The dimensions of a coil former or bobbin define the MLT of a full wound coil. [1] In some cases the coil is not made of a single wire with multiple turns, and a coil former is not always necessary, but may be constructed in a stack of printed circuit layers . [ 2 ]
The principal power limitation on such coils is the thermal softening point of the adhesives which bond the wire to the bobbin, or the bobbin to the spider and coil. Voice coils can be used for applications other than loudspeakers, where time force linearity and long strokes are needed.
In addition the coil former geometry of the T-Top bobbin differs from the coil former dimensions of PAF bobbins making T-Top bobbins slightly taller and more robust internally than PAF bobbins. Early T-Top humbuckers retain the same patent number sticker on the baseplate into the early 1970s.
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 the particular purpose.
Vintage wooden bobbins, cylindrical, empty of wound fiber, dimensions 16 in. high by 9 in. in diameter. Vintage wooden bobbin, unflanged, wound with yarn and attached to a "shuttle" that fits it for use in a floor loom. A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. [1]
Guitar pickup potting is a process whereby the fine wire coils of a guitar pickup are encapsulated in a substance that inhibits movement of the coil. [1] Guitar pickups are generally made from bobbins wrapped in many thousands of turns of fine wire. If the wire is left unpotted it is possible for unwanted microphonics or oscillations to occur ...
Earlier this season, Georgia’s Kirby Smart, for example, ripped the committee for not knowing football like actual football coaches and players when the 13-person committee includes four former ...
The P-90 is a single coil pickup designed by the Gibson Guitar Corporation. [4] [5] These pickups have a large, flat coil with adjustable steel screws as pole pieces, and a pair of flat alnico bar magnets lying under the coil bobbin. The adjustable pole pieces pick up the magnetism from the magnets.
