UNIPOLAR ELECTRIC MACHINE Russian patent published in 1995 - IPC

FIELD: electric machine engineering. SUBSTANCE: active working part of stator incorporates two identical ferromagnetic ring magnetic circuits 6 arranged on side boards on both sides of rotor, ferromagnetic symmetric rows of sector elements 18 of working winding in the form of laminated parts of round ring insulated from each other, connected in series and divided between upper and lower parts of winding with neutral sector gaps with proper insulation. Rotor of machine is formed by radially distributed salient magnetic cores 9 with excitation coils 7, sector contact ring 11 on shaft 2 with brushes 14 placed in excitation circuit as means of current collector and commutation. Positive and negative brushes 14 of excitation buses have constant electric coupling in turns with starts and finished of all pairs of excitation coils through sectors of contact ring 11. EFFECT: increased level of output voltage. 3 dwg
