UNIPOLAR MACHINE Russian patent published in 1995 - IPC

FIELD: electromechanical engineering. SUBSTANCE: running winding of bar type is replaced in machine by fixed winding in the form of rows of symmetrical laminated ferromagnetic sector members installed in interpolar space of inductor forming free gaps within which field coils reverse their polarity so that only south pole is active in top semi-sphere and, vice versa, only north pole is active in bottom semi-sphere. EFFECT: improved operating reliability of machine due to interchanging of movable and fixed parts of machine with provision for fixation of running winding of output voltage and elimination of multiple sliding contacts with brushes and commutator bars from its circuit. 4 dwg
