A configuration for producing electrical power from a magnetic field includes a three-dimensional winding configuration formed from a central core of a magnetic material on which at least three windings are fitted. The windings have winding axes each disposed at right angles to one another and intersecting at a common point. Each of the windings is connected to a rectifier. Each of the windings is, preferably, connected to a resonant capacitor to form a resonant circuit.

Configuration for producing electrical power from a magnetic field

A system for a machine, in particular an automated production machine, has a large number of proximity sensors. Each proximity sensor has at least one secondary winding that is suitable for drawing power from a medium-frequency magnetic field. At least one primary winding, which is fed from a medium-frequency oscillator, is provided for supplying the proximity sensors with electrical power without using wires. Each proximity sensor is equipped with a transmitting device that emits radio signals, which contain sensor information of interest, to a central receiving device that is connected to a process computer for the machine. A proximity sensor and a primary winding for this purpose are also proposed.
