摘要： A coil module comprises a carrier which has a polygonal basic shape with four to twelve corners and comprises a magnetic material. A coil is arranged on the carrier. The polygonal basic shape is rotationally symmetrical with an angle of 360°·2 divided by the number of corners. To produce a coil assembly, a plurality of coil modules can be connected to each other. This makes it possible to produce an efficient coil assembly for wireless electromagnetic energy transmission in a simple and flexible manner.

摘要： An inductor, in particular for magnetically coupled energy transfer, includes a coil carrier on which a first coil and a second coil are arranged. The second coil has an outer diameter D2 that is greater than an outer diameter D1 of the first coil. A magnetic core surrounds a longitudinal center axis of the first coil. The first coil is operated with a first operating frequency in a first power range, whereas the second coil is operated independently of the first coil with a second operating frequency in a second power range. As a result applications can be run in a simple and flexible manner in a low-power range and in a high-power range.

摘要： A coil arrangement for the wireless electromagnetic transmission of energy includes a carrier which forms a main direction of extent. On the carrier element, are attached in succession in the main direction of extent and connected to one another. The carrier element comprises a ferrite material and at least one desired parting location which is designed as a perforation and/or notch arrangement. The coil arrangement can be easily adapted in a flexible way to a rotatable component and attached thereto. This makes easy wireless electromagnetic transmission of energy possible.
