Early generator interlock kits consisted of two sliding steel or plastic (depending on the brand) plates held together by three bolts and installed on the front cover of the home's breaker panel, however, some models made by Eaton (formerly Cutler-Hammer) and Siemens for panels manufactured by them install on the adjacent circuit breakers themselves and consist of a sliding arm for breakers ...
Doubly fed induction generator (DFIG), a generating principle widely used in wind turbines. It is based on an induction generator with a multiphase wound rotor and a multiphase slip ring assembly with brushes for access to the rotor windings. It is possible to avoid the multiphase slip ring assembly, but there are problems with efficiency, cost ...
A homopolar generator is a DC electrical generator comprising an electrically conductive disc or cylinder rotating in a plane perpendicular to a uniform static magnetic field. A potential difference is created between the center of the disc and the rim (or ends of the cylinder) with an electrical polarity that depends on the direction of ...
Sketch of a cross-section of slip rings for an electric motor. In this example, the slip rings have a brush-lifting device and a sliding contact bar, allowing the slip-rings to be short-circuited when no longer required. This can be used in starting a slip-ring induction motor, for example.
A grade-school pupil's home do-it-yourself SUT demonstration for a school science fair was constructed and studied in 2012, in a suburban Connecticut setting. [46] [47] With a 7-metre stack and 100 square metre collector, this generated a daily average 6.34 mW, from a computer fan as a turbine. Insolation and wind were the major factors on ...
LING is a 2-dimensional configuration consisting of three parts: the base electrode, the laterally grown piezoelectric nanostructure, and the metal electrode for schottky contact. In most cases, the thickness of the substrate film is thicker than the diameter of the piezoelectric nanostructure. LING is an expansion of the single wire generator ...
a seedling tray like a shed roof on which a mat-type rice nursery is set; a seedling tray shifter that shifts the seedling tray like a typewriter carriage; and; plural pickup forks that pick up a seedling from a mat-type nursery on the seedling tray and put the seedling into the earth, as if the seedling were taken between one's fingers.
Doodlebug tractor is the colloquial American English name for a tractor home-made in the United States during World War II, when production tractors were in short supply. The doodlebug of the 1940s was usually based on a 1920s or 1930s era Ford automobile which was then modified either by the complete removal or alteration of some of the ...
