Description

AREA OF INVENTION

The The present invention relates to an electrotechnical component which at least one coil-like winding of an electrical conductor includes.

Electrical Components in which coil-like windings with one or more Windings or corresponding electric coils are used, are widely used. In particular through the use of electric motors in many areas of technology to drive a wide variety of Components, such components are widely used. So have to for example, in motor vehicles or aircraft by electric motors diverse Mastered drive tasks become. this leads to In addition, such vehicles due to the high metal content, the electrotechnical coils or corresponding coil-like windings due to the metallic conductors contained in the winding, have a high weight and thus the requirement of lightweight construction unfavorably being affected.

TASK OF THE INVENTION

It is therefore an object of the present invention, a generic electro-technical component ready to provide, which is a weight reduction of the components allows. About that In addition, the production of such components should be simple and effective possible be.

BEING THE INVENTION

These Task is solved with an electrotechnical component having the features of the claim 1. Advantageous embodiments are the subject of the dependent claims.

According to the present Invention is an electrotechnical component with at least one coil-like winding of an electrical conductor proposed in which the electrical conductor by a conductive plastic is formed. By using a conductive plastic as an electrical Head for the turns of a coil or the coil-like winding of a corresponding electrotechnical component can effectively reduce the weight be reduced. In particular, there is also a simplification the production and increase of production efficiency, because the processing and manufacturing temperatures corresponding Plastics require a low energy input and use simpler equipment due to the lower working temperatures enable. Furthermore the scarce metal resources are spared.

Although electrically conductive plastics are already known from the prior art, such as the EP 435 044 A2 or the publication "Application Potentials for Conductive Polymers" by JW Schulze and H. Karabulut in Galvanotechnik 8/2005, Eugen G. Leuze Verlag, page 1796 ff .. However, the applications of these materials are usually limited to areal applications, such as catalyst layers However, the present invention has shown that conductive plastics or polymers can also be used effectively in mass-produced electrotechnical components such as electric coils or coil-type windings or the like for weight reduction.

Preferably is considered more conductive Plastic an intrinsically conductive Polymer used, which has high flexibility in terms of conditions of use guaranteed.

such intrinsically conductive Polymers (intrinsically conductive polymers ICP) may preferably selected from the group polyaniline, polypyrrole, polythiophene, polyethylenedioxythiophene, their derivatives and / or combinations thereof.

The intrinsically conductive Polymers (ICP's) exhibit besides their good conductivity values, in particular the conductivity values reach of metallic materials, in particular the possibility to be manufactured easily and effectively and to the corresponding ones use cases to be adapted. Especially against the conductive Plastics containing conductive fillers can be used the intrinsically conductive Polymers as a uniform material easier and better used become.

Alternatively, however, the electrically conductive plastic may be formed as a plastic in which carbon with graphite lattice structure in the form of carbon nanotubes is used as the conductive filler, which have a particularly good electrical conductivity and thus suitability as a filler. Furthermore, this material has a very low density of 1.3 to 1.4 g / cm ³ and a very good current capacity, which is estimated to be 1000 times higher than copper wires. Thus, such a material for the application of the present invention is predestined.

The electrically conductive Plastics or polymers are according to the invention in particular for electrical Coils, transformers, generators or electric motors used.

at a preferred embodiment is an electrical coil (inductance) or the winding of a Electric motor with an intrinsically conductive polymer on the base formed by Polyethylendioxythiopen, which has particularly favorable properties for technical Applications has.
