Each actuator has at least one secondary winding that is suitable for drawing power from a medium-frequency magnetic field.
Claims13
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 supplying 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 orthogonal secondary windings that are suitable for drawing power from the medium-frequency magnetic field;
- and
- each one of said actuators being equipped with a receiving device for receiving the radio signals from said central transmission device.
