Abstract
A wave energy conversion device includes a permanent magnet generator, a first driving component and a second driving component. The permanent magnet generator includes a stator structure and a rotor structure. The stator structure includes a stator body. The rotor structure includes a rotor body. The rotor body is disposed inside the stator body in a swinging manner or in a rotatable manner. The first driving component is coupled to the rotor structure. The second driving component is coupled to the stator structure. The wave energy conversion device of the present invention requires a low speed/angle of a swinging/rotating movement of the rotor body relative to the stator body to generate electricity, which facilitates electricity generation from wave energy.
