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.
Bridgeville, California (population 25) was the first town to be sold on eBay in 2002, and has been up for sale three times since. [ 1 ] In January 2003, Thatch Cay, the last privately held and undeveloped U.S. Virgin Island, was listed for auction by Idealight International. The minimum bid was US$3 million and the sale closed January 16, 2003.

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. The dumbbell -shaped device consists of two masses at the ends of a short length of cable or flexible rod, which is clamped at its middle to the main ...
Shock absorber. Miniature oil-filled Coilover shock components for scale cars. A shock absorber or damper is a mechanical or hydraulic device designed to absorb and damp shock impulses. It does this by converting the kinetic energy of the shock into another form of energy (typically heat) which is then dissipated.
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 ...
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 ...
