IMPROVED PERMANENT MAGNET GENERATOR Russian patent published in 2020 - IPC H02K21/20 H02K3/28 H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: electric generator with excitation from permanent magnet comprises fixed stator with output winding, which is installed on teeth, connected in series and according to coils, as well as a rotor equipped with a cylindrical permanent magnet, comprising sets of poles installed from ferromagnetic laminated material, which are installed from its ends and having a through hole in the center. Dielectric gaskets are arranged inside rotor for insulation of plates of set of poles from shaft. Rotor is composite and has a nonmagnetic material shaft at its center. Number of rotor poles is twice less than number of stator teeth. Stator is made from nonmagnetic material and is equipped on its inner part with slots for arrangement of magnetic conductors from ferromagnetic material, each of which is installed in longitudinal plane to rotational axis of the rotor and has two projecting teeth corresponding to sets of poles on the rotor. Output winding coils are installed on magnetic conductors with alternation over sets of teeth at short distance between teeth of one set.

EFFECT: increased efficiency of generator.
