Abstract: A device for filtering and interference suppression in an electric motor includes at least first powering brush for an armature commutator of the electric motor, a capacitor having one terminal electrically connected to a strip conductor electrically powering the first brush, and another terminal electrically connected to a ground strip conductor connected to the electric ground of the motor. The capacitor is of the filtering and interference suppression device is non-inductive.

Abstract: The invention concerns a device for filtering and interference suppression (62) in an electric motor (34) comprising at least a first powering brush (16) for an armature commutator of the electric motor (34), comprising a capacitor (64) whereof one terminal is electrically connected to a strip conductor (38) electrically powering a first brush (16) powering the armature commutator of the electric motor (34), and the other terminal is electrically connected to a ground-strip conductor (58) connected to the electric ground of the motor (60). The invention is characterised in that the capacitor (72) of the filtering and interference suppression device (62) is non-inductive.
