  • Patent number: 7148596
    Abstract: A magnetic rotating motor generator of the present invention comprises a rotating portion which is made of a non-magnetic substance whose periphery is provided with a group of permanent magnets tilted at a predetermined angle in an embedded manner; a group of electromagnets that are disposed adjacently to the rotating portion so as to oppose the group of permanent magnets; a positional sensor for detecting positions of the group of permanent magnets; a controller for applying an electric current to the electromagnet on the basis of a detected signal from the positional sensor; and a power generating section for obtaining power from a coil of the electromagnet. A rotation mode and a power generation mode are repeated, so that power generation is performed while a function as a motor is exhibited.

  • Patent number: 5594289
    Abstract: On a rotor which is fixed to a rotatable rotating shaft, a plurality of permanent magnets are disposed along the direction of rotation such that the same magnetic pole type thereof face outward. In the same way, balancers are disposed on the rotor for balancing the rotation of this rotor. Each of the permanent magnets is obliquely arranged with respect to the radial direction line of the rotor. At the outer periphery of the rotor, an electromagnet is disposed facing this rotor, with this electromagnet intermittently energized based on the rotation of the rotor. According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets. This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets.

  • Patent number: 4751486
    Abstract: The magnetic rotation apparatus of the present invention has first and second rotors rotatably supported and juxtaposed. The first and second rotors are connected so as to be rotatable in opposite directions in a cooperating manner. A number of permanent magnets are arranged on a circumferential portion of the first rotor at regular intervals, and just as many permanent magnets are arranged on a circumferential portion of the second rotor at regular intervals. Each permanent magnet has one magnetic polarity located radially outward from the rotors, and has the other magnetic polarity located radially inward toward the rotors. The polarity of each permanent magnet, which is located radially outward from the rotors, is identical. When the first and second rotors are rotated in a cooperating manner, the phase of rotation of the permanent magnets of one rotor is slightly advanced from that of the permanent magnets of the other rotor. One of the permanent magnets of one rotor is replaced with the electromagnet.
