Abstract

The invention relates to a commutator (1) for an electrical machine, comprising a plurality of juxtaposed laminations (5) which are separated by respective lamella slots (6) for interaction with wiping contacts and a central passage (3) for sliding the commutator (1) onto an armature shaft of an electric motor. The invention is characterized in that the commutator (1) has a front geometry (10) which is designed to form-lock with a displacement and/or alignment device. The invention further relates to a system.
