Coil arrangement and model car having such coil arrangement

Abstract

A model car with a coil arrangement having at least one substrate and at least one first coil portion and a second coil portion, wherein the substrate, which is manufactured from an electrical insulating material, has a basic shape extending in a planar manner and having an upper side and an underside opposite the upper side, wherein at least the first coil portion and the second coil portion form a coil winding, wherein the first coil portion is arranged on the upper side of the substrate and the second coil portion is arranged on the underside of the substrate.

1 . A model car including a coil arrangement, said coil arrangement having at least one substrate and at least one first coil portion and a second coil portion, wherein the substrate, which is manufactured from an electrically insulating material, has a basic shape extending in a planar manner with an upper side and an underside opposite the upper side, wherein at least the first coil portion and the second coil portion form a coil winding, wherein the first coil portion is arranged on the upper side and the second coil portion is arranged on the underside of the substrate. 
     
     
         2 . The model car of  claim 1 , wherein the substrate has a ferrite core. 
     
     
         3 . The model car of  claim 1 , wherein the substrate has a first circuit board portion and a second circuit board portion, wherein an upper side of the first circuit board portion forms the upper side of the substrate and an underside of the second circuit board portion forms the underside of the substrate. 
     
     
         4 . The model car of  claim 3 , including connecting lines extending through the first circuit board portion and the second circuit board portion in order to connect the first coil portion with the second coil portion electrically. 
     
     
         5 . The model car of claim wherein an underside of the first circuit board portion is arranged on an upper side of the ferrite core and an upper side of the second circuit board portion is arranged on an underside of the ferrite core. 
     
     
         6 . The model car of  claim 1  wherein coil portions form at least three to eight, in particular five coil windings. 
     
     
         7 . The model car of  claim 1 , wherein a screw vector of the coil arrangement lies substantially within the plane of the substrate. 
     
     
         8 . The model car of  claim 1 , wherein the substrate has a first direction of extension which extends between the two coil portions, a second direction of extension (I) which extends at right angles to the first direction of extension (I) and a third direction of extension (III) which extends at right angles to the first direction of extension (I) and to the second direction of extension (II), wherein a screw vector (S) of the coil arrangement extends substantially in the direction of the second direction of extension (II) and/or the third direction of extension (III). 
     
     
         9 . (canceled) 
     
     
         10 . The model car of  claim 2 , wherein the substrate has a first circuit board portion and a second circuit board portion, wherein an upper side of the first circuit board portion forms the upper side of the substrate and an underside of the second circuit board portion forms the underside of the substrate. 
     
     
         11 . The model car of  claim 4  wherein coil portions form at least three to eight, in particular five coil windings. 
     
     
         12 . The model car of  claim 11 , wherein the substrate has a first direction of extension (I) which extends between the two coil portions, a second direction of extension (II) which extends at right angles to the first direction of extension (I) and a third direction of extension (III) which extends at right angles to the first direction of extension (I) and to the second direction of extension (II), wherein a screw vector (S) of the coil arrangement extends substantially in the direction of the second direction of extension (II) and/or the third direction of extension (III).
