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 ...
A less common type of dashpot is an eddy current damper, which uses a large magnet inside a tube constructed of a non-magnetic but conducting material (such as aluminium or copper). Like a common viscous damper, the eddy current damper produces a resistive force proportional to velocity. A common use of the eddy current damper is in balance scales.
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 ...
The following is a list of current, former, and confirmed future facilities of Ford Motor Company for manufacturing automobiles and other components. Per regulations, the factory is encoded into each vehicle's VIN as character 11 for North American models, and character 8 for European models.
Allen-Bradley is the brand-name of a line of factory automation equipment owned by Rockwell Automation. The company, with revenues of approximately US $6.4 billion in 2013, manufactures programmable logic controllers ( PLC ), human-machine interfaces, sensors, safety components and systems, software, drives and drive systems, contactors, motor ...
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.
