Abstract
A method of inductive power transmission by a transmitter and a receiver of an electrically operated device, the transmitter having at least one transmitter coil and the receiver having at least one receiver coil, a control for the power to be transmitted is provided in the transmitter, a minimum power is transmitted by the transmitter through the control at the start of a power transmission, the minimum transferring power is sufficiently dimensioned to activate a controller of the receiver of the electrically operated device. By influencing the field of the transmitter coil, the controller supplies data packets to the control that contain information about the electrically operated device so that an optimal power adapted to the power class of the device is transmitted by the transmitter.
