Abstract:
1. Inductive rotary joint, comprising: an inverter; an inductive rotary coupler having a primary winding and a secondary winding; in which the primary winding of the inductive rotary coupler is fed by the inverter via a first line, and energy transmitted by the inductive rotary coupler is delivered to a load from a secondary winding via a second line; wherein at least one of the first and second lines comprises at least two coaxial lines, each having an outer conductor and an inner conductor; the outer conductors are interconnected in an electrically conductive manner along a major part of their length; and each of the inner conductors is supplied by the inverter with voltages, with a sum of the voltages supplied to the inner conductors being substantially equal to zero.
