Applying grooves to the winding basis supports the layer-accurate position of the wire during the winding process. This behavior is particularly beneficial for the winding processes where a plastic deformation of the wire is unavoidable immediately before the depositing of the wire onto the winding basis.
The greater the number of turns of wire, the stronger the field produced. Conversely, a changing external magnetic flux induces a voltage in a conductor such as a wire, due to Faraday's law of induction. [3] [4] The induced voltage can be increased by winding the wire into a coil because the field lines intersect the circuit multiple times. [3]
Non-inductive bifilar winding Nikola Tesla's flat inductive bifilar coil. A bifilar coil is an electromagnetic coil that contains two closely spaced, parallel windings. In electrical engineering, the word bifilar describes wire which is made of two filaments or strands. It is commonly used to denote special types of winding wire for ...
Litz wire is a particular type of multistrand wire or cable used in ... The result of these winding patterns is to equalize the proportion of the overall length over ...
Coils are typically wound with enamelled copper wire, sometimes termed magnet wire. The winding material must have a low resistance, to reduce the power consumed by the field coil, but more importantly to reduce the waste heat produced by resistive heating. Excess heat in the windings is a common cause of failure.
Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers , inductors , motors , generators, speakers , hard disk head actuators , electromagnets , electric guitar pickups, and other applications that require tight coils of insulated wire.
Magnet wire is solid wire, usually copper, which, to allow closer winding when making electromagnetic coils, is insulated only with varnish, rather than the thicker plastic or other insulation commonly used on electrical wire. It is used for the winding of motors, transformers, inductors, generators, speaker coils, etc.
Ayrton-Perry winding. An Ayrton–Perry winding (named for William Edward Ayrton and John Perry) is a type of bifilar winding pattern used in winding wire on forms to make RF resistors. Its advantage is that the resulting coil of wire has low values of parasitic inductance and parasitic capacitance. [1]
