Abstract
With an aim of minimizing excitation losses in electric machines having electrically excited and displaceable secondary parts, bi-directional inductive transmission of energy is carried out by a rotating inductive transmission device. An associated electronic system for the bi-directional transmission of power and/or energy, is provided. Advantageously, super-conductive inductance is present wherein the flow is introduced. It is possible to excite by supplying energy to the stator and to also de-excite by removing energy without converting the power into heat on the rotor by applying a bipolar tension.
