Abstract

The present invention relates to an electrical drive unit with an electric motor and a transmission, wherein the motor has a rotor shaft (6), to which a rotor (10) and a commutator (11) are fitted in a manner fixed against rotation, wherein a commutator sliding contact (23) is provided in order to make contact with the commutator (11), and wherein an electrical connection is provided between an electrical terminal (18) and the commutator sliding contact (23). According to the invention, one cable and one special step in the manufacturing process are dispensed with by virtue of the fact that the electrical connection runs via the rotor shaft (6).
