Electrical energy generating device e.g. wave energy converter has stator that is connected to generator housing, when variable force is smaller than restoring force, and rope-like component is rolled opposite to rolling direction

摘要

The device (100) an electric generator whose rotor (140) is connected to a generator shaft (120), via a free-wheel (142), so that rotation of the rotor in a rolling direction of the shaft is accelerated, if variable force is greater than restoring force, and the rotor is continued to rotate in an unwinding direction. A stator (150) of the electric generator is connected to a generator housing (110), when variable force is smaller than restoring force, and a rope-like component (130) is rolled opposite to a rolling direction. The device has the generator shaft that is rotatably arranged in the generator housing. One end of the rope-like component is attached to the shaft, and other end of component is connected with a counter mass portion (102) directly or indirectly. The shaft is adapted to exert restoring force on the component, so that the component is wound on shaft. Force acted on housing is made smaller than restoring force, if variable of the counter mass portion is directed away, so that component is rolled from shaft. The force acted on the housing is made greater than restoring force, if variable of counter mass portion is faced away. An independent claim is included for a method of generating electric energy.
