    摘要: 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.

    摘要: A miniature PMDC motor has a wound rotor 15 comprising a rotor core 16 and a commutator 17 mounted on a shaft 14. A cooling fan 20 is directly mounted onto the commutator 17 by use of a mechanical snap-fit type connection. Projections 29 on the commutator mate with recesses in the fan 20 to prevent relative rotational movement and detents including resilient fingers 23 and projection surfaces 34 hold the fan axially.
