Abstract
A commutator for an electrical machine, in particular for an electric motor for actuating drives in motor vehicles, has a commutator body that supports commutator laminations. To reduce the electromagnetic radiation, emitted into the environment as interfering radiation, that is engendered by spark development in the commutation operation, the commutator body is embodied as a hollow cylinder, and the commutator laminations are disposed on the inner jacket face of the commutator body.
