ELECTROMECHANICAL ACTUATING ELEMENT OF AES ORIENTATION SYSTEM Russian patent published in 2018 - IPC B64G1/00 

FIELD: electronic equipment.

SUBSTANCE: invention relates to the electrical equipment of the spacecraft orientation and stabilization systems (AES). Electromechanical actuating element (EMAE) contains flywheel (1) with rotor (2) of reversible electric motor of the "pole" ("claw") type having stator (6) with three-phase winding (7). Permanent magnet (3) is separated from the "claws" of poles (4) by nonmagnetic material (5). Stator is fixed to the axis in the form of two semi-axes (8) fixed in end caps (9). Axis and covers are made of non-magnetic material. Stator (6) is separated from rotor (2) by non-magnetic working gap (10). EMAE also contains two permanent magnets (11) with pole pieces (12) and yokes (13) made of soft magnetic material fixed to covers (9). Between rotor (2) and pole pieces (12) auxiliary gaps (14) are formed. Magnets (3) and (11) made of a material with high-coercivity characteristics (NdFeB) face gaps (14) with the same poles. Flywheel (1) is made of a composite material, which excludes the possibility of currents flowing in it (causing a braking torque).

EFFECT: technical result is the provision of long-term space operation of AES equipped with the proposed EMAEs, and the orientation of AES with the least energy consumption.
