Abstract
The utility model relates to an insulated stator. The corresponding groove is punched on each T-shaped silicon steel sheet plane, so that the convex block with concave-up and convex-down formed from the punching on the other T-shaped silicon steel sheet bottom plane layer of the utility model in crlt circulation can be precisely inserted into the groove on the lower T-shaped silicon steel sheet plane layer. Two insulated slots are also opened on the top of the T-shaped silicon steel sheet. After layers of stacking and pressing together of the T-shaped silicon steel sheet, a stator is formed. The coil of the stator is wound on both sides of the T-shaped silicon steel sheet. The stator disposed in the die is in the formation of an insulated stator after the insulation resin filling and die moulding. An insulation material layer is coated on the surface and outer layer of the insulated stator so that the short circuit will not occur on the coil, while the insulated slots opened on both ends of the T-shaped silicon steel sheet plays a role of the insulation each other between the coils. At the same time the temperature rise caused by the vortex is reduced, so that the service life of the motor stator can be enhanced.
Description
Technical field: the utility model relates to the motor that uses in a kind of air-conditioning, the washing machine, particularly relates to a kind of insulation stator in the motor.
Technical background: widely used in daily life air-conditioning, motor for washer, its core component is a motor stator, and the processing of the tradition of motor stator, general all is to adopt silicon steel sheet after striking out certain shape, according to certain position and angle, overlapped then, riveted joint forms.The motor stator of producing like this, the processing technology more complicated needs very skilled operator on the one hand.Because stator has adopted the single face punching out, can cause the very big waste of materials processing on the other hand, be unfavorable for reducing the cost of product and improve work efficiency.And the motor stator of producing is on-insulated, causes short circuit easily, and the electric machine temperature rise height often has the generation of motor dieseling.
Summary of the invention: the purpose of this utility model will provide a kind of insulation stator exactly, to overcome the existing defective of traditional processing, improves the raw-material utilance and the class of insulation, stops the generation of the easy dieseling of motor.The purpose of this utility model is achieved in that a kind of insulation stator, is made up of the rectangular silicon steel sheet of T type, coil, it is characterized in that: described stator adopts by overlapping the forming of spiraling of the long strip type silicon steel sheet after the punching out of certain specification size; Described long strip type silicon steel sheet is connected by several T type silicon steel sheets, all punching out has corresponding groove on each T type silicon steel sheet plane, the last recessed protruding projection through punching out forms on its another layer T type silicon steel sheet baseplane that spirals up is just in time inserted in the groove on the T of the lower floor type silicon steel sheet plane, and T type silicon steel sheet also has two insulation tanks on its top; Described silicon steel sheet overlaps together the formation stator through layer by layer, and its coil winding is in the both sides of T type silicon steel sheet; Stator is placed in the pressing mold, through insulation resin fill, pressing mold, forms insulation stator; Around the stator that described insulation stator is formed at its T type silicon steel sheet by specification requirement be full of, compacting one deck insulating material, and in the insulation tank that open on the top of T type silicon steel sheet, also be full of insulating material.The invention solves the defective of the easy down in working order intensification of stator, short circuit.The cost of the insulation stator of production is reduced greatly, improved the automatization level of producing.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an end view of the present utility model.
Fig. 3 is the rectangular structural representation that is made into stator of T type silicon steel sheet of the present utility model.
1. insulation stator, 2. insulating material, 3. insulation tank, 4. coil, 5.T type silicon steel sheet, 6. stator, 7. groove.
Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing.
In the drawings, a kind of insulation stator of the utility model is made up of the rectangular silicon steel sheet of T type, coil, it is characterized in that: described stator 6 adopts by overlapping the forming of spiraling of the long strip type silicon steel sheet after the punching out of certain specification size; Described long strip type silicon steel sheet is connected by several T type silicon steel sheets 5, all punching out has corresponding groove 7 on each T type silicon steel sheet 5 plane, the last recessed protruding projection through punching out forms on its another layer T type silicon steel sheet 5 baseplanes that spiral up is just in time inserted in the groove 7 on the T of lower floor type silicon steel sheet 5 planes, and T type silicon steel sheet 5 also has two insulation tanks 3 on its top; Described silicon steel sheet overlaps together through layer by layer and forms stator 6, and its coil 4 is wound on the both sides of T type silicon steel sheet 5; Stator 6 is placed in the pressing mold, through insulation resin fill, pressing mold, forms insulation stator 1; Around the stator 6 that described insulation stator 1 is formed at its T type silicon steel sheet 5 by specification requirement be full of, compacting one deck insulating material 2, and in the insulation tank 3 that open on the top of T type silicon steel sheet 5, also be full of insulating material 2.During concrete enforcement, silicon steel sheet is processed into T type silicon steel sheet on punch press, is provided with the aperture that is connected between the described T type silicon steel sheet, aperture is an open structure.Design so rectangular silicon steel sheet of T type and can bend to the stator of different size diameter according to the difference of production specification, every layer of T type silicon steel sheet is by in the concavo-convex hole of its surperficial punching press, overlapped, be pressed together, form stator.Behind coiling on the described stator; the coiling stator is put into carries out injection moulding in the pressing mold; its surface and outer parcel one deck insulating material; be used for protecting the coil of institute's coiling can not cause short circuit; and the insulation tank of opening at the two ends of T type silicon steel sheet; can play the effect of mutually insulated between the coil on the one hand, can reduce eddy current by set insulation tank on the other hand and give the temperature rise that stator brought, thereby improve the useful life of motor stator.
