A two-pole brush-commutated DC electric motor with a stator and a rotor with a hollow-cylindrical ironless winding having n coil segments and a commutator having n commutator segments. Each coil segment being electrically connected to two adjacent commutator segments. An axis of gravity intersects the rotor axis perpendicularly and passes through the center of gravity of a coil segment or a center line of the coil segment that passes through the center of gravity and the rotor axis spanning a coil plane that defines the angular position of the associated coil segment. Two brush contact surfaces of the commutator segments are electrically connected to this coil segment have a distance bisector intersecting the rotor axis perpendicularly. The distance bisector and the rotor axis span a commutator plane which defines the angular position of the associated commutator segments.
