  2. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    U.S. NRC image of a modern steam turbine generator (STG). In electricity generation, a generator [1] is a device that converts motion-based power (potential and kinetic energy) or fuel-based power (chemical energy) into electric power for use in an external circuit.

    en.wikipedia.org/wiki/Microsoft_Copilot

    On March 16, 2023, Microsoft announced Microsoft 365 Copilot, designed for Microsoft 365 applications and services. [ 43 ] [ 44 ] [ 45 ] Its primary marketing focus is as an added feature to Microsoft 365, with an emphasis on the enhancement of business productivity.

  4. 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 ...

  5. Electronic speed control - Wikipedia

    en.wikipedia.org/wiki/Electronic_speed_control

    Some electric cars with DC motors also have this feature, using an electrical switch to reverse the direction of the motor, but others run the motor in the same direction all the time and use a traditional manual or automatic transmission to reverse direction (usually this is easier, since the vehicle used for the conversion already has the ...

  6. Motor controller - Wikipedia

    en.wikipedia.org/wiki/Motor_controller

    A motor controller is a device or group of devices that can coordinate in a predetermined manner the performance of an electric motor. [1] A motor controller might include a manual or automatic means for starting and stopping the motor, selecting forward or reverse rotation, selecting and regulating the speed, regulating or limiting the torque, and protecting against overloads and electrical ...

  7. Commutator (electric) - Wikipedia

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

    A commutator is a rotary electrical switch in certain types of electric motors and electrical generators that periodically reverses the current direction between the rotor and the external circuit. It consists of a cylinder composed of multiple metal contact segments on the rotating armature of the machine.

  8. Thermoelectric effect - Wikipedia

    en.wikipedia.org/wiki/Thermoelectric_effect

    At the atomic scale, a temperature gradient causes charge carriers in the material to diffuse from the hot side to the cold side. This is due to charge carrier particles having higher mean velocities (and thus kinetic energy) at higher temperatures, leading them to migrate on average towards the colder side, in the process carrying heat across the material.
