A damper winding is a squirrel-cage-like winding on the rotor of a synchronous electric machine that dampens oscillations and facilitates start-up. Learn about its history, construction, and applications from various sources.
A harmonic damper is a device fitted to the crankshaft of an internal combustion engine to counter torsional and resonance vibrations. It is essential for engines with long crankshafts or uneven firing order, and it may also serve as a pulley for the accessory drive belts.
A shock absorber or damper is a mechanical or hydraulic device that converts the kinetic energy of a shock into heat and dissipates it. Learn about the history, construction, and types of shock absorbers used in vehicles and other applications.
Van de Graaff generator diagram. A simple Van de Graaff generator consists of a belt of rubber (or a similar flexible dielectric material) moving over two rollers of differing material, one of which is surrounded by a hollow metal sphere. A comb-shaped metal electrode with sharp points (2 and 7 in the diagram), is positioned near each roller ...
A hex key is a tool for turning hexagonal screws, also known as Allen screws or Allen wrenches. Learn about the origin, design and variations of hex keys, as well as their applications and differences from other screw drives.
A turbo generator is an electric generator connected to the shaft of a water, steam or gas turbine for the generation of electric power. Learn about the history, construction features and types of turbo generators, and see examples and references.
Allen is a brand of hand tools, especially hex keys, created in 1913 by Allen Manufacturing Company. Learn about its origin, evolution, and end of production, as well as related terms and references.
A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. It can be used in slip ring motors, electrical generators for alternating current (AC) systems and alternators and in packaging machinery, cable reels, and wind turbines.
