Abstract
The present invention provides a kind of for founding the high-performance enamel-cover flat type copper wire material of winding coil, and preparation method is as follows：The dry pot of graphite clay equipped with copper material is heated using resistance furnace, the temperature of copper material is increased to 800-1000 degrees Celsius, is separately added into rare earth composition to be adulterated at different temperature, is sufficiently stirred, carry out cold-drawn；The rare earth is as two or more in praseodymium, neodymium, promethium, samarium.The high-performance enamel-cover flat type copper wire material for being used to stand winding coil of the invention, is doped into rare earth composition, conductivity with higher.
Description
Technical field
The present invention relates to a kind of for founding the high-performance enamel-cover flat type copper wire material of winding coil, belongs to electrical technology field.
Background technique
Motor technologies are for electric car（EV）And hybrid electric vehicle（HEV）Development play a supportive role.Motor it is main
Component --- coil currently makes constant progress by axle center of duty ratio.Duty ratio be actual wire sectional area with electric current
Shared ratio in sectional area when vertical plane cutting coil.If duty ratio improves, it can realize that size is small, weight
Light and strong motor.If with round wire coiling, can not just expect to obtain how high duty ratio, using flat vertical
Winding coiling is needed using the biggish flat copper wire rod of aspect ratio, and previous enamel-cover material is typically all the polyester being coated with
And polyamide-imides（PAI）Equal insulating materials.It needs to dry after coating, film can be shunk after the drying.Line if round
If, shrinking can be relatively uniform, and flat wire will appear problem.It due to the contraction of film, that is, attracts each other, therefore very
More insulators can be gathered in the central portion of long side, and coating thickness is caused to increase.Corner parts are then tensed by surrounding, and film is caused to become
It is thin.When bigger in length and breadth, film cracking is even resulted in, to influence the insulating properties of wire rod.Early-stage study shows to close in conductive copper
Jin Zhong after suitable rare earth element is added, can be improved the intensity and wear-resisting property of copper material；In certain temperature（Such as 150 is Celsius
Degree or more）In the conductive copper material used, rare earth, which is added, can be improved its heat resistance and inoxidizability；In the copper wires of certain deep-draws
And in ultrafine wire material, rare earth, which is added, can obtain good cold plasticity.The resistivity of copper conductor influences the thermal losses of motor
Larger, while using rear-earth-doped improvement copper conductor mechanical property, the influence to resistivity is not yet very clear so far.
Summary of the invention
The purpose of the present invention is making up the blank of the prior art, it is flat to provide a kind of high-performance enamel-cover for founding winding coil
Copper wire material studies the rare earth doped influence to copper conductor electric conductivity.
The high-performance enamel-cover flat type copper wire material for being used to stand winding coil of the invention, preparation method are as follows：Utilize resistance
Furnace heats the dry pot of graphite clay equipped with copper material, increases the temperature of copper material to 800-1000 degrees Celsius, at different temperature
It is separately added into rare earth composition to be adulterated, is sufficiently stirred, cold-drawn is carried out；The rare earth is as in praseodymium, neodymium, promethium, samarium
It is two or more.
The high-performance enamel-cover flat type copper wire material for being used to stand winding coil of the invention, is doped into rare earth composition, has higher
Conductivity.
Specific embodiment
The high-performance enamel-cover flat type copper wire material for being used to stand winding coil of the invention, preparation method are as follows：Utilize resistance
Furnace heats the dry pot of graphite clay equipped with copper material, increases the temperature of copper material to 800-1000 degrees Celsius, at different temperature
It is separately added into rare earth composition to be adulterated, is sufficiently stirred, cold-drawn is carried out；The rare earth is as in praseodymium, neodymium, promethium, samarium
It is two or more.
