Beschreibung
Zusammenfassung:	The invention relates to a current sensor device for monitoring the current flowing through a brush, comprising: -a brush holder (12) extending in a longitudinal direction and defining a through-housing intended to accommodate a brush such that one end of the brush which is intended to brush against a rotating movable surface protrudes from the brush holder, a Hall effect sensor (14) arranged to detect a magnetic field; -a concentrator (16) for concentrating the magnetic fields in a concentrated magnetic field zone and for protecting the zone from external magnetic fields, in which: -the concentrator (16) is mounted on the brush holder (12) so as to surround at least part of the housing of the brush holder; -the Hall effect sensor is mounted on the brush holder (12) at a position located inside the concenrated magnetic field zone.
