A drive device for a hydraulic pump of a braking system for a motor vehicle includes a housing, a rotor, a rotor shaft mounted in the housing and supporting the rotor, and a commutator arranged in the housing. The commutator includes at least one commutator brush held by a brush holder. The commutator brush cooperates with a commutator ring arranged on the rotor shaft in a non-rotatable manner. The brush holder includes a sealing ring assigned to the commutator which is arranged coaxially to the rotor shaft and interacts with the rotor shaft in a sealing manner.
