REACTION STEP MOTOR Russian patent published in 1994 - IPC

FIELD: discrete electric drive. SUBSTANCE: fitted on nonmagnetic plates is magnetic circuit with two pairs of poles 4 of similar angular extent with two pairs of magnets 5 installed in between. Four-toothed rotor disks are installed with turn through tooth division, their extent ratio being 1:2. Magnets 5 and poles 4 of magnetic circuit have angular extent equal to half the extent of spaces between poles 4 of magnetic circuit. Extent of space between edges of poles 4 and magnets is equal to half the extent of poles. Two pairs of magnets 5 have similar polarities of poles pointed to rotor and are installed so that one magnet is arranged between poles 4 of magnetic circuit closed over perimeter. EFFECT: enhanced operation reliability, enlarged operating capabilities. 18 dwg
