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). The hub (41) is configured with an inner wall section that has contact sections (46) and relieft sections (47), wherein the contact sections are closer to the central axis of the hub than the 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 the commutator to adapt to the shaft and provide room for material that is displaced from the contact sections. The hub (41) and, to a limited extent, the metallic conductive elements (33), absord any stresses and deformation from press-fitting the hub onto the motor shaft without transmitting undue stress and deformation to the interface betweenthe conductive elements and the carbon communtating segments (31).

摘要： Commutator (10) for electrodynamic machines such as electric motors having a cylindrical shell (20) of insulated commutators bars (14). Each of the bar has an outer layer (22) with tangs (18) extending from the outer layer (22) and an inner layer (24) with anchoring tabs (26) extending therefrom. The commutating bars are typically produced from two strips (32, 34) of copper or other conductive metal. The inner layer may be formed of a thinner but stronger material, even of a non-conductive material, but normally preferable to use two strips of copper to facilitate fusion of the materials together. The first strip, which is typically thicker than the second, is formed by punching so that partially formed tangs extend laterally from the side of the strip. The second strip is formed in a similar process to provide anchoring tabs extending from the sides of the second strip. This commutator can be produced economically and efficiently and can be adapted to a wide variety of applications and requirements.
