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

FIELD: electricity.

SUBSTANCE: proposed collector electric motor with pole anchor comprises body, inductor core with explicit poles assembled from insulated sheets of electrotechnical steel with high magnetic permeability, coil winding of inductor excitation, anchor with explicit poles, collector, mechanism of brush-contact unit with brushes, closed drum simple serial (wave) winding of anchor made of coils, every of which is installed on according explicit pole of anchor and comprises one or several 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, creating closed electric circuit with two parallel branches, besides winding of inductor excitation relative to anchor winding is connected serially. Besides it is necessary to observe certain ratios between number of inductor explicit poles and number of anchor explicit poles, and also to make 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 certain number.

EFFECT: invention provides for high power indices with proper switching and possibility of smooth and deep control of output parametres of collector electric motor with pole anchor with simultaneous achievement of design simplicity and high reliability.
