Abstract
The utility model discloses a novel motor stator, which comprises a stator iron core and a stator winding. The inner side wall of the stator core is provided with a plurality of grooves; the stator winding is wound on the stator core, and the parts of the stator core surrounding the inner side wall of the stator core are embedded in the grooves; and the outermost layer of the stator winding is provided with a layer of insulating material coated along the outermost layer of the stator winding. The utility model relates to a novel motor stator; the outermost layer of the stator winding is provided with the layer of insulating material coated along the outermost layer of the stator winding, so that carbon powder or dust particles falling to the outermost layer of the stator winding are isolated with the stator winding through the insulating material layer to prevent short circuit of the stator winding, and to avoid problems of influence on normal working and service life of the stator winding caused by short circuit due to falling of carbon powder or dust particles.
Description
Technical field
The utility model belongs to the motor technology field, specifically refers to a kind of motor stator.
Background technology
Motor is a kind of a kind of slewing that converts electric energy to mechanical energy, and wherein the stator of motor is the actionless part of motor, mainly for generation of rotating magnetic field.Known existing motor stator comprises stator core and stator winding, and wherein, the madial wall of stator core offers several grooves, and the stator winding winding is on stator core, and the position correspondence of winding on the iron core madial wall is embedded in each groove.
Yet, described existing motor is in High Rotation Speed work, its carbon brush carbon dust that easily comes off, this carbon dust easily descends slowly and lightly to stator winding, like this, treats that carbon dust on the stator winding runs up to when a certain amount of, stator winding punctures over the ground, cause the grounding of stator winding short circuit, stator can't be worked, even can reduce the useful life of stator; Extraneous dust granule easily descends slowly and lightly and causes stator winding to be worn to stator winding simultaneously, thereby causes stator winding also to be prone to short circuit phenomenon.
In view of this, the inventor conducts in-depth research motor stator structure, and this case produces thus.
The utility model content
The purpose of this utility model is to provide a kind of novel motor stator, and it can avoid existing stator winding to affect stator normal operation and the problem in useful life because carbon brush carbon dust or dust granule descend slowly and lightly short circuit phenomenon occurring.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of novel motor stator, comprise stator core and stator winding, the madial wall of this stator core offers several grooves, and this stator winding winding is on stator core, and the position correspondence of this stator winding winding at iron core madial wall place is embedded in each groove; Also be provided with the insulation material layer that applies along this stator winding outermost layer on the outermost layer of said stator winding.
Above-mentioned insulation material layer is the insulation glue-line.
After adopting such scheme, a kind of novel motor stator that the utility model relates to, it also is provided with the insulation material layer that applies around outermost layer along this stator on the outermost layer of stator winding, like this, descend slowly and lightly isolated by this insulation material layer and stator winding to the outermost carbon brush carbon dust of stator winding or dust granule, prevented that the phenomenon of short circuit from appearring in stator winding, avoided stator winding to affect stator normal operation and the problem in useful life because carbon brush carbon dust or dust granule descend slowly and lightly short circuit phenomenon occurring.

Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
A kind of novel motor stator of the utility model, as shown in Figure 1, 2, it comprises stator core 1 and stator winding 2, the madial wall of this stator core 1 offers several groove (not shown)s, these stator winding 2 windings are on stator core 1, and the position correspondence of these stator winding 2 windings at iron core 1 madial wall place is embedded in each groove (not shown), also be provided with the insulation material layer 3 that applies along these stator winding 2 outermost layers on the outermost layer of this stator winding 2, this insulation material layer 3 is the insulation glue-line.
A kind of novel motor stator that the utility model relates to, it also is provided with the insulating cement that applies around 2 outermost layers along this stator on the outermost layer of stator winding 2, like this, descend slowly and lightly isolated by this insulating cement and stator winding 2 to stator winding 2 outermost carbon brush carbon dusts or dust granule, prevented carbon dust energising or stator winding from being worn and torn by dust granule and the phenomenon of stator winding inter-turn short circuit fault occurred, thus avoided stator winding 2 because of carbon brush carbon dust or dust granule descend slowly and lightly upper appearance over the ground punch-through affect stator normal operation and the problem in useful life.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
