SHIELDING ARRANGEMENT FOR A BRUSH-COMMUTATED ELECTRIC MOTOR, AND POSITIONING ELEMENT WITH AN ELECTRIC MOTOR

摘要

The invention relates to a shielding arrangement (20) for a positioning element (1); comprising: - a shielding cap (21) which is made of an electrically conductive material and which has a cylindrical inner part (22) and a retaining section (23) with a diameter that is larger relative to the inner part (22); and - at least one electrically conductive flat closing element (24, 27, 31, 32) for placing onto an end face of the cylindrical inner part (22), said closing element (24, 27, 31, 32) closing only a part of the base of the inner part (22). The invention further relates to an electric motor (2) for an electromotive positioning element (1), comprising: - a shielding arrangement (20) according to one of the preceding claims; - a hollow cylindrical motor housing (5); and - an armature unit (7) which is inserted into the cylindrical motor housing (5) and which supports one or more wound armatures and a commutator (8) on an output shaft (3).
