A generator using permanent magnets (PMs) is sometimes called a magneto, or a permanent magnet synchronous generator (PMSG). Armature: The power-producing component of an electrical machine. In a generator, alternator, or dynamo, the armature windings generate the electric current, which provides power to an external circuit.
An early form of an alternating current electrical generator, magneto, built by Pixii Hippolyte Pixii (1808–1835) was an instrument maker from Paris, France. In 1832 he built an early form of alternating current electrical generator, based on the principle of electromagnetic induction discovered by Michael Faraday. [1]
Rotary table (#20) rotates, along with its constituent parts, the kelly and kelly bushing, the drill string and the attached tools and bit. Shale shaker (#2) separates drill cuttings from the drilling fluid before it is pumped back down the wellbore. Stand (#16) is a section of 2 or 3 joints of drill pipe connected and stood upright in the ...
The PT6 consists of two basic sections: a gas generator with accessory gearbox, and a free-power turbine with reduction gearbox. In aircraft, the engine is often mounted "backwards," with the intake at the rear and the exhaust at the front, so that the turbine is directly connected to the propeller.
