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.
Originally named Allen Manufacturing Company, the business produced hexagonal set screws and wrenches to fasten them. The terms "Allen wrench" (American English) and "Allen key" (British English) [3] are derived from the Allen brand name and refer to the generic product category "hex keys". W.G. Allen [4] filed the first related patent in 1909 ...
Herbert Appleton Wagner. Wagner Electric Corporation was founded by Herbert Appleton Wagner and Ferdinand Schwedtmann (aka Francis Charles Schwedtman) in 1891. The company manufactured electric engines, electric motors and electric starters for early automobiles. They also made electric lights and many other electric-related products.
Coil winding technology. In electrical engineering, coil winding is the manufacture of electromagnetic coils. Coils are used as components of circuits, and to provide the magnetic field of motors, transformers, and generators, and in the manufacture of loudspeakers and microphones. The shape and dimensions of a winding are designed to fulfill ...
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 regenerative shock absorber is a type of shock absorber that converts parasitic intermittent linear motion and vibration into useful energy, such as electricity. Conventional shock absorbers simply dissipate this energy as heat . When used in an electric vehicle or hybrid electric vehicle the electricity generated by the shock absorber can be ...

The active damping tools utilize a compensating force to the vibrating object in the reversed vibrating direction. Normally, piezoelectric devices are the common apparatus for researchers when developing active damping tools. The passive damping tools can be divided into constrained layer damping tools and tuned mass dampers.
