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.
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 ...
Shock absorbers are an important part of car suspension designed to increase comfort, stability and overall safety. The shock absorber, produced with precision and engineering skills, has many important features. The most common type is a hydraulic shock absorber, which usually includes a piston, a cylinder, and an oil-filled chamber.
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.
Economizer. Economizers (US and Oxford spelling), or economisers (UK), are mechanical devices intended to reduce energy consumption, or to perform useful function such as preheating a fluid. The term economizer is used for other purposes as well. Boiler, power plant, heating, refrigeration, ventilating, and air conditioning (HVAC) may all use ...
A magnetorheological damper or magnetorheological shock absorber is a damper filled with magnetorheological fluid, which is controlled by a magnetic field, usually using an electromagnet. [1][2][3] This allows the damping characteristics of the shock absorber to be continuously controlled by varying the power of the electromagnet.
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 ...
A squirrel-cage rotor is the rotating part of the common squirrel-cage induction motor. It consists of a cylinder of steel laminations, with aluminium or copper conductors embedded in its surface. In operation, the non-rotating stator winding is connected to an alternating current power source; the alternating current in the stator produces a ...
