Abstract: An electrical drive, especially for driving a windshield wiper system of a motor vehicle, comprises a worm gear having a worm shaft and a drive motor having a rotor. The rotor and the worm gear are arranged on axial sections of a shaft. The electrical drive furthermore comprises two shaft bearings on which the shaft is received, only one of said shaft bearings being arranged on the shaft in the vicinity of the rotor.

Abstract: The invention describes an electrical machine having an armature with armature slots for accommodating armature coils. At least one armature coil is formed from two coil elements which are arranged symmetrically with respect to one another in relation to an axis of symmetry, which runs through the center-point of the armature shaft. The coil elements are connected to two adjacent commutator laminates of a commutator. A first brush, a second brush and a third brush bear against the commutator in a manner such that they can slide. The second brush interacts with the first brush or the third brush.
