In the novel stator, the inner side edge of the protective sleeve is provided with a wavy winding groove for embedding a copper wire, and the winding groove is located at the connecting part of the embedding part and the flanging. The outer end border of lag is equipped with the wire winding groove that supplies the copper line embedding, has better location effect to the copper line, avoids the copper line to produce the skew when the wire winding.

In the novel stator, the height of the embedded part is 3-6 times of the thickness of the stator sheet. By adopting the arrangement, the anti-skid sleeve has the advantage of lower manufacturing cost.

In the novel stator, the protective sleeve is made of plastic material. The lag adopts plastics to make, has the better and better advantage of insulating effect of protecting effect.

In the novel stator, the middle part of the protective sleeve is provided with a metal sheet for reinforcement, and the metal sheet and the protective sleeve are of an integral structure.

In the novel stator, the middle part of the stator body is inserted with a plurality of cooling pipes which are connected in series in sequence. Through foretell cooling tube, cool off stator body, improved the life of this novel stator.

Compared with the prior art, this novel stator has following advantage:

1. during winding, the copper wire is wound on the outer side of the protective sleeve, so that the copper wire and the stator body are well protected, a good insulation effect is achieved, and the service life is prolonged;

2. the edge of the outer end of the protective sleeve is provided with a winding groove for embedding a copper wire, so that a good positioning effect is achieved on the copper wire, and the copper wire is prevented from deviating during winding;

3. the height of the embedded part is 3-6 times of the thickness of the stator sheet, so that the anti-skid sleeve has the advantages of low manufacturing cost and good protection effect;

4. the lag adopts plastics to make, has the better and better advantage of insulating effect of protecting effect.
