摘要： A plane commutator includes a plurality of commutator segments made of carbon compound, a resinous boss member and a plurality of metal base plates. The plurality of the commutator segments forms a disk-like commutator surface at an end thereof and a base portion at the other end. The resinous base member is disposed in contact with the base portion to support the plurality of commutator segments. Each commutator segment has a projection extending from the base portion, and each base plate has an expansible through hole fitted to the projection. Each projection includes metal powder at portion in contact with the through hole to provide good electrical connection.

摘要： A wet-running direct-current motor for a fuel pump having a commutator (2) formed from carbon lamellas (5), and carbon brushes (3) having brush running faces (6) which are fluted in the direction of rotation. The fluting is obtained by curved, parallel ribs of triangular cross-sections whose apexes define the brush running face. The curved ribs have radii offset from the curvature of the commutator surface, the offset being achieved by offset of the center of the radius of each rib in a direction counter to the direction of relative rotation of the commutator and brushes. The motor is rendered usable for fuel pumps of diesel engines.

摘要： Carbon commutator segments are secured to a base member by means of integral anchor pieces disposed within axially extending, cruciform-section slots formed in the outer cylindrical surface of an insulating base member. Elongate contact members having lateral edges seated in lateral parts of the slots are embedded in the anchor pieces and are each provided, at one end, with a terminal for connection to an armature winding lead wire. The carbon segments and the integral anchor pieces are formed by enclosing the base member, together with assembled contact members, in a mould and then injecting a mouldable mixture of carbon powder and carrier material into space between the mould and the assembly. When the injection moulded layer has solidified, an annular-section outer portion of this injection moulded layer is divided into segments by means of axially-extending radial cuts. Holes, formed in a central part of each contact member, facilitate the flow of mouldable mixture and ensure that the mouldable mixture fills that part of each slot which is not occupied by the contact member disposed within slot.

摘要： A commutator assembly for a dynamoelectric machine with metallic brushes has a plurality of composite carbon commutator bars retained on a generally cylindrical molded core with radial extensions and retaining lips at each axial end. A hook member for each bar has a U-shaped portion clamping one end of the bar and trapped in the molded core for retention of the bar against migration due to tangential brush force and a hook portion projecting outward for armature wire connection.

摘要： An electrical machine with a brush commutator arrangement (1) is proposed. Brushes (3) and a commutator (5) are adapted and arranged such that, upon operating the electrical machine (1), the brush (3) and the commutator (5) are displaced relative to each other in a lateral displacement direction (7) and a contact surface (9) of the brush (3) mechanically contacts a contact surface (11) of the commutator (5) along an overlapping area (13) thereby generating an electrical contact. Accordingly, an electric current is transmitted between brush (3) and commutator (5) through the overlapping area (13). An orthogonal electrical conductivity of the brush (3) and/or the commutator (5) in a direction (25) orthogonal to a respective contact surface (9, 11) locally varies along the lateral displacement direction (7). An orthogonal electrical conductivity distribution in the brush (3) and/or the commutator (5) is adapted such that, even when operating the electrical machine at maximum allowable power, for at least 90% of all spatial configurations during displacing the brush (3) and the commutator (5) relative to each other, an electrical current density through the overlapping area (13) does not exceed 130% of a rated maximal average electrical current density through the brush commutator arrangement (1). Due to the specific variation of orthogonal electrical conductivity within the brush (3) or commutator (5), sparking and resulting wear in the proposed brush commutator arrangement (1) may be reduced.

摘要： The invention relates to a commutator, comprising an insulating base and a plurality of commutator segments arranged on the insulating base, wherein each commutator segment comprises a metal layer, a transition layer and a graphite layer arranged on the base in sequence. The transition layer contains a material identical to that of the graphite layer and a material identical to that of the metal layer. The invention further relates to a motor comprising the commutator and a method for manufacturing the commutator. As the transition layer contains the material identical to that of the graphite layer and the metal layer, the problem that the graphite layer and the metal layer are cracked during high temperature sintering is resolved. The service life of the commutator is prolonged. The method for manufacturing the commutator reduces chemical contamination and production cost caused by electroplating and brazing used in a traditional technology.
