Abstract

Disclosed is a commutator arrangement (1) for supplying power to an electric motor, comprising a motor shaft (2) and a commutator (3) which is connected thereto in a rotationally fixed manner and has a plastic core (5) which surrounds at least part of the shaft (2) and encompasses a number of electric contacts (7) for alternately supplying power to the windings (4) of the motor. The plastic core (5) extends beyond the contacts (7) in an axial direction, optionally at a reduced diameter, and is designed as a receiving element for a ring magnet (9').
