Patent ID: 8749080

Claim:
An electric operating system for operating at least one electric equipment article for a work machine, the work machine comprising a combustion engine defining a combustion engine space, comprising (i) a flywheel generator for generating electric power needed for the operation of the at least one electric equipment article, wherein the at least one electric equipment article is an attachment device, that is attachable to, or arrangeable at, the work machine, or wherein the at least one electric equipment article is an auxiliary device which is electrically drivable by an electric motor, the flywheel generator being integrated into the combustion engine space; (ii) a power electronic device connected to the output of the flywheel generator for adapting a voltage level provided by the flywheel generator to a voltage level required for the operation of the at least one electric equipment article; and (iii) a connector device connectable to the power electronic device and the at least one electric equipment article when the at least one electric equipment article is attached to, or arranged at, the work machine for providing the at least one electric equipment article with electric power at the adapted voltage level, wherein the work machine con rises a combustion engine and the flywheel generator is arranged on an output shaft of the combustion engine, wherein an energy buffer is coupled to the flywheel generator and/or the power electronic device, and wherein the energy buffer is chargeable by the flywheel generator separate from a charging system of a starter battery of the combustion engine.
