ABSTRACT:
A direct current electric motor, especially one for driving a fan or blower in a motor vehicle ventilating system, has a motor shaft, a bearing ring around the free end of the motor shaft, and a casing which includes an end plate carrying a bearing element formed with a cylindrical internal face, which defines a housing in which the bearing ring is received. The fixed bearing element has a base portion and a free edge at the opposite axial end of the bearing element from the base. The bearing is formed with reliefs adjacent to the free edge of its fixed element. These reliefs project radially towards the axis from the internal face of the bearing.
