A kind of stator, comprise stator core and winding, described stator core is provided with dead slot, and described winding is arranged in described dead slot, be provided with the end face insulating trip be complementary with described leading-out terminal end face on the leading-out terminal end face of described stator core, described end face insulating trip and the laminating of described leading-out terminal end face.
In embodiment, the shape of described end face insulating trip is identical with the shape of the leading-out terminal end face of described stator core therein.
In embodiment, described end face insulating trip is fixedly connected with the leading-out terminal end face of described stator core therein.
In embodiment, described end face insulating trip is adhesively fixed by the leading-out terminal end face of insulating cement and described stator core therein.
In embodiment, the outward flange of described end face insulating trip is provided with outer therein, and described end face insulating trip is arranged on described stator core by described outer.
In embodiment, described end face insulating trip is provided with several fractures therein, and several described fractures are divided into two or more parts by described end face insulating trip.
In embodiment, at described dead slot madial wall, also be provided with insulating trip therein, the insulating trip of described end face insulating trip and described dead slot madial wall is one-body molded.
The utility model also provides a kind of motor, comprises stator and rotor, and described stator is stator as above.
The stator that the utility model provides and motor, because the insulating trip of the leading-out terminal end face of stator core has completely cut off the winding vertical line, too small and the short circuit current that causes of the leading-out terminal end face distance of having avoided winding vertical line and iron core and puncturing, the stator electrical safety performance is guaranteed to some extent, and then it is withstand voltage bad to have eliminated the motor produced by the winding vertical line, increased life-span and the security performance of motor.
The accompanying drawing explanation
The structural representation of the embodiment that Fig. 1 is stator of the present utility model;
The structural representation of another embodiment that Fig. 2 is stator of the present utility model;
The structural representation of another embodiment that Fig. 3 is stator of the present utility model;
The structural representation of the embodiment that Fig. 4 is motor of the present utility model.
Embodiment
Referring to Fig. 1 to Fig. 3, the utility model provides a kind of stator, comprise stator core 110 and winding 120, the madial wall of stator core 110 has equally distributed dead slot 112, winding 120 is arranged in dead slot 112, the leading-out terminal end face 114 of stator core 110 tightens to be sticked and is equipped with the end face insulating trip 140 that the leading-out terminal end face 114 with stator core 110 is complementary, end face insulating trip 140 and 114 laminatings of leading-out terminal end face.
In the stator provided at above-described embodiment, end face insulating trip 140 will be complementary with the leading-out terminal end face 114 of stator core, according to the number of the size of different motor stator core end faces 114 and dead slot 112, designs size and the hole of insulating trip 140.When stator is assembled, we are arranged on insulating trip 140 on the leading-out terminal end face 114 of stator core, then winding 120 is embedded in dead slot 112.Because the leading-out terminal end face 114 of stator core is provided with insulating trip, completely cut off the enamelled wire vertical line, the stator electrical safety performance is guaranteed to some extent.
It should be noted that, the material of insulating trip has diversity, can be plastics, can be also resin, or other material that can insulate.
Preferably, the shape of end face insulating trip 140 can be identical with leading-out terminal end face 114 shapes of stator core 110.The insulating trip of this kind of design has been saved insulating material, and convenient when embedding winding.
Further, end face insulating trip 140 can be fixedly connected with the leading-out terminal end face 114 of stator core 110.End face insulating trip 140 is fixedly connected on the leading-out terminal end face 114 of stator core 110, can makes total more stable.
Preferably, end face insulating trip 140 can be adhesively fixed by the leading-out terminal end face 114 of insulating cement and stator core 110.This connected mode is convenient easily to be implemented, and cost is lower.
As preferably, the outward flange of end face insulating trip 140 is provided with outer 144, and as shown in Figure 3, end face insulating trip 140 can be arranged on stator core 110 by outer 144.When carrying out the assembling of stator, the technical staff can directly be buckled in the outer of end face insulating trip 140 144 on iron core 110, and the end face insulating trip 140 of this structure and the leading-out terminal end face 114 of stator core 110 are in conjunction with firm and easy and simple to handle.
Further, several fractures 142 can be set on end face insulating trip 140, several fractures 142 are divided into two or more parts by end face insulating trip 140, can respectively two or more parts be arranged on stator core 110.The number of fracture 142 is not limited to, can be one, two or more, the embodiment that Fig. 2 is two fractures 142.When carrying out the making of end face insulating trip 140, we can first be made into whole shape, and then it is cut to fracture 142; Also can utilize particular mold to adopt the means such as injection mo(u)lding directly to be made into the shape that has fracture 142.Exist the end face insulating trip 140 of fracture 142 more flexible when mounted, we can first be arranged on end face insulating trip 140 on the leading-out terminal end face 114 of stator core 110, then winding 120 is installed in dead slot 112; Also can first winding 120 be installed in dead slot 112, then end face insulating trip 140 be fastened on the leading-out terminal end face 114 of stator core 110.In addition, there is the insulating trip 140 of fracture 142 to be convenient to existing stator is assembled again.
Further, at dead slot 112 madial walls, also be provided with insulating trip 130, end face insulating trip 140 is one-body molded with the insulating trip 130 of dead slot 112 madial walls.When stator is assembled, first section insulating trip 140 is arranged on stator core end face 114, then carries out the installation of corresponding winding 120.Integrated structure has been avoided the installation respectively of end face insulating trip 140 with the dead slot 112 madial wall insulating trips 130 of stator core 110, has saved man-hour, simultaneously, more can effectively prevent contacting of stator core 110 and winding 120, and security performance is stronger.
Referring to Fig. 4, the utility model also provides a kind of motor, comprises front end housing 400, rotor 300 and rear end cap 200, also comprises the stator 100 that above arbitrary embodiment provides.Owing to having adopted the stator 100 that is provided with the end face insulating trip, that has avoided producing because of the winding vertical line is withstand voltage bad, has increased the security performance of motor.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
