摘要：Face commutators (30) with substantially planar commutating segments (31)that are bonded to a conductive member (33) which is attached to an insulating hub (41).The hub (41) has an axial bore (43) designed to be press-fitted on the armature shaft (23)of a motor with an inner wall section (43) that is deformed by the motor shaft (23). Thehub (41) is configured with an inner wall section that has contact sections (46) and relieftsections (47), wherein the contact sections are closer to the central axis of the hub thanthe radius of the shaft and which are deformed when the hub is pressed on the shaft.While the relief sections (47), which do not come in contact with the shaft, allow thecommutator to adapt to the shaft and provide room for material that is displaced fromthe contact sections. The hub (41) and, to a limited extent, the metallic conductiveelements (33), absord any stresses and deformation from press-fitting the hub onto themotor shaft without transmitting undue stress and deformation to the interfacebetweenthe conductive elements and the carbon communtating segments (31).
