Abstract

A crusher includes an internal combustion engine, a crusher unit and a drive train connecting the internal combustion engine and the crusher unit. The drive train includes a motor coupling, a crusher unit coupling and a motor generator. The motor generator includes a motor rotor and a motor stator. The motor rotor includes a motor generator shaft coupled to both an output end of the motor coupling and an input end of the crusher unit coupling in a rotationally fixed manner. The motor generator has a motor mode of operation in which the motor generator provides mechanical work for driving the crusher unit. The motor generator has a generator mode of operation in which the motor generator is driven by the internal combustion engine to generate electrical power.
