摘要： A commutation assembly mechanically commutates an electric motor. It includes a plurality of distinct electrical contacts forming a circular surface around a motor shaft. At least some of the electrical contacts are electrically coupled to distinct coils within the motor. The assembly further includes a conductive flexible ring and an arm with two rollers. The conductive flexible ring has a circumference that is less than the circumference of the circular surface. In use, the arm is rigidly attached to the motor shaft and has a roller disposed at a distal end for forcing an electrical connection between the flexible ring and specific electrical contacts during rotation of the arm. The electrical connection causes at least one of the distinct coils to be selectively energized.

Next, resin is filled up inside the metallic ring 45 and carbon member 46 to form a resin substrate 48. Next, slits 50 are formed at the metallic ring 45 and the carbon member 46 in the radial direction, so that generally fan-shaped segments 51 insulated from each other and conductive members 52 are formed. Next, a coil is connected to hooks 43 of the conductive members 52 by soldering, welding, etc.

摘要： Commutators for electro-dynamic machines such as electric motors comprise a cylindrical shell of insulated commutators bars, each of which has an outer layer with tangs extending from the outer layer and an inner layer with anchoring tabs extending therefrom. The commutating bars are typically produced from two strips 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 is normally preferable to use two strips of copper to facilitate fusion of the materials together. The first strip, which is typically somewhat 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. These commutators can be produced economically and efficiently and can be adapted to a wide variety of applications and requirements.

摘要： A disc-type commutator is mounted on a rear end surface of an armature of an electrical rotating machine. Plural commutator segments are radially arranged around a rotating shaft, separated from one another by radially extending commutator gaps. A width of the commutator gap is gradually widened along a radial direction of the commutator, so that foreign particles, such as swarfs or brush dusts, entered in the commutator gap are removed by a centrifugal force generated in rotation of the armature. Further, the width of the commutator gap may be gradually widened along its depth direction so that the width becomes wider at its open end that at its closed end.

摘要： An electricity generator is disclosed having electrically conductive, counter-rotating collectors arranged coaxially with a magnetic field extending radially from an axis of rotation. The collectors intersect the radial magnetic field perpendicularly and are electrically connected to each other to conduct current flow in opposite directions to balance the interaction between current flow in the collectors and the magnetic field.

摘要： A planar carbon segment commutator assembly made by forming an annular conductor substrate with an annular front projection extending integrally and axially from a front surface of the substrate. An annular carbon disk is formed on the conductor substrate by overmolding a carbon compound onto the front surface of the conductor substrate and around the annular front projection. The conductor substrate is mounted on an insulating hub. Electrically isolated, circumferentially-spaced commutator segments and corresponding mechanically interlocked conductor sections are formed by making radial cuts through the annular carbon disk and the metal substrate, respectively. According to one embodiment, each of the front projections has a greater cross-sectional area at a distal end than at a base end to mechanically lock the commutator segments onto the conductor sections.
