Damper winding. Bars and rings of the damper (amortisseur) winding of an AC generator (General Electric, early 20th century). Note the gaps in the cage along the quadrature axes. The damper winding (also amortisseur winding[1]) is a squirrel-cage -like winding on the rotor of a typical synchronous electric machine.
Harmonic balancer lower pulley on a four-cylinder engine. A harmonic damper is a device fitted to the free (accessory drive) end of the crankshaft of an internal combustion engine to counter torsional and resonance vibrations from the crankshaft. This device must be an interference fit to the crankshaft in order to operate in an effective manner.
A dashpot, also known as a damper[citation needed], is a mechanical device that resists motion via viscous friction. [1] The resulting force is proportional to the velocity, but acts in the opposite direction, [2] slowing the motion and absorbing energy. It is commonly used in conjunction with a spring. The process and instrumentation diagram ...
By 1969, the parent company was known as Easco Corporation. [1] Tools made by MDF for Sears have a "V" maker's mark on them, those by Danaher had a "V^" (V and upside down V, sometimes a right-side up V). Variations of the "VV" exist including three digit codes on tools such as ratchets. It is believed that these denote the time frame of ...

Damper (flow) Opposed blade dampers in a mixing duct. A damper is a valve or plate that stops or regulates the flow of air inside a duct, chimney, VAV box, air handler, or other air-handling equipment. A damper may be used to cut off central air conditioning (heating or cooling) to an unused room, or to regulate it for room-by-room temperature ...
In electrical power engineering, fault ride through (FRT), sometimes under-voltage ride through (UVRT), or low voltage ride through (LVRT), [1] is the capability of electric generators to stay connected in short periods of lower electric network voltage (cf. voltage sag). It is needed at distribution level (wind parks, PV systems, distributed ...
