    摘要： A carbonaceous material is fabricated by a mixture of carbon powder and a binder. 10 % by weight or more and 60 % by weight or less of metal powder to the fabricated carbonaceous material is mixed. The mixed carbonaceous material and metal powder are pressurized and formed. A brush base material is fabricated by burning of the pressurized and formed carbonaceous material and metal powder. The fabricated brush base material is impregnated with oil. An impregnation rate of the oil to the mixed carbonaceous material and metal powder may be 0.5 % by weight or more, for example.

    摘要： A carbon brush is provided that inhibits the temperature increase and the increase of rubbing noise that result from excessive formation of a commutator film.
    A carbon brush includes a carbon block substrate having pores in a surface thereof and an inner portion thereof, the carbon brush making sliding contact with a commutator provided in a motor. A suspension containing an oil and a petroleum-based solvent having a boiling point higher than a temperature of the carbon brush at a time of operation of the motor exists in the pores. It is desirable that the proportion of the suspension be from 0.5 weight % to 6 weight % with respect to the carbon block substrate.

    摘要： A carbon brush is provided that improves motor efficiency and achieves a longer service life. A carbon brush (1) to be pressed against an electrically-conductive rotor (2) is characterized by containing mesocarbon powder and an aggregate material containing carbon as at least one component thereof. It is preferable that the mesocarbon powder have a substantially spherical shape, and it is also preferable that the mesocarbon powder has been subjected to a preheating treatment. In addition, it is preferable that the temperature of the preheating treatment be from 500°C to 700°C.

    摘要： The invention relates to a wire for producing a sliding contact, wherein at least an inner core of the wire comprises a copper/silver alloy. The invention also relates to a sliding contact with at least one such wire, wherein a mating contact is provided, with at least one of the wires resting on the conductive surface of said mating contact, wherein the spring force of the wire on the conductive surface of the mating contact brings about electrical contact between the wire and the mating contact, and the mating contact is moveable towards the wire, with the result that the surface of the wire slides over the mating contact during a movement of the mating contact. Finally, the invention also relates to a potentiometric sensor, a potentiometer, a sliding controller, a position sensor, a rotary switch, an electric motor, a generator, a wind turbine, a slip ring system, a servo drive or a current collector with such a sliding contact.
