A DC-excited brushed motor includes a commutation system with a commutator with vanes uniformly distributed in a circumferential direction and at least two brushes which interact with the vanes, to connect the brushes to a DC voltage network via connecting leads. The commutation system is in a metal housing of the motor, and the motor includes an interference suppressor for the commutation system including an interference suppression choke and a capacitor for each connection lead, and the connection leads include an EMC shield between a connection for the respective capacitor and a housing passage through the metal housing of the motor.

A motor may include a housing, a motor assembly accommodated in the housing, and a mold cover having an outer circumferential surface. The outer circumferential surface may be coupled to the housing, which has electrical conductivity. A noise filter is provided in the mold cover. A ground terminal of the noise filter is electrically connected to the outer circumferential surface of the mold cover.
