  • Electric generator having stationary induction coils
    Patent number: 4798986
    Abstract: An electric generator having a plurality of circumferentially spaced stationary induction coils, a rotatable armature of permanent magnets on a disc, magnetically conductive core in each said coil extending outwardly from said coil and terminating closely adjacent to the faces of the magnets as the disc is rotated.
    Type: Grant
    Filed: April 11, 1988
    Date of Patent: January 17, 1989
    Inventor: Berry E. Smith, Jr.
  • Electric generator for inducing current in the field coil
    Patent number: 4792711
    Abstract: An electric generator having a stationary field coil, a rotatable armature of permanent magnets, and between the coil and the armature a stationary cylindrical cage of strips of a conductor of magnetic flux extending across the coil and the magnets, the magnets being mounted on a wheel or disc structure adjacent to the field coil.
    Type: Grant
    Filed: May 27, 1987
    Date of Patent: December 20, 1988
    Inventor: Berry E. Smith, Jr.
  • Electric generator for inducing current in the field coil
    Patent number: 4719380
    Abstract: An apparatus including a stationary field coil wound with copper wire; a rotatable armature comprising a plurality of lengthwise rows of magnets, each row being of a single polarity which is opposite from the polarity of the next adjacent rows; a rotatable sleeve positioned between the field coil and the armature and spaced apart from each, the sleeve comprising a plurality of lengthwise strips of material that attract magnetic flux spaced apart from each other by a strip of material that is transparent to magnetic flux, and means to rotate the armature or the sleeve while the other remains stationary.
    Type: Grant
    Filed: August 4, 1986
    Date of Patent: January 12, 1988
    Inventors: Berry E. Smith, Jr., Nathan N. Sharron
  • Electric generator with two rotors
    Patent number: 4612470
    Abstract: An apparatus including a stationary field coil wound with alternating insulated copper wire and insulated steel wire; a rotatable armature comprising a plurality of lengthwise rows of magnets, each row being of a single polarity which is opposite from the polarity of the next adjacent rows; a rotatable sleeve positioned between the field coil and the armature and spaced apart from each, the sleeve comprising a plurality of lengthwise strips of material that attract magnetic flux, spaced apart from each other by a strip of magnetic material that is transparent to magnetic flux, and means to rotate the armature or the sleeve while the other remains stationary.
