Rotary transformer for the contactless transmission of electrical energy

摘要

Rotary transformer for the contactless transmission of electrical energy,a first rotary wherein the rotary transducer by means of support part and a second rotary by means of support part which is of relatively to the first rotary by means of support part is rotatably arranged,the first rotary support part by means of a primary winding and the second rotary support part by means of a coil,the coil and a coil core has in the secondary windings,each secondary winding is designed as a toroidal winding,in particular wherein each secondary winding inductively coupled to the primary coupling,the second rotary support part by means of a mechanical support part, in particular annular web, which is arranged on a larger radial distance as the coil,with the coil radially inside of the mechanical support part in such a way that is arranged to centrifugal force acting on the coil to the mechanical support part is derived, in particular on the secondary windings centrifugal force acting on it, via the coil core to the mechanical support part is derived,where in a radially outside of the mechanical support part is arranged an electronic circuit.
