The damper winding (also amortisseur winding[1]) is a squirrel-cage -like winding on the rotor of a typical synchronous electric machine. It is used to dampen the transient oscillations and facilitate the start-up operation.
Generac manufactures gasoline-fueled, diesel-fueled and bi-fuel engine-driven power generation equipment, modular paralleling systems, automatic transfer switches and small engines. [6] The company supplies products to the industrial, commercial, and portable generator markets through many different distributors.
A Stockbridge damper is a tuned mass damper used to suppress wind-induced vibrations on slender structures such as overhead power lines, [1] long cantilevered signs [2] and cable-stayed bridges.
Allen created the Allen key in 1913 and created the Allen Manufacturing Company Inc advertisement for the Allen Safety Set Screw, a brand of set screw, in the Automobile Trade Directory, January 1913. Originally named Allen Manufacturing Company, the business produced hexagonal set screws and wrenches to fasten them.
A schematic of a simple spring–mass–damper system used to demonstrate the tuned mass damper system Tuned mass dampers stabilize against violent motion caused by harmonic vibration. They use a comparatively lightweight component to reduce the vibration of a system so that its worst-case vibrations are less intense. Roughly speaking, practical systems are tuned to either move the main mode ...
Function. The function of a centrifugal pendulum absorber is as with any tuned mass absorbers based on an absorption principle rather than a damping principle. The distinction is significant since dampers reduce the vibration amplitude by converting the vibration energy into heat. Absorbers store the energy and return it to the vibration system ...
Flow-restriction orifice. A gas spring, also known as a gas strut or gas damper, is a type of spring that, unlike a typical mechanical spring that relies on elastic deformation, uses compressed gas contained within an enclosed cylinder. [1] They rely on a sliding piston to pneumatically store potential energy and withstand external force ...
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 ...
