enrolamento

Enrolamento is a Portuguese noun that designates the act or result of winding, wrapping, or coiling something around a core, form, or axis. The term is used for items that can be arranged in a spiral or layered manner, and it can refer to both the process and the resulting configuration. Materials commonly involved include wires, cables, threads, fibers, and filaments, as well as components designed to be wound for storage or function.

In electrical engineering and related fields, enrolamento refers specifically to the winding of conductive material around a magnetic core to form a coil. This is a central concept in transformers, motors, and inductors. The primary and secondary windings (enrolamentos) determine voltage transformation, inductance, and magnetic coupling. The quality of an enrolamento—with correct turns, insulation, and impedance distribution—significantly influences performance and safety.

Outside electronics, enrolamento appears in textile manufacturing as winding yarns or fibers onto spools or bobbins, and in cable management as the organization and winding of cables for storage or installation. In everyday language, enrolamento can also describe a tangle or entanglement, metaphorically referring to a complicated situation or mesh of connections.

Etymologically, enrolamento derives from enrolar, meaning to roll up or coil. Related terms include bobina (coil), bobinagem (winding process), and enrolar (to wind up). The concept is widely used across engineering, manufacturing, and common vernacular to convey the notion of a wound or coiled arrangement.
