FIELD: machine building.
SUBSTANCE: group of inventions refers to engineering and can be used in linear electric motors. Flywheel contains a body made of non-magnetic material, inside which a chamber is made containing a magnetic liquid in a colloidal state. Body made of non-magnetic material is rigidly attached to the external structure. Magnets in the form of straight circular cylinders (option 1) or straight circular cylindrical rings (version 2) are placed in the chamber with the possibility of enveloping the magnetic fluid contained in the chamber. Body is a hollow torus of annular cross-section. Rotor is made up of magnets magnetized in the axial direction, and magnetic inserts between the magnets.
EFFECT: decrease in frictional losses is achieved at zero and low rotor speeds.
