Abstract
An inductive rotary joint for non-contact transmission of electrical energy between a stationary part and a rotating part of the rotary joint comprises a power generator for generating an alternating voltage or an alternating current, which feeds a load by means of a rotatable power transmitter. An electrical parameter on the primary side of the power transmitter is determined with a measurement means, and from this, the condition of another electrical parameter at the load is approximated by means of a functional unit. Regulation of the power generator is effected with this approximated value.
