koilowanie

Koilowanie is a manufacturing process in which a conductive wire, typically copper or aluminum with electrical insulation, is wound around a core to form a coil. Coils produced in this way serve as inductors, transformers, electromagnets and other magnetic components used in power electronics, communications, and electrical machines. The term covers both manual winding and automated production and includes various coil geometries such as toroidal, solenoidal, and pot windings.

The process starts with selecting the conductor and insulation, followed by choosing a suitable core material—ferrite, laminated steel, or air—depending on the intended application. The winding pattern is determined by the required inductance, resistance and leakage characteristics, after which the turns are laid out and secured. Insulation between turns and layers may be applied with tapes, sleeves or varnishes. After winding, many coils undergo impregnation or varnishing to improve mechanical strength and electrical insulation, after which curing is performed. Termination points, taps and connections are added, and the finished coil is tested for electrical parameters such as DC resistance, inductance, insulation resistance and high-potential (hi-pot) strength, as well as for mechanical integrity.

Equipment ranges from manual winding rigs to semi-automatic and fully automatic coil winders. Different coil forms exist, including toroidal, EE, EI and cylindrical windings, each suited to specific devices. Quality control emphasizes insulation integrity, dimensional accuracy, and reproducibility of electrical characteristics, with compliance to relevant standards and safety requirements.

Applications of koilowanie include power transformers and inductors in power supplies, filtering components in electronic circuits, motor and generator windings, relays, chokes, and other devices relying on magnetic coupling.
