Description

Motor stator

Technical field

The utility model relates to motor component, especially relates to a kind of motor stator that can realize the insulation property improvement economically.

Background technology

Motor is widely used in every field as a kind of general dynamic power machine.No matter for example, the large-size machine that drives machine run is arranged, the small machine that drives the microminiature machine operation is also arranged, be large-size machine or miniature small machine, and its inside all is provided with the stator that coil can be installed.In order to improve its insulation property, in described stator interior insulating paper is set usually.Though it is easy to make that this structure has, the advantage of aspects such as cost is lower, but in the process of using it, still exist insulation property relatively poor, damage easily, the frequency height of changing, even be easy to deficiency such as burning, this has not only improved the cost of motor virtually, reduced profit margin, and high-frequency dismounting motor, will have a strong impact on the overall performance of motor, and shorten the life-span of motor.

Summary of the invention

The utility model mainly is that to solve the stator interior insulation property of existing in prior technology motor poor, and assembling is very convenient, clean and tidy, than the technical problem of easy firing etc.

It is higher that the utility model also solves existing in prior technology motor dismounting frequency simultaneously, the technical problem of the relatively poor grade of gas permeability.

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of motor stator, comprise stator punching, be located at the vertical groove in its outside, described stator punching is by placing the connector in the groove to be fixed into an annular stator body, the inboard of described stator punching is provided with several worker's type blades, its base portion is comparatively narrow, the end enlarges and end face is circular arc, each end face of each worker's type blade is arranged on the same circumference, and around the inboard of described each worker's type blade and connecting portion and stator inner loop to be provided with insulation nested.

As preferably, described insulation is nested to be divided into two up and down, is arranged on the two ends of stator body.

As preferably, the nested system of described insulation is by inserting in the interlobate slotting body of each worker's type, and the ring bodies of portion provided thereon and block body of being located in it constitute; Wherein, the internal diameter of the internal diameter of described block body and worker's type blade 2 is complementary.

As preferably, the height of the slotting body that described insulation is nested is the 20%-40% of stator body height.

As preferably, be to be connected between described ring bodies and block body by ogive, its inwall is provided with corresponding depression.

As preferably, the nested employing plastics of described insulation are made, and its average wall thickness is 0.1-0.8mm.

As preferably, the uniform connector that is arranged in the groove, its surface is equal to or less than the surface of the periphery body of stator body.

As preferably, the shape that described insulation is nested to be goed deep in the flute profile of stator body is consistent with the flute profile of stator body; And the interlobate spacing width of described worker's type is 2-5mm.

Therefore, it is good to the utlity model has motor stator built-in electrical insulation performance, and system is comparatively convenient with assembling, production cost is lower, and useful life is longer, and coil, conductor arrangement are more or less freely, the gas permeability and the cleaning of stator are better, whole security performance characteristics such as be greatly improved.

Accompanying drawing 1 is the structural representation of the utility model stator;

Accompanying drawing 2 is a kind of nested schematic diagrames that insulate of the present utility model.

Embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment:

Its body (as shown in Figure 1) in the form of a ring of stator body of the present utility model 1, it is that arranged outside at stator punching 3 has perpendicular groove 4, after stator punching 3 superimposed the compressing, fixedly form by connector 5 welding that are arranged in its outside groove, the surface that is arranged on the connector 5 in the groove 4 will be equal to or less than the surface of the periphery body of stator body 1.Be provided with several worker's type blades 2 in the inboard of stator punching 3, the base portion of worker's type blade 2 is comparatively narrow, and the end enlarges and end face is circular arc, and each end face of each worker's type blade 2 is arranged on the same circumference, and the spacing width of adjacent worker's type blade 2 is 2.5-5mm.Side periphery at worker's type blade 2 of stator punching 3 inboards is provided with insulation nested 7.Described insulation nested 7 is by the slotting body 71 that inserts in 2 in each worker's type blade, and the ring bodies 72 of portion provided thereon and the block body of being located in it 73 constitute.Wherein, described ring bodies 72 is to be connected by ogive 74 with 73 of block bodies, and its inwall is provided with corresponding depression; And the internal diameter of the internal diameter of described block body 73 and worker's type blade 2 is complementary (as shown in Figure 2).Usually, the two ends up and down of a stator body 1 in the described motor are provided with two insulation nested 7.Insulate and nested 7 can adopt injection molding to make, its ensemble average wall thickness is about 0.3mm.The shape of the slotting body of described insulation nested 7 is consistent with the shape of the groove 6 of stator body 1; And the spacing that described worker's type blade is 2 is about 3mm.

The utility model in use, the part that insulation nested 7 is similar to the shape of the groove 6 of stator body is inserted in the stator body accordingly, ring bodies 73 provided thereon and block body 74 place respectively on the outer ring body of worker's type blade 2 and stator, combine motor stator described in the utility model thus.Because nested 7 good insulation preformances of insulation have guaranteed to be located at the coil windings operate as normal in it, reduced common insulating paper technical pattern effectively and easily caused probability because of the breakdown burn-down of electric motor that causes.So not only reduced because of the lead group adopts the improper loss that brings of insulating material, and protected motor, prolonged the useful life of motor, reduced production cost, increased profit margin, helped being widely used.
