A transducer made of a piezoelectric diaphragm being disturbed by a sound pressure wave. A vibration powered generator is a type of electric generator that converts the kinetic energy from vibration into electrical energy.
Measurements of a typical Tune-o-matic bridge Schaller Wide Travel Tune-o-Matic a.k.a. Harmonica bridge on The Fool. Since its invention, different versions by Gibson have been used: • ABR-1 without retainer wire: 1954–1962 • ABR-1 with retainer wire: 1962–1975 • Schaller Wide travel Tune-o-Matic a.k.a. "Harmonica bridge": 1970-1980 (Kalamazoo plant) • Modern TOM a.k.a. "Nashville ...
One variety, notable for having an adjustable speed, runs continuously with brushes in contact, while another uses repulsion only for high starting torque and in some cases lifts the brushes once the motor is running fast enough. In the latter case, all commutator segments are connected together as well, before the motor attains running speed.
The stoptail bridge consists of two parts: an adjustable fixed bridge piece, such as a Tune-o-matic and a separate stopbar (or stop bar) tailpiece.. A stopbar tailpiece is, as the name implies, a bar-shaped formed metal piece commonly made of pot metal or zinc alloys although aluminum and brass may be used.
Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...
Droop speed control is a control mode used for AC electrical power generators, whereby the power output of a generator reduces as the line frequency increases. It is commonly used as the speed control mode of the governor of a prime mover driving a synchronous generator connected to an electrical grid. It works by controlling the rate of power ...
All of the generating plants at the Morgantown Generating Station were built by the Potomac Electric Power Company, which sold them to the Southern Company in December 2000 as a result of the restructuring of the electricity generating industry in Maryland.
Demonstration hand-cranked magneto made circa 1925, on display at the Musée d'histoire des sciences de la Ville de Genève. 2kW Société de l'Alliance magneto generator for arc lamps, of around 1870. A magneto is an electrical generator that uses permanent magnets to produce periodic pulses of alternating current.
