SEABASED WAVE POWER GENERATOR


Seabased's wave power technology utilizes the water motion in waves to directly drive the wave power plants. The active element is a unique directly driven permanent magnet linear generator. The generator is specially designed to take advantage of the slow movement of the waves that is transferred to it via a buoy (point absorber) on the ocean surface.The buoy action is transferred directly to the generator with no intermediate mechanical gearing since the generator is optimized to output high power even at slow speeds.The movement of the waves (about 15 wave cycles/min) causes the translator (corresponding to the swiftly turning rotor of a conventional generator) to move up and down within the stator, thus converting the kinetic energy of the wave to electric energy. Very powerful neodymium-iron-boron magnets are mounted on the translator. They create an alternating magnetic field which penetrates the stator windings. The stroke length of the translator is limited by end stops at the top and bottom.
