1. A system for a machine having a large number of actuators, comprising:

  • a machine having a large number of actuators;

    a medium-frequency oscillator;

    a process computer for said machine;

    a central transmission device for transmitting radio signals, said transmission device connected to said process computer; and

    at least one primary winding for producing a medium-frequency magnetic field for applying said actuators with electrical power without using wires, said primary winding being fed from said medium-frequency oscillator;

    each one of said actuators having a plurality of mutually orthogonal secondary windings suitable for drawing power from the medium-frequency magnetic field; and

    each one of said actuators being equipped with a receiving device independent of said secondary windings for receiving the radio signals from said central transmission device.
