SYNCHRONOUS GENERATOR WITH EXCITATION FROM PERMANENT MAGNETS Russian patent published in 2015 - IPC H02K21/22 H02K1/27 

FIELD: electricity.

SUBSTANCE: synchronous generator with excitation from permanent magnets comprises a load-bearing unit of the stator with support bearings, where a ring core is formed with pole horns along periphery. The core is equipped with electric coils with multiphase armature wining of the stator, which are placed at pole horns. Circular rotor is mounted at the support shaft so that it may be rotated in support bearings along the stator ring core. Ay inner side wall of the rotor there is a circular magnetic insert with alternate magnet poles out of p-pairs alternating in circumferential direction. The magnet core is made as two identical rings, which may be moved in axial direction. There is a resilient element between the rings.

EFFECT: stabilising output voltage and active power.
