Abstract
The invention discloses a special composite enamelled wire used for a vehicle engine and a motor. The special composite enamelled wire comprises a copper flat wire (1), the copper flat wire (1) is provided with fillets, and fillet radius is half of the narrow edge of the copper flat wire (1). The external of the copper flat wire (1) is provided with a composite paint layer. The special composite enamelled wire is advantaged by small space occupation. When the special composite enamelled wire is used, the resistance of a motor coil is reduced, and coil capacitance is improved, so that requirements of large-capacitance high-load usage occasion of the motor can be preferably satisfied.
Description
Technical field
the present invention relates to a kind of enamelled wire, particularly a kind of extraordinary composite enameled wire for automobile engine motor.
Background technology
automobile industry is the important pillar industry of national economy, is also the significant industry embodying national competitiveness.In recent years, Chinese Auto Industry continues to maintain fast-developing situation, and in national economy, status improves constantly, and automobile volume of production and marketing leaps to the first in the world.China's auto outputs in 2010 and sales volume are all more than 1,800 ten thousand, and speedup is more than 30% on year-on-year basis, occupies first place in the world; Within 2011, break through 2,000 ten thousand; Expect the year two thousand twenty, China's automobile guarantee-quantity will more than 200,000,000, and according to current automobile crude oil economy horizontal estimated, automobile-used crude oil consumption amount is by breakthrough 400,000,000 tons.But be a kind of unsustainable development according to the development of production conventional fuel oil automobile steering, therefore new-energy automobile arises at the historic moment.A large amount of copper enamelled wires is employed in the engine of new-energy automobile (electric automobile).But space occupancy rate is high in use for traditional round enamelled wire, and copper factor cannot improve, easily makes motor coil produce the problem that resistance is large, electric capacity is little, thus the requirement of bulky capacitor high capacity use occasion cannot be met.
Summary of the invention
the object of the invention is to, a kind of extraordinary composite enameled wire for automobile engine motor is provided.The present invention has the advantage occupied little space, and can reduce the resistance of motor coil, and improve coil capacity during use, thus can meet the requirement of the bulky capacitor high capacity use occasion of motor better.
technical scheme of the present invention: a kind of extraordinary composite enameled wire for automobile engine motor, it is characterized in that: comprise copper lenticular wire, copper lenticular wire is provided with fillet, and radius of corner is 0.5 times of the narrow limit of copper lenticular wire; Described copper lenticular wire is outside equipped with compound enamelled coating.
above-mentioned in the extraordinary composite enameled wire of automobile engine motor, the long limit in described copper lenticular wire cross section is 2.5mm, and minor face is 1.0mm.
aforesaid in the extraordinary composite enameled wire of automobile engine motor, described compound enamelled coating comprises the polyester-imide enamelled coating and polyamidoimide enamelled coating that arrange from the inside to the outside, and the thickness proportion of polyester-imide enamelled coating and polyamidoimide enamelled coating is 6:4.Arranging like this can improve thermal endurance class, insulation property and paint film toughness, and has higher impact resistance.
aforesaid in the extraordinary composite enameled wire of automobile engine motor, the thickness of described compound enamelled coating is 0.065mm ~ 0.075mm.
compared with prior art, enamelled wire heart yearn of the present invention have employed copper lenticular wire, under same cross-sectional amasss condition, compared to traditional enamel-cover circle line to occupy space less, use during the shape in the present invention and can save space 9-12%.Under identical winding space condition, enamelled wire of the present invention is used to improve a lot than the coil copper factor of round enamelled wire, its copper factor can reach more than 95%, enameled sheet wire application solves the problem that coil copper factor is difficult to improve for a long time for this reason, such resistance just reduces, electric capacity is just larger, just can meet the requirement of bulky capacitor high capacity use occasion better.And the enamelled wire of this applicability improves kelvin effect greatly, the loss of high-frequency current is reduced a lot, be more suitable for the appliance applications of high frequency environment.
and in same sectional area situation, the present invention has larger surface area, its area of dissipation is corresponding increase as much also, and radiating effect can significantly improve.When coiling, arrangement is also tightr, and line gap is less than the round line of enamel-cover, and when coil bears big current, coil vibrations can be less, and noise is lower.
Accompanying drawing explanation
fig. 1 is structural representation of the present invention.
being labeled as in accompanying drawing: 1-copper lenticular wire, 2-polyester-imide enamelled coating, 3-polyamidoimide enamelled coating.
Embodiment
below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
embodiment.For an extraordinary composite enameled wire for automobile engine motor, as shown in Figure 1: comprising cross section similar is square copper lenticular wire 1, and copper lenticular wire 1 is provided with fillet, and radius of corner is 0.5 times of the narrow limit of copper lenticular wire 1; Described copper lenticular wire 1 is outside equipped with compound enamelled coating.The long limit in described copper lenticular wire 1 cross section is 2.5mm, and minor face is 1.0mm.Described compound enamelled coating comprises the polyester-imide enamelled coating 2 and polyamidoimide enamelled coating 3 that arrange from the inside to the outside, and the thickness proportion of polyester-imide enamelled coating 2 and polyamidoimide enamelled coating 3 is 6:4.The thickness of described compound enamelled coating is 0.065mm ~ 0.075mm.
through detecting, enamelled wire springback angle of the present invention is no more than 5 degree, and percentage elongation can reach 30%, and puncture voltage is more than 2000V.
when carrying out tack test, result is as follows:
under the diameter of the rod of 4 times of copper lenticular wire narrow limit sizes, compound enamelled coating does not ftracture;
under the diameter of the rod of 4 times of copper lenticular wire broadside sizes, compound enamelled coating paint film does not ftracture;
minimum thermal impact temperature should be greater than 220 DEG C;
other indexs should meet GB/T7095.6-2008 standard related request.
