Abstract

The utility model relates to a stator insulation device for a motor. The stator insulation device comprises a stator body which is formed by a winding, a stator core and an insulation layer arranged between the winding and the stator core to insulate the winding from the stator core. The insulation layer is formed by a first insulation frame, a second insulation frame and groove insulation layers embedded in grooves, wherein the first insulation frame and the second insulation frame are respectively arranged on two axial sides of the stator core. The first insulation frame, the second insulation frame and the groove insulation layers are wrapped on the outer surface of the stator core. The shapes and the sizes of the first insulation frame and the second insulation frame are respectively matched with those of the end faces on two axial sides of the stator core. Insulation paper serves as the groove insulation layers, and the peripheries of the groove insulation layers are clamped in the first insulation frame and the second insulation frame. By means of the technical scheme, the insulation layer formed by the first insulation frame, the second insulation frame and the groove insulation layers jointly is of a split assembly structure and is simple in structure. Besides, the peripheries of the groove insulation layers are clamped in the first insulation frame and the second insulation frame, so that the insulation effect is relatively good.

Description

Stator insulated device used for motor

Technical field

The utility model relates to a kind of motor, relates to specifically a kind of stator insulated device used for motor.

Background technology

Dc brushless motor has been widely used in field of household appliances as the core drive that drive future.At present, general dc brushless motor be with stator coil in stator slot, with plastic structure coil is separated with iron core, to serve as insulation, namely directly dock the outer surface that is coated on stator core with first, second Insulating frame, the butt end face of this structure is prone to damage, therefore insulation system can be destroyed, and produces the phenomenon that punctures electric leakage during use, and the technological requirement of this kind structure is relatively high simultaneously, be not easy to reprocess, and can't realize producing in serial form.

The utility model content

The purpose of this utility model is to provide a kind of stator insulated device used for motor, and this seal is simple in structure, and insulation effect is good.

For achieving the above object, the utility model has adopted following technical scheme: comprise stator body, described stator body is by winding, stator core and be arranged on winding and stator core between the insulating barrier that both insulate is consisted of, described stator core comprises a plurality of tooth section that is circumferentially along stator core that radiated entends arranges, and the tooth ends that links to each other with each tooth section top, form groove between described two adjacent tooth sections, described insulating barrier is by being installed in respectively first of the axial both sides of stator core, the second Insulating frame, and the layer slot insulator that is embedded in each groove forms, described first, the second Insulating frame and layer slot insulator are coated on the outer surface of stator core, described first, the second Insulating frame respectively with the shape of the axial both sides of stator core end face, size matches, described layer slot insulator is insulating paper, and the card of layer slot insulator is located at first, in the second Insulating frame.

Described first, second Insulating frame is the injection mo(u)lding of PBT material monolithic.

As shown from the above technical solution, the utility model forms insulating barrier jointly by first, second Insulating frame and layer slot insulator, and insulating barrier is assembled structure, and is simple in structure, the card of layer slot insulator is located in first, second Insulating frame simultaneously, so insulation effect is relatively better.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

Such as Fig. 1-a kind of stator insulated device used for motor shown in Figure 4, comprise stator body 1, stator body 1 is by winding, stator core 2 and be arranged on winding and stator core 2 between the insulating barrier that both insulate is consisted of, stator core 2 comprises a plurality of tooth section 21 that is circumferentially along stator core 2 that radiated entends arranges, and the tooth ends 22 that links to each other with each tooth section 21 top, form groove 23 between two adjacent tooth sections 21, insulating barrier is by being installed in respectively first of stator core 2 axial both sides, the second

Insulating frame

31,32, and the layer slot insulator 33 that is embedded in each groove 23 forms, first, the second

Insulating frame

31,32 are coated on the outer surface of stator core 2 with layer slot insulator 33, in other words namely insulating barrier by first, the second Insulating frame and layer slot insulator form jointly, first, the second Insulating

frame

31,32 respectively with the shape of stator core 2 axial both sides end faces, size matches, layer slot insulator 33 is insulating paper, and the card of layer slot insulator 33 is located at first, the second Insulating frame 31, in 32.

As preferred version, first, second

Insulating frame

31,32 is the injection mo(u)lding of PBT material monolithic.

Concrete assembly method is as follows:

First insulating paper is inserted in the groove of stator core, again with axial two the faces insertion stator core of first, second Insulating frame from stator core, the the one the second Insulating frames block the periphery of insulating paper fixing, and namely insulating paper is between first, second Insulating frame and the stator core.

The beneficial effects of the utility model are: 1) first, second Insulating frame and layer slot insulator are split type package assembly, and technique is simple, have improved product percent of pass; 2) be easy to produce, improved yield in unit time; 3) be easy to reprocess, reduced product rejection rate; 4) split-type structural is conducive to realize the producing in serial form of product, and has reduced to a certain extent the material cost of product.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
