COLLECTOR DC ELECTRIC MACHINE WITH POLE ANCHOR Russian patent published in 2010 - IPC H02K23/00 H02K23/40 H02K23/32 

FIELD: electric engineering.

SUBSTANCE: collector DC electric machine with pole anchor comprises body of magnetic soft material, explicit poles of inductor with coil excitation winding, anchor with explicit poles, collector, mechanism of brush-contact unit, closed drum simple serial (wave) winding of anchor from coils, every of which is arranged on according explicit pole of anchor and comprises one or more turns, and beginnings and ends of coils are connected to each other in a certain manner and are connected to according collector plates of collector, producing closed electric circuit with two parallel branches. At that it is necessary to observe certain ratios between number of explicit inductor poles and number of explicit anchor poles, and also to arrange poles of inductor and poles of anchor with a certain width of pole arc, and collector plates of collector and brushes - with a certain width and a certain number.

EFFECT: provision of high power indices with proper switching and possibility of deep and smooth control of outlet parametres of collector electric DC machine with pole anchor with simultaneous achievement of design simplicity and high reliability, provision of possibility to use this electric machine both at low and high voltages.
