摘要： A commutator has a tabular holding portion defining a thickness direction. A plurality of segments are arranged in one end in the thickness direction of the holding portion in a radial pattern. Each of the segments has a slidable contact surface which is perpendicular to the thickness direction. A feeding brush is brought into slidable contact with the slidable contact surface. A tabular short-circuit unit short-circuits the segments to be set to the same electric potential with each other. The short-circuit unit is arranged parallel to the slidable contact surface. Accordingly, it is possible to enlarge a cross-sectional area which is perpendicular to a current passing direction of the coupling portion while suppressing an enlargement of a dimension in the axial direction of the commutator.

摘要： A motor has a plurality of excitation coils, a commutator having a plurality of segments, a plurality of supply brushes and a short-circuit line. Each coil is connected to corresponding ones of the segments. The supply brushes include a plurality of supply brushes each having one of an anode and a cathode. At least one supply brush has the other one of an anode and a cathode. The supply brushes each simultaneously contact different one of the segments. The short-circuit line short-circuits segments that simultaneously contact the supply brushes of the same pole. The supply brushes of the same pole separate from the short-circuited segments at different times.

摘要： A stator of a direct current motor includes six magnetic poles. An armature of the direct current motor includes an armature core having eight slots, a plurality of windings wound around the armature core as concentrated windings, and a commutator having twenty-four segments connected to the windings. The plurality of windings are connected to one another to form a single closed loop. The direct current motor further includes an anode power supply brush and a cathode power supply brush that slidably contact the segments. The aspect ratio, which is the ratio of the diameter of the armature core with respect to the length in the axial direction of the armature core is set to a range of 3.2 through 5.6. This increases the constraint torque/mass ratio of the direct current motor.

摘要： Teeth of a first core sub-part and teeth of a second core sub-part are alternately arranged in a circumferential direction. Each tooth has a tooth main body, which may include two tilted portions at two opposed circumferential ends, respectively, of the tooth main body. Each tilted portion is angled relative to a corresponding direction parallel to the axial direction of the core. Each one of the first and second core sub-parts may have fitting recesses and fitting projections, which are engaged with the fitting projections and the fitting recesses of the other one of the first and second core sub-parts. Each tapered wall surface of each fitting recess is angled relative to a corresponding direction parallel to the axial direction. Similarly, each tapered wall surface of each fitting projection is angled relative to a corresponding direction parallel to the axial direction.

摘要： A motor includes a commutator, which has twenty-four segments. Each of eight short-circuit members is connected to three of the segments. Each short-circuit member extends in an arcuate form in an angular range corresponding to arranging positions of three segments to be connected to the short-circuit member. The eight short-circuit members are laminated to form a multiple-layer structure in the axial direction of the commutator. The short-circuit members form a substantially cylindrical laminated body. The short-circuit members are formed and arranged such that the number of the layers of the laminated body is less than the number of the short-circuit members. As a result, the axial dimension of the laminated body is reduced and the miniaturization of the motor in the axial direction is achieved.

摘要： A commutator connected to armature coils includes circumferentially arranged segments, short-circuit conductors, and a surge absorbing element. The number of the segments is a multiple of the number of the armature coils. The segments include a plurality of pairs of segments. The segments in each pair are adjacent to each other in the circumferential direction. Each segment in each pair is connected to one of the ends of corresponding one of the armature coils. The number of the short-circuit conductors is the same as the number of the armature coils. Each short-circuit conductor short-circuits segments that are at the same potential to each other. Each short-circuit conductor is connected, either directly or via corresponding one of the segments, to the surge absorbing element, so that the surge absorbing element is electrically interposed between the ends of each armature coil.
