Single-phase inductors

In electrical engineering, inductance is a physical magnitude defined as the “coefficient of self-inductance” and it is the ability of an electrical circuit to connect with the flow of the magnetic field generated by the current flowing through it.

In practice, a single-phase inductor (or impedance component or reactor) is an inductive electromagnetic component consisting of a winding (coil or solenoid) made of conductive wire with either an air core or a magnetic metal plate core.  The core may be either a cladded core or a toroidal core.

The main use of these inductive components is as a direct current filter (filter or choke inductance) and as a current limiter in single-phase and three-phase electric circuits (power factor correction capacitor banks, electronic power supply units, rectifiers, electricity distribution systems).

Correct sizing and calculation analysis depends on the type of use. E.F.C. can design and build inductors for various applications.
