Embodiment Construction

[0038] Referring now to the accompanying drawings, figure 1 A stator 100 is shown with a coil structure 106 mounted thereon according to the invention. The stator 100 comprises a magnetic core 102 on which are arranged eight teeth 104 also referred to as poles or flux guiding elements. A coil structure 106 is mounted on the magnetic core 102 such that the teeth 104 extend through the opening 108 at the coil structure 106 disposed around the opening 108, the coil structure 106 comprising a coil of wire wound or a flat conductive trace integrated into a printed circuit board. The wire 110 , which is here in particular formed, is wound helically around the opening and thus around the tooth 104 .

[0039] In the illustrated embodiment, the flat conductive traces 110 are shaped to form a conductive winding around each tooth 104 . The flat conductive trace 110 is fabricated on a flexible electrically insulating carrier 112, as from figure 1 obtainable. When the stator 100 with...

Abstract

The present invention relates to an electromagnetic coil structure for being mounted on a magnetic core. Such a magnetic core is for instance a part of a rotating electric machine or of a magneto electronic angle sensor. The present invention further relates to a belonging magnetic core and to a magneto electronic angle sensor, in particular a reluctance resolver. Furthermore, the present invention relates to a method for fabricating such an angle sensor. The coil structure (106) comprises at least one electrically conductive winding formed as a flat conductive track (110), and at least one flexible electrically insulating carrier (112) for carrying said winding. Said coil structure has at least one opening (108) for receiving a magnetic flux guiding element (104) of said core. The circumferential surface of the core whereto said electromagnetic coil structure (106) is mounted has a polygonal shape.

Description

technical field [0001] The invention relates to an electromagnetic coil structure for mounting on a magnetic core. Such a magnetic core is, for example, part of a rotating electrical machine or a magnetoelectric angle sensor. The invention further relates to the associated magnetic core and magnetoelectric angle sensor, in particular to a reluctance resolver having a stator constructed according to the principles of the invention. Furthermore, the invention relates to a method for producing such an angle sensor. Background technique [0002] Although the principles of the present invention are applicable to a wide variety of systems using coil structures mounted on magnetic cores, in the following the field of application of reluctance resolvers will primarily be considered. In particular, reluctance resolvers as shown in German patent applications DE 102010004887.9 and DE 102009021444.5 can be improved by employing the principle according to the invention. [0003] The r...
