Summary:An electric motor has a commutator and at least one brush with a concavely curved brush surface as a running surface for the commutator. The brush has two parallel running in ribs, which protrude perpendicularly above the brush surface. The running in ribs each have a radius of curvature which is greater than a radius of curvature of a convex commutator surface. The running in ribs are arranged eccentrically and at a spacing from one another such that they are offset with respect to two opposing surface outer edges of the brush surface. The running in ribs are arranged such that they are inclined at an angle of inclination with respect to the surface outer edges.
