ELECTRIC GENERATING DEVICE Russian patent published in 2019 - IPC H02K21/14 H02K23/62 H02K29/00 H02K16/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used both at power plants and in autonomous electric generating complexes. Electric generating device comprises a working chamber with enclosing walls and a longitudinal axis of symmetry, cylindrical current-driving multi-pole magnetic rotor arranged along the axis and coaxially with its surrounding stator in the form of a hollow cylindrical basic frame from ferromagnetic material with a current-absorbing winding from insulated wire fixed on it and connected to the consumer. In device stator base frame is equipped with at least one additional hollow cylindrical extension; all extensions are arranged coaxially around it and are connected both to it, and to each other by longitudinal ribs with height H_r, m, to form individual annular channels with width δ_c=H_r, m; these extensions and ribs are also made of ferromagnetic material, the extensions have their own current-receiving windings fixed on them and connected to the consumer from insulated wire. Wires of windings fixed on stator base frame and its extensions, form inside individual annular channels radial clamps with width δ_w, equal to or greater than 0.85δ_c, m.

EFFECT: increased serviceability, service life and lifetime, as well as electric power of electric generating device.
