  2. Brush (electric) - Wikipedia

    en.wikipedia.org/wiki/Brush_(electric)

    A pair of carbon brushes. A brush or carbon brush is an electrical contact, often made from specially prepared carbon, which conducts current between stationary and rotating parts (the latter most commonly being a rotating shaft) of an electrical machine. [1] Typical applications include electric motors, alternators and electric generators. The ...

  3. Brushed DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushed_DC_electric_motor

    A brushed DC electric motor is an internally commutated electric motor designed to be run from a direct current power source and utilizing an electric brush for contact. Brushed motors were the first commercially important application of electric power to driving mechanical energy, and DC distribution systems were used for more than 100 years ...

  4. Electrical contact - Wikipedia

    en.wikipedia.org/wiki/Electrical_contact

    An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. [1] Each contact is a piece of electrically conductive material, typically metal .

  5. Brushless DC electric motor - Wikipedia

    en.wikipedia.org/wiki/Brushless_DC_electric_motor

    The segments are connected to conductor windings on the rotor. Two or more stationary contacts called brushes, made of a soft conductor such as graphite, press against the commutator, making sliding electrical contact with successive segments as the rotor turns. The brushes selectively provide electric current to the windings.

  6. Commutator (electric) - Wikipedia

    en.wikipedia.org/wiki/Commutator_(electric)

    The contact point where a brush touches the commutator is referred to as the commutating plane. To conduct sufficient current to or from the commutator, the brush contact area is not a thin line but instead a rectangular patch across the segments. Typically the brush is wide enough to span 2.5 commutator segments.

  7. Slip ring - Wikipedia

    en.wikipedia.org/wiki/Slip_ring

    Mercury-wetted slip rings, noted for their low resistance and stable connection use a different principle which replaces the sliding brush contact with a pool of liquid metal molecularly bonded to the contacts. [7] During rotation the liquid metal maintains the electrical connection between the stationary and rotating contacts.

  9. Homopolar generator - Wikipedia

    en.wikipedia.org/wiki/Homopolar_generator

    The electrical contacts are usually made through a "brush" or slip ring, which results in large losses at the low voltages generated. Some of these losses can be reduced by using mercury or other easily liquefied metal or alloy (gallium, NaK) as the "brush", to provide essentially uninterrupted electrical contact.
