SYNCHRONOUS GENERATOR PLANT WITH EXCITATION FROM PERMANENT MAGNETS Russian patent published in 2006 - IPC H02K21/12 

FIELD: electric engineering and electro-mechanical industry, in particular, synchronous generator plants with excitation from permanent magnets.

SUBSTANCE: synchronous generator plant has immovable carrying stator assembly with supporting bearings, on which ring-shaped magnetic duct is assembled with polar projections along periphery provided with electric coils positioned thereon with anchor winding of stator, and also ring-shaped rotor mounted on supporting shaft with possible rotation in aforementioned supporting bearings around immovable stator carrying assembly, with permanent excitation magnets mounted on inner side wall. Generator plant also has alternating current rectifier block, connected to anchor winding of ring-shaped stator magnetic duct. Carrying assembly of stator is made of two similar sections, each one of which has ring-shaped bushing with external abutment flange, and ring-shaped rotor is also made of two similar sections, each one of which has ring-shaped sidewall with inner abutment flange. Monolithic magnetic rings of powder-like magnetic-anisotropic material are rigidly mated with inner side cylindrical wall of ring-shaped sidewall of appropriate section belonging to ring-shaped rotor.

EFFECT: higher operational reliability, possibility of adjustment of alternating and direct current voltage as well as of value of alternating and direct current at the output of synchronous generator plant.
