[citation needed] The Fuller Wind Turbine System was a bladeless wind turbine announced in 2010 by Solatec LLC. Saphon Energy announced a bladeless wind turbine in 2012. [27] Vortex Bladeless is attempting to produce a wind turbine that isn't actually a turbine. All generators require a magnetic field, a conductor and motion to produce electricity.
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.
In 1998, Generac sold its portable products division to the Beacon group, a private equity firm, who later sold it to Briggs & Stratton Corporation. Upon expiration of a non-compete agreement related to the sale in 2007, Generac re-entered the portable generator market in 2008. [7] In late 2006, Generac was purchased by CCMP Capital of New York ...
A permanent magnet synchronous generator is a generator where the excitation field is provided by a permanent magnet instead of a coil. The term synchronous refers here to the fact that the rotor and magnetic field rotate with the same speed, because the magnetic field is generated through a shaft-mounted permanent magnet mechanism, and current is induced into the stationary armature.
This is useful for large variable speed wind turbines, because wind speed can change suddenly. When a gust of wind hits a wind turbine, the blades try to speed up, but a synchronous generator is locked to the speed of the power grid and cannot speed up. So large forces are developed in the hub, gearbox, and generator as the power grid pushes back.
