FIELD: electricity.
SUBSTANCE: current-collecting device comprises two collectors and composite brushes, parts of which are located on both collectors and are connected to common current-conducting bus via active resistances. M-way wave guide of anchor is connected to collectors, and parts of brushes have width A of contact with collector that meets the following criterion: A ≤ (m - 1)βc + Δ, where m - number of strokes in wave guide of anchor; where βc - collector division; Δ - thickness of insulating gasket of collector.
EFFECT: simplified design and increased reliability of current-collecting device of electric machine by elimination of idle current-conducting tabs of collectors and using mechanically stronger parts of composite bushes.
