END-MOUNTED COMPOSITE GENERATOR Russian patent published in 1999 - IPC

FIELD: electrical engineering; alternative low-power supplies. SUBSTANCE: generator has case accommodating stator and rotor which are built up of disks placed on common shaft in alternating manner. Disks have certain even number of coils forming sectors with magnetic fields parallel to rotor axis of revolution. Coils are wound on magnetic cores of high flux density with almost rectangular hysteresis loop and connected so that their magnetic poles are alternating in disk plane. Stator disks are rigidly fixed with case and rotor ones are mounted on hollow shaft and rotate relative to stator disks. Coils of stator disks are independent and those of rotor disks are series-connected and brought out to shaft hollow. According to invention, stator end disks are closed on outside with generator magnetic-circuit ground switches made in the form of solid rings of same material as stator and rotor cores; both stator and rotor coils are wound so that magnetic poles in disk planes are alternating. EFFECT: improved generator efficiency. 5 cl, 6 dwg
