ELECTROMAGNETIC-REDUCTION SYNCHRONOUS MOTOR Russian patent published in 1996 - IPC

FIELD: slow-speed power motors. SUBSTANCE: electromagnetic-reduction synchronous motor has toothed rotor with tooth number Z_r, toothed stator, and m-phase winding, each phase being divided into two parallel-interconnected semi-phase with diodes inserted in them. Semi-phases of each phase are spaced 180 electrical degrees apart. Stator teeth are uniformly distributed over its circumference, their number Z_s being related to that of rotor Z_r by equation Z_r=Z_s± p, where p=1,2,3 ... is number of pole pairs in stator m-phase distributed winding. Semi-phases of each phase are differentially interconnected; finishing lead of second semi-phase is connected to starting lead of the first semi-phase. Diodes in semi-phases of each phase are cumulatively connected relative to starting leads of these semi-phases; each semi-phase has p cumulatively connected coil groups. EFFECT: improved design. 2 cl, 2 dwg
