SYNCHRONOUS GENERATOR WITH THREE-LOOP MAGNETIC SYSTEM Russian patent published in 2020 - IPC H02K21/12 H02K16/00 H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electric engineering, namely to low-speed electric generators, and can be used in wind-driven power plants. Synchronous generator with a three-circuit magnetic system includes a rotor made in the form of a ring divided into external, intermediate and internal rotors. On inner side of outer rotor there are ferromagnetic plates connected at ends with rectangular magnetic poles. In the intermediate rotor in the middle permanent magnets are installed in cavities. On inner side of inner rotor there are also fixed ferromagnetic plates connected at ends with rectangular magnetic poles. Permanent magnets of external and internal rotors with identical polarity are installed on ferromagnetic plates in radial direction along circles. Between external and intermediate, and also intermediate and internal rotors there are stator windings interconnected.

EFFECT: improved weight and size characteristics.
