Patent ID: 8499910

Claim:
A device for inductive transmission of electric energy to or from a mobile object which is at a standstill or in motion on a roadway or rail and includes a load and/or energy store, said device comprising: a floor inductor associated to the roadway or rail and having a plurality of first induction coils which are arranged along the roadway or rail and connected to a power source and which have a magnetically conductive iron core for generating a magnetic field directed to the mobile object; and an inductive wheel attached to the mobile object, said inductive wheel including a fixed second induction coil with a magnetically conductive iron core, magnetically conductive wheel disks connected on both sides to the iron core and directed toward the roadway or rail, and elastic, magnetically conductive tires rotating with the motion of the object and associated to the wheel disks for contacting the roadway in the absence of an air gap and for ensuring a low-loss magnetic flux.
