An orthocyclic winding design for a round coil with 150 windings, a wire diameter of 0.3 mm and a maximum winding width of 9 mm shall be calculated. The winding diameter at the winding base measures 8 mm. Structure of a coil with an even number of turns per. Given: Wire-Ø Cu 0,3 mm → CU1L=0,334 mm (According to the table)
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.
A coil with a core which is a straight bar or other non-loop shape is called an open-core coil. This has lower magnetic field and inductance than a closed core, but is often used to prevent magnetic saturation of the core. A coil without a ferromagnetic core is called an air-core coil. [14]
Mean Length Turn, sometimes Mean Length per Turn is the mean length of winding turn in a coil, usually referred to by the initials MLT.The dimensions of a coil former or bobbin define the MLT of a full wound coil. [1]
A helical armature is a form of air-gap electric motor or generator armature wound in a helical fashion as opposed to a conventional random or orthocyclic winding. Such a design is of interest in superconducting motor and generation technology, [1] though comparatively little research has been done on the subject.
When used in a switching transformer, one winding of the bifilar coil is used as a means of removing the energy stored in the stray magnetic flux which fails to link the primary coil to the secondary coil of the transformer. Because of their proximity, the wires of the bifilar coil both "see" the same stray magnetic flux.
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.
A motor can be built upon any flat structure, such as a PCB, by adding coils and a bearing. The coil winding process and the process of joining the coil and core may be simpler. Since the coils are flat, rectangular copper strips can more easily be used, simplifying high-current windings. It is often possible to make the rotor significantly ...
