The wire is fed through a guiding tube. Before starting the actual winding process, the wire is mounted to a post or a clamping device of the coil body or winding device. By the linear laying movement of the wire guiding tube, the component to be wound is turned in a way that the wire is distributed throughout the winding space of the coil body.
Coil bind is a style of setup used in various levels of NASCAR racing. Coil bind setups utilize very soft front springs and very stiff rear springs to control the pitch attitude of the body. [ 1 ] This is in contrast with conventional setups which place the stiffer springs at the front of the car for superior mechanical grip , that is grip via ...
An ignition coil consists of an iron core surrounded by two coils (windings) made from copper wire.The primary winding has relatively few turns of heavy wire, while the secondary winding consists of thousands of turns of smaller wire and is insulated from the high voltage by enamel on the wires and layers of oiled paper insulation.
The primary winding carries the low voltage battery current, and the secondary winding generates the high voltage for the spark plug. Attached to the end of the coil is an interrupter or trembler, a magnetically operated switch, which repeatedly breaks the primary current to create flux changes in the transformer needed to produce high voltage.
Most ignition systems used in cars are inductive discharge ignition (IDI) systems, which are solely relying on the electric inductance at the coil to produce high-voltage electricity to the spark plugs as the magnetic field collapses when the current to the primary coil winding is disconnected (disruptive discharge).
The coil shell is made with carbon steel that has a combination of good strength and good magnetic properties. Copper (sometimes aluminum) magnet wire, is used to create the coil, which is held in shell either by a bobbin or by some type of epoxy/adhesive. [3] To help increase life in applications, friction material is used between the poles.
The ignition coil is a transformer. The primary winding (called the low-tension winding in early texts) is connected to the battery voltage when the points are closed. Due to the inductance of the coil, the current in this circuit builds gradually. This current creates a magnetic field in the coil, which stores a quantity of energy.
Basket winding (or basket-weave winding or honeycomb winding or scatter winding) is a winding method for electrical wire in a coil. The winding pattern is used for radio-frequency electronic components with many parallel wires, such as inductors and transformers. The winding pattern reduces the amount of wire running in adjacent, parallel turns.
