Summary Of The Invention

In view of the above-described problems, the object of the present invention is to provide a magnetic rotating apparatus in which rotational energy can be efficiently obtained from the permanent magnet with a minimum amount of electrical energy, and in which rotation control can be carried out relatively easily.

According to one aspect of the present invention, there is provided a magnetic rotating apparatus comprising a rotating shaft; a rotor which is fixed to the rotating shaft and which has disposed thereon permanent magnet means and means for balancing rotation, the permanent magnet means being disposed such that a plurality of magnetic poles of one (or first) polarity type is arranged along an outer peripheral surface in the direction of rotation, and a plurality of magnetic poles of the other (or second) polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; electromagnet means, which is disposed facing this rotor, for developing a magnetic field which faces the magnetic field of the permanent magnet means of the rotor and detecting means for detecting rotating position of the rotor to allow the electromagnet means to be energized.

According to another aspect of the present invention, there is provided a magnetic rotating apparatus comprising a rotating shaft a rotor which is fixed to the rotating shaft and which has disposed thereon a plurality of permanent magnets and balancers for balancing rotation, the permanent magnets being disposed such that one magnetic polarity type is arranged along an outer peripheral surface in the direction of rotation and the other magnetic polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; an electromagnet, which is disposed facing this rotor, for developing a magnetic field which produces the other magnetic polarity type on the facing surface; and energizing means for intermittently energizing the electromagnet means from where the leading permanent magnet, based on the rotation of the rotor, passes the facing surface of the electromagnet in the direction of rotation.

According to still another aspect of the present invention, there is provided magnetic rotating apparatus comprising a rotating shaft; a first rotor which is fixed to the rotating shaft and which has disposed thereon permanent magnet means and means for balancing rotation, the permanent magnet means being disposed such that a plurality of magnetic poles of the second polarity type is arranged along an outer peripheral surface in the direction of rotation, and a plurality of magnetic poles of the first pole type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line; a second rotor which rotates along with the first rotor and is fixed to the rotating shaft, having disposed thereon a plurality of permanent magnets and balancers for balancing rotation, the permanent magnets being disposed such that one magnetic polarity type is arranged along an outer peripheral surface in the direction of rotation and the other magnetic polarity type arranged along an inner peripheral surface, with each pair of corresponding magnetic poles of one and the other polarities obliquely arranged with respect to a radial line a first and a second electromagnet means, which are magnetically connected and disposed facing the first and second rotors, respectively, for developing a magnetic field which faces the magnetic field of the permanent magnet means of the first and second rotors; and detecting means for detecting rotating position of the rotors to allow the electromagnet means to be energized.

The nature, principle and utility of the invention will become more apparent from the following detailed description when read in conjunction with the accompanying drawings.

Renewable Energy

Renewable Energy

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.
