Abstract
The invention relates to a stator insulation device for a motor. The stator insulation device comprises a stator body, wherein the stator body comprises a winding, a stator iron core and an insulation layer arranged between the winding and the stator iron core to ensure that the winding is insulated from the stator iron core, the insulation layer comprises a first insulation frame and a second insulation frame which are respectively arranged on two axial sides of the stator iron core, and groove insulation layers embedded in grooves, the first and the second insulation frames and the groove insulation layers are covered on the outer surface of the stator iron core, the first insulation frame and the second insulation frame are respectively coincident with end faces of two axial sides of the stator iron core in shapes and sizes, the groove insulation layers are made of insulation paper, and peripheries of the groove insulation layers are clamped in the first and the second insulation frames. Known from the technical scheme, the first and the second insulation frames and the groove insulation layers form an insulation layer together, the insulation layer is of a split assembly structure, thus the stator insulation device has a simple structure; and the peripheries of the groove insulation layers are clamped in the first and the second insulation frames, thus the stator insulation layer is relatively better in insulation effect.
Description
Technical field
The present invention relates to a kind of motor, relate to a kind of stator for motors seal specifically.
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, just 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 higher relatively simultaneously; Be not easy to reprocess, and can't realize producing in serial form.
Summary of the invention
The object of the present invention is to provide a kind of stator for motors seal, this seal is simple in structure, and insulation effect is good.
For realizing above-mentioned purpose; The present invention has adopted following technical scheme: comprise stator body; Described stator body by winding, stator core and be arranged on winding and stator core between both are insulated insulating barrier constitute; Described stator core comprises a plurality of tooth portion that is circumferentially along stator core that radial extension arranges, and the tooth ends that links to each other with each tooth portion top, forms groove between described two adjacent tooth portions; Described insulating barrier is by first, second Insulating frame that is installed in the axial both sides of stator core respectively; And the layer slot insulator that is embedded in each groove forms, and described first, second Insulating frame and layer slot insulator are coated on the outer surface of stator core, and described first, second Insulating frame matches with shape, the size of the axial both sides of stator core end face respectively; Described layer slot insulator is an insulating paper, and the card of layer slot insulator is located in first, second Insulating frame.
Described first, second Insulating frame is the injection mo(u)lding of PBT material monolithic.
Can know by technique scheme; The present invention 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 better relatively.

Embodiment
Below in conjunction with accompanying drawing the present invention is further specified:
Like Fig. 1-a kind of stator for motors seal shown in Figure 4; Comprise stator body 1; Stator body 1 by winding, stator core 2 and be arranged on winding and stator core 2 between both are insulated insulating barrier constitute; Stator core 2 comprises a plurality of tooth portion 21 that is circumferentially along stator core 2 that radial extension arranges; And the tooth ends 22 that links to each other with each tooth portion 21 top, forming groove 23 between two adjacent tooth portions 21, insulating barrier is by first, second Insulating frame 31,32 that is installed in stator core 2 axial both sides respectively; And the layer slot insulator 33 that is embedded in each groove 23 is formed; First, second Insulating frame 31,32 and layer slot insulator 33 are coated on the outer surface of stator core 2, and in other words just insulating barrier is made up of first, second Insulating frame and layer slot insulator jointly, and first, second Insulating frame 31,32 matches with shape, the size of stator core 2 axial both sides end faces respectively; Layer slot insulator 33 is an insulating paper, and the card of layer slot insulator 33 is located in first, second Insulating frame 31,32.
As preferred version, first, second Insulating frame 31,32 is the injection mo(u)lding of PBT material monolithic.
Concrete assembly method is following:
Earlier 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 one the second Insulating frames block the periphery of insulating paper fixing, and just insulating paper is between first, second Insulating frame and the stator core.
Beneficial effect of the present invention is: 1) first, second Insulating frame and layer slot insulator are split type package assembly, and technology 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 helps realizing Products in Series production, and has reduced the material cost of product to a certain extent.
Above-described embodiment describes preferred implementation of the present invention; Be not that scope of the present invention is limited; Design under the prerequisite of spirit not breaking away from the present invention; Various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection range of claims of the present invention.
