LOW-SPEED LINEAR MAGNETOELECTRIC GENERATOR WITH FLAT COILS (TILIMEG FC) Russian patent published in 2018 - IPC H02K35/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to magnetoelectric generators serving as autonomous power supplies driven by slow-speed systems, for example, micro HPPs installed on low-speed rivers with flow rates from 0.5 to 3.0 m/s and wind power plants operating in zones, where the average annual wind speed is from 1.5 to 4.5 m/s and can be used on traditional micro-HPPs with water flow rates exceeding 3.0 m/s, and wind turbines and an average wind speed of more than 4.5 m/s. Low-speed linear magnetoelectric generator with flat square coils contains a detachable housing consisting of a cylindrical body with a flange and a cover. Two cylindrical rings with square cells located along their periphery, for the installation of mini-linear magnetoelectric generators, hermetic tubular square non-magnetic bodies are filled with a light inert gas helium (He). Movable rectangular parallelepipedic permanent magnets with longitudinal magnetization have central longitudinal holes and are located with a minimum gap inside the sealed tubular square housings. Permanent magnets create magnetic cushions for moving rectangular parallelepipedic permanent magnets. Diameter of flat round permanent magnets with semicircular ends of the rotor is equal to the length of the diagonal of the tubular square case. Four parts of the annular holder of flat round permanent magnets are installed at the end along the perimeter of the rotor. Bearing units are installed in a cylindrical body with a flange and in the cover of the cylindrical housing of the rotor shaft. Three flat square coils, located in the middle part around the four sides of the tubular square housings of micro-linear magnetoelectric generators.

EFFECT: casings of flat square coils are made of permalloy in order to protect them against the mutual influence of external magnetic fields.
