Abstract
An enameled wire for a machine winding comprises a magnetic core body and an insulation layer coated outside the magnetic core body, wherein the magnetic core body comprises a steel core and a copper layer coated outside the steel core, the insulation layer is made of polyester or polyurethane or polyimide, the copper layer is coated outside the steel core through a squeezing and pressing manner, and the steel core is made of Q1 NO. 95 steel. The enameled wire of the machine winding has not only performances of high strength and high thermal resistance of steel but also performances of high electric conduction and good anticorrosion of copper, has good magnetoconductivity and good high frequency characteristic, and has the advantages of fast magnetoconductivity and stable start of a motor when being applied on the machine winding; as the enameled wire adopts double metal material, the cost of the enameled wire is lower than that of the traditional enameled wire made of pure copper, so that the purpose of lowering cost is achieved, and copper resource is saved.
Description
Technical field
The utility model belongs to the electrical material field, particularly a kind of enamelled wire that is used for motor windings.
Background technology
Therefore enamelled wire is a principal item of motor windings lead, is made up of copper busbar and insulating barrier usually, because fine copper density is big, price is high, has poor heat resistance, weight is big, cost is high shortcoming with the motor windings of fine copper enamelled wire making.In addition, adopt traditional fine copper enamelled wire to have non-magnetic characteristics, when using, can reduce the main flux of motor, reduce electric motor starting speed as motor windings.
Summary of the invention
The purpose of this utility model is to seek the substitute of traditional fine copper enamelled wire, overcomes its deficiency, proposes a kind of motor windings enamelled wire with permeance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of motor windings enamelled wire, it comprises magnetic conductive core and is coated on the outer insulating barrier of described magnetic conductive core, the copper layer that described magnetic conductive core comprises steel core and is coated on the described steel core outside.
The utility model further technical scheme is: the constituent material of described insulating barrier is polyester or polyurethane or polyimides.
Further, described copper layer is coated on the described steel core outside by extrusion.
Further, the constituent material of described steel core is the Q195 steel.
Because the technique scheme utilization, the utility model compared with prior art has following advantage and effect:
1, motor windings of the present utility model not only has the high strength and the high-fire resistance energy of steel with enamelled wire, and has the high conductivity of copper and good corrosion resistance;
2, the utlity model has good magnetic conductivity and good high frequency characteristics, be applied in have on the motor windings that magnetic conduction is fast, electric motor starting advantage stably;
3, adopt enamelled wire coiling motor windings of the present utility model can improve the main flux of motor, reduce leakage flux, thereby improve electric efficiency; Under the under-supply situation of capacitor, can adopt the magnetic circuit system of original capacitor motor, make the starting winding and do not need to use capacitor with enamelled wire of the present utility model, just can guarantee to obtain the original power of capacitor motor, only need change the number of turn of starting winding during application to get final product;
4, the utlity model has braze ability, ease of connection, connection reliable, around good, the safe and reliable advantage of property;
5, the utility model is owing to adopt bimetallic material, and its price is cheaper than traditional fine copper enamelled wire, reaches the purpose that reduces cost, and has saved the copper resource.
Description of drawings
Wherein: 1, steel core; 2, copper layer; 3, insulating barrier; 4, magnetic conductive core.
Embodiment
Shown in accompanying drawing 1, a kind of motor windings enamelled wire, it comprises magnetic conductive core 4 and the insulating barrier 3 that is coated on outside the described magnetic conductive core 4, described insulating barrier 3 forms by scribble polyester or polyurethane or polyimides at copper layer 2 outer surface.The copper layer 2 that described magnetic conductive core 4 comprises steel core 1 and is coated on described steel core 1 outside.Described copper layer 2 is coated on described steel core 1 outside by extrusion.The good Q195 steel of steel core 1 preferred magnetic conductivity.Therefore steel has permeance, can play magnetic conduction, improves the tensile strength of enamelled wire and improve the effect of the mechanical performance of enamelled wire; Copper has good conductivity and corrosion resistance, therefore can play the effect that improves conductivity and protection internal layer steel core.
The utility model can be made the enamelled wire of various different models according to different needs, and specification commonly used is 0.05～0.60mm.
The density of enamelled wire of the present utility model be same size the fine copper enamelled wire 88%, this can effectively reduce the weight of electromagnetism winding, the utility model can also be applied to voice coil, magnetic conduction coil and frequency applications field in addition, can obviously improve the product electric property.In addition, the utility model adopts the copper covered steel magnetic conductive core can also increase the tensile strength of enamelled wire and significantly improves the mechanical performance of enamelled wire.Compare with the fine copper enamelled wire, motor windings of the present utility model can reduce by 20%～40% with the production cost of enamelled wire.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection range of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection range of the present utility model.
