ELECTROMAGNETIC GEAR Russian patent published in 2014 - IPC H02K16/02 H02K51/00 

FIELD: electricity.

SUBSTANCE: in electromagnetic gear containing a housing with mounted stator with multiphase winding coupled to the voltage source as well as the first and second rotors rigidly fixed at the input and output shafts respectively, according to the invention the stator winding is coupled to the voltage source through a regulated frequency converter and placed in grooves of the stator inner surface thus forming poles, while the first rotor is mounted coaxially with stator and fixed rigidly to the input shaft end, is designed as a squirrel cage, which rods are inserted into the rings made from non-magnet material, they have prismatic shape and form teeth of the first rotor, and the second rotor is placed inside the first one and made as a toothed magnetic core with the teeth number z₂, equal to z₂ = (z₁ - p₁), where z₁ - number of teeth of the first rotor; p₁ - number of pole pairs of the stator winding; while the stator, teeth of the first rotor and the second rotor are laminated and made from ferromagnetic thin steel plates.

EFFECT: preserving the possibility of regulation of reduction coefficient at simultaneous providing of design simplification.
