ABSTRACT:
A device for efficient transmission of electrical energy and/or information is built in the manner of a rotary transformer. The cores of this device are made of ferromagnetic rings of a U-shaped cross section of soft iron, or of soft iron core stacks of annular or hollow cylindrical shape, the ring-shaped or hollow cylindrical sheets typically being unslotted. There can be several coil sets within such a device; in this way several channels can be made available for parallel transmission of electrical energy and/or information.
