  2. Flywheel energy storage - Wikipedia

    en.wikipedia.org/wiki/Flywheel_energy_storage

    A typical system consists of a flywheel supported by rolling-element bearing connected to a motor–generator. The flywheel and sometimes motor–generator may be enclosed in a vacuum chamber to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings.

    Same tone-wheel generator as the B-3 / C-3 but with power amp and speakers built into the console, along with a separate Reverb amplifier and speaker. [15] C: 1939–1942 [16] Almost same as Model A-B but with church style cabinet. [16] CV: 1945–1949 [17] Based on Model C, Hammond Vibrato was added.

    Uses. Custom wheels are one of the most common ways in which automobile enthusiasts customize their vehicles. Competition-oriented enthusiasts typically switch to lighter, stronger, or larger wheels, while appearance-oriented enthusiasts more often choose larger and more visually distinctive wheels. The most-desirable characteristics of custom ...

  5. Electric generator - Wikipedia

    en.wikipedia.org/wiki/Electric_generator

    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. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even ...

  6. Hub dynamo - Wikipedia

    en.wikipedia.org/wiki/Hub_dynamo

    Hub dynamo. A hub dynamo is a small electrical generator built into the front hub of a bicycle wheel that is usually used to power lights. Often the hub "dynamo" is not actually a dynamo, which creates DC, but a low-power magneto that creates AC. Most modern hub dynamos are regulated to 3 watts at 6 volts, although some will drive up to 6 watts ...

  9. Turbo generator - Wikipedia

    en.wikipedia.org/wiki/Turbo_generator

    Turbo generators are used for high shaft rotational speeds, typical of steam and gas turbines. The rotor of a turbo generator is a non-salient pole type usually with two poles. [5] The normal speed of a turbo generator is 1500 or 3000 rpm with four or two poles at 50 Hz (1800 or 3600 rpm with four or two poles at 60 Hz).
