Abstract
A system for transferring current between a rotating element and a fixed element, comprising—a support in the general shape of a sheet (10) comprising a conductive portion (11) electrically connected to the fixed element, —a brush holder (20) mounted on the support (10) and supporting a brush (30) that is pushed into contact against the rotating element, —electrical connection means (42) for connecting the conductive portion (11) of the support to a cable (40) that is joined to the brush (30), wherein a resistive element (12) is situated between the brush (30) and the conductive portion (11) of the support (10) and prevents current from flowing directly between the conductive portion and the brush.
