Abstract
A hydroelectric turbine anchored in a body of water which produces electricity directly from its housing. The turbine is in and of itself a generator whose housing is its stator and whose blade it its rotor.
Claims18
A hydroelectric turbine comprising a rotor and three distinctly separate groups of magnets:
- a first group of magnets arranged to produce the magnetic field necessary to produce electricity;
- a second group of magnets arranged with similar poles facing each other to maintain alignment of the rotor;
- and, a third group of magnets arranged with similar poles facing each other to prevent rotor from being forced downstream by the force of the water against the rotor.
A hydroelectic turbine comprising:
- a stationary stator housing;
- a rotor comprising an outer rim, at least one blade and an inner rim, said rotor disposed within said stator housing and turned by downstream water flow;
- and
- a first group of magnets arranged to produce the magnetic field necessary to produce electricity;
- a second group of magnets arranged with similar poles facing each other to maintain alignment of said rotor within said stator housing;
- and a third group of magnets arranged with similar poles facing each other to prevent said rotor from being forced downstream and out of said stator housing by the downstream water flow.
