Component Specifications

Definition
Coil windings consist of insulated conductive wire, typically copper or aluminum, wound around a core or bobbin to form electromagnetic coils. In receiver coil assemblies, they function as inductive components that convert alternating magnetic fields into electrical currents through electromagnetic induction. The winding pattern, number of turns, wire gauge, and insulation type determine the coil's electrical properties such as inductance, resistance, and quality factor (Q).
Working Principle
Coil windings operate on the principle of electromagnetic induction. When exposed to a changing magnetic field, an electromotive force (EMF) is induced across the coil, generating electrical current. In receiver coil assemblies, this principle enables wireless power transfer or signal reception by converting magnetic energy into usable electrical energy.
Materials
Primary conductor: Copper (Cu) or aluminum (Al) wire with purity ≥99.9%. Insulation: Polyurethane, polyamide, or polyester enamel coating. Core materials: Ferrite, powdered iron, or air core. Bobbin: Thermoplastic (e.g., PBT, nylon) or ceramic.
