Transponder system for non-contact inductive power transmission transfers power from a static side with a reading-coil on a stator onto a rotating side with a transponder coil on a spindle

摘要

A reading-coil's (2) medium (5), e.g. a stator, is made from material with good electrical conductivity and low magnetic permeability like aluminum, and/or, in the area of a transponder coil (4) in the inner periphery of the stator there is a layer made from a material with magnetically high permeability.
