8. A method for supplying power to a tool carried by an industrial robot, wherein a direct current is provided to a transmitting part of a power supply system comprising a first coil and a first converter, the direct current is converted by the first converter and the first coil for producing an alternating magnetic field, a second coil of a receiving part of the power supply system is arranged to produce by induction an alternating current from the magnetic field, and the alternating current is converted into a direct current by a second converter of the receiving part of the power supply system, the method comprising:
-
attaching the first coil to the industrial robot, attaching the second coil to the tool and detachable from the first coil, and arranging the first coil and the first converter in a resonance circuit, thereby increasing the current in the first coil thus producing an increased magnetic field. - View Dependent Claims (9, 11, 12, 13)
