Magnetic gear Gear

all cogs of each gear component of magnetic gears act constant magnet periodic alternation of opposite magnetic poles on mating surfaces. gear components mounted backlash capability similar other mechanical gearings. although cannot exert force traditional gear, such gears work without touching , immune wear, have low noise , can slip without damage making them reliable. can used in configurations not possible gears must physically touching , can operate non-metallic barrier separating driving force load. magnetic coupling can transmit force hermetically sealed enclosure without using radial shaft seal, may leak.
