ELECTRIC MACHINE WITH MULTIPLIER Russian patent published in 2016 - IPC F16H25/06 H02K7/116 F03D7/04 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering, namely to electric machines with wave transmission. Electric machine with multiplier comprises housing 10, stator 3, rotor 4 and wave transmission in multiplier mode with rolling bodies 7, wherein multiplier is arranged coaxially inside electric machine rotor. Multiplier comprises rigid wheel 5 with outer toothed profile, which is electrical machine axis, separator 6 with rolling bodies attached to electrical machine housing, wave former 8, made as multiple-disk, with output shaft in form of cylinder, which outer surface is an electric machine rotor windings base, and internal is made of circular grooves of the same diameter, which number is equal to number of discs. Centers of adjacent circular grooves are shifted relative to longitudinal axis at the same eccentricities, oriented in opposite sides, wherein each of these grooves has groove to accommodate rollers making package bearings, which cages are discs, contacting with rolling bodies located in separator.

EFFECT: technical result consists in reduction of high capacity electric machine with multiplier dimensions and weight, higher efficiency and lower cost of its production.
