Abstract

The invention concerns a commutator device (1) for electric motor, comprising a housing part (2) and commutator brushes (3) housed in the housing part, each brush comprising a contact surface (8) designed to be pressed in contact against a commutator of the rotor of the electric motor, and a spring part (9) connected to the contact part (7) so as to exert a force on said contact part towards the rotor commutator. The device further comprises a damping element (14) arranged to absorb the vibrations or movements of the contact part of the brushes. The damping element (14) is a thixotropic lubricant.
