Wave energy converter with energy source for actuator

A wave energy converter comprises a rotor 4 which is driven by wave movement relative to a stator 18. The rotor 4 has a vane 3 which is driven by wave movements. The angle of the vane 3 is controlled by an actuator 5, which is powered by an energy source. The energy source may comprise a generator w...

Zusammenfassung:	A wave energy converter comprises a rotor 4 which is driven by wave movement relative to a stator 18. The rotor 4 has a vane 3 which is driven by wave movements. The angle of the vane 3 is controlled by an actuator 5, which is powered by an energy source. The energy source may comprise a generator with permanent magnets 10b mounted on the stator and coils 10a on the rotor. Magnets 10b may be supplemented or replaced by electromagnets, e.g. to supply power when the rotor is not moving. Power is therefore supplied to the rotor without requiring slip-rings. A Flettner rotor may be used in place of vane 3, in which case the actuator controls the rotational speed for the Flettner rotor. The main generator 40, 41 may be positioned alongside the power supply to the rotor.
