MAGNETIC GEARS, AND RELATED SYSTEMS AND METHODS

摘要

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.
