribution to be up and down embedded in same slot for winding, and the winding that will be located in top is referred to as upper strata winding, will be located in The winding of lower section is referred to as lower floor's winding.Between upper strata winding and lower floor's winding that layer insulation paper 01 is positioned in slot for winding. After embedding complete upper strata winding and lower floor's winding, in one end of Double Layer Winding rule stator, with rod for drawing line separate adjacent upper strata around Group and lower floor's winding, and then insert the first phase insulation paper 02;At the other end of Double Layer Winding rule stator, separate with rod for drawing line Described adjacent upper strata winding and lower floor's winding, and then insert the second phase insulation paper 03.

But, during separating two phase windings with rod for drawing line, it is easily destroyed the magnet wire insulation layer of winding, also having can Solid wire misphase can be caused, in turn result in insulation breakdown.Further, since phase insulation paper is independent individuality, at transport bilayer During winding inserting stator, it is easy to cause phase insulation paper to occur crooked, in turn result in insulation breakdown.

Therefore, how to evade the use of rod for drawing line, the magnet wire insulation layer of protective winding, improves phase insulation paper simultaneously Steadiness, is those skilled in the art's critical problems urgently to be resolved hurrily.

Summary of the invention

It is an object of the invention to evade the use of rod for drawing line, the magnet wire insulation layer of protective winding, improve simultaneously alternate absolutely The steadiness of edge paper.

For reaching above-mentioned purpose, the present invention provides techniques below scheme:

A kind of insulating paper, including:

In the slot for winding being placed on Double Layer Winding rule stator, and the layer between upper strata winding and lower floor's winding Between insulating paper;

For being placed on one end of described Double Layer Winding rule stator, and it is positioned at described upper strata winding and described lower floor winding Between the first phase insulation paper;

For being placed on the other end of described Double Layer Winding rule stator, and be positioned at described upper strata winding and described lower floor around The second phase insulation paper between group;

Described layer insulation paper, described first phase insulation paper and described second phase insulation paper are structure as a whole.

Preferably, described first phase insulation paper and described second phase insulation paper are connected to described layer insulation paper Two ends, described first phase insulation paper, described second phase insulation paper and described layer insulation paper constitute single parantheses shape.

Preferably, described first phase insulation paper is connected with described layer insulation paper arc transition.

Preferably, described second phase insulation paper is connected with described layer insulation paper arc transition.

A kind of Double Layer Winding rule stator, including insulating paper, described insulating paper is any one insulating paper above-mentioned.

A kind of motor, including Double Layer Winding rule stator, described Double Layer Winding rule stator is above-mentioned Double Layer Winding rule Stator.

A kind of coil-inserting method, based on the insulating paper in above-mentioned, comprises the steps:

By the winding of the first phase while being embedded into the lower floor of described slot for winding, the winding of described first phase is described lower floor Winding;

The described layer insulation paper of insulating paper is embedded in described slot for winding, and regular described first phase insulation paper and Described second phase insulation paper;

By the winding of the second phase while being embedded into the upper strata of described slot for winding, the winding of described second phase is described upper strata Winding.

From technique scheme it can be seen that the insulating paper the present invention includes layer insulation paper, the first phase insulation paper And second phase insulation paper, and layer insulation paper, the first phase insulation paper and the second phase insulation paper be structure as a whole.? After slot for winding is embedded in lower floor's winding, the layer insulation paper of insulating paper is embedded in this slot for winding, and regular first phase Between insulating paper and the second phase insulation paper, be embedded in upper strata winding to slot for winding the most again, without at upper strata winding and After lower floor's winding embeds, utilize rod for drawing line to separate two phase windings, thus protect the magnet wire insulation layer of winding not by drawing The destruction of bar.Further, since the first phase insulation paper, the second phase insulation paper are structure as a whole with layer insulation paper, mutually Between involve effect, therefore the first phase insulation paper and the second phase insulation paper are not easily shifted, thus improve first alternate absolutely Edge paper and the steadiness of the second phase insulation paper.
