An electric machine (10), in particular for the adjustment of movable parts in the motor vehicle, includes a stator housing (22) which receives a stator (12) and a rotor (14), the rotor (14) having a rotor shaft (16), on which a commutator (18) is arranged and which can be energized by electric brushes (20), and the stator housing (22) having an axial opening (24), through which the rotor shaft (16) protrudes out of the stator housing (22), an electrically conducting shielding plate (29) being inserted axially between a brush holder plate (55) and a bearing plate (56) for the rotor shaft (16) in order to form a sandwich component (70), the sandwich component (70) extending transversely with respect to the rotor shaft (16) and covering substantially the entire opening (24).
