  • Publication number: 20190028014
    Abstract: A magnetic cycloid gear assembly includes an outer magnet drum comprising a plurality of outer drum magnets having a first number of magnetic pole pairs. The assembly also includes a first inner magnet drum comprising a first plurality of inner drum magnets having a second number of magnetic pole pairs. The assembly also includes a second inner magnet drum comprising a second plurality of inner drum magnets having a third number of magnetic pole pairs. Each of the first and second inner drums has an inner magnet drum axis that is offset from an outer magnet drum axis. The assembly further includes a plurality of drive mechanisms, each mechanism being operatively coupled to each of the first and second inner drums. The plurality of drive mechanisms is configured to drive each of the first and second inner magnet drums to revolve in an eccentric manner about the outer drum axis.

  • Patent number: 10008912
    Abstract: A magnetic drive device may comprise a stator comprising a plurality of windings for generating a first number of magnetic pole pairs and a rotor comprising a plurality of permanent magnets for generating a second number of magnetic pole pairs that differs from the first number of magnetic pole pairs. The magnetic drive device may further comprise a plurality of free-spinning interpole elements disposed within an air gap between the stator and the rotor. The interpole elements may produce a magnetomotive force and harmonically couple the magnetic pole pairs of the stator with the magnet pole pairs of the rotor.

  • Patent number: 9593753
    Abstract: A magnetic gear may comprise a first gear member comprising a plurality of permanent magnets arranged to have a first number of magnetic pole pairs and a second gear member positioned relative to the first gear member. The second gear member may comprise a plurality of individually rotatable magnetized elements each driven and synchronized with one another to selectively generate a second number of magnetic pole pairs that differs from the first number of magnetic pole pairs. The magnetic gear may further comprise a plurality of interpole elements positioned between the first and second gear members. The plurality of interpole elements may be disposed to harmonically couple the magnetic pole pairs of the first gear member with the magnetic pole pairs of the second gear member for each selectively generated second number of magnetic pole pairs.
