  • Patent number: 6781270
    Abstract: An apparatus for producing magnetically induced movement of a second member in relation to a first member. The apparatus includes a first member having at least one perimeter magnet disposed thereon. The first member and at least one perimeter magnet are pivotable in relation to an axial member central of the first member. A second magnet is disposed central of the at least one perimeter magnet, with the second magnet disposed on a second member that is reciprocatable in relation to the first member as the second magnet is alternately attracted and repelled by magnetic forces of the at least one first magnet, and is also moved by gravitational force. Additional perimeter magnets and axial magnets are disposed in relation to the at least one perimeter magnet and the second magnet to convert motion of the first member into movement of the second member for recreational and energy conversion applications.

  • Publication number: 20040140722
    Abstract: A non-linear magnetic harmonic motion converter apparatus for transferring non-linear motion into rotational motion for producing work from an interaction of at least two magnetic fields. An axial shaft is disposed in rotating relationship with at least one gimbal supported magnet that reciprocates in relation to the axial shaft. At least one rotor magnet is disposed to rotate in relation to the axial shaft in response to non-linear movement of the at least one gimbal supported magnet. A plurality of rotor magnet units may be proximally disposed to rotate about separate axial shafts, with each rotor magnet unit having a rotor magnetic field influenced by the non-linear movement of the at least one gimbal supported magnet disposed proximal to each rotor magnet unit. Movement of the each gimbal supported magnet creates repulsion and attraction of each respective rotor magnet, with inducement of axial shaft rotation, thereby producing rotational movement that is harnessed to perform work.

  • Publication number: 20040061387
    Abstract: An apparatus for providing commutation for a direct current motor. The commutator has a magnet attached to a pivoting member and means for making and breaking at least one electrical circuit. The commutator magnet interacts with a magnet attached to the rotor. The rotor magnet can be either an independent magnet or one that also provides the motive force for causing the rotor to rotate. When the rotor magnet is adjacent the commutator magnet, the commutator changes state, thereby energizing a stator coil. The commutator has minimal moving parts and avoids the wear and maintenance problems of a conventional brush commutator.

At least one rotor magnet is disposed to rotate in relation to the axial shaft in response to non-linear movement of the at least one gimbal supported magnet. A plurality of rotor magnet units may be proximally disposed to rotate about separate axial shafts, with each rotor magnet unit having a rotor magnetic field influenced by the non-linear movement of the at least one gimbal supported magnet disposed proximal to each rotor magnet unit. Movement of the each gimbal supported magnet creates repulsion and attraction of each respective rotor magnet, with inducement of axial shaft rotation, thereby producing rotational movement that is harnessed to perform work.

  • Publication number: 20020167236
    Abstract: A linear magnetic harmonic motion converter apparatus for transferring linear motion into rotational motion for producing work from an interaction of at least two magnetic fields. An axial shaft and a perimeter frame member are disposed in sliding or pivoting orientation. The frame member includes at least one perimeter magnet positioned to provide a first magnetic field moved between different positions in response to external forces on the frame member. The first magnetic field reciprocates parallel to a longitudinal axis of the frame member that is aligned with the axial shaft. One or a plurality of rotor magnets are orientated proximal to the axial shaft to provide a second magnetic field that is attracted or repulsed by the first magnetic field. Movement of the perimeter magnet creates repulsion and attraction of the rotor magnets, with inducement of axial shaft rotation, thereby producing rotational movement that is harnessed to perform work.
