Device for inductive power supply and guidance of a moving object, with a primary inductance element extending as a conductive loop along a path provided for the object. A secondary inductance element is arranged on the object and can be coupled magnetically with the primary inductance element for power transmission. Several receiver inductance elements are arranged on the object and output measurement signals dependent on the magnetic field of the primary inductance element. An evaluation device determines a measure for the position of the object with reference to the conductive loop from the measurement signals. A regular arrangement of receiver inductance elements is provided, which extends on the object at least perpendicular to its direction of motion. The receiver inductance elements are simultaneously also connected to a data receiver device, which contains a way for extracting a data signal from the output voltage of at least one of the receiver inductance elements. At least one data line, which exhibits inductive coupling with at least one of the receiver inductance elements sufficient for transmitting a data signal while the object is moving, is arranged along the path provided for the object.
