Description

Combined inductor

Technical Field

The utility model relates to an inductor preparation technical field specifically is a modular inductor.

Background

An inductor is a component that can convert electrical energy into magnetic energy for storage. The inductor is similar in structure to a transformer, but has only one winding. The inductor has an inductance that only impedes the change in current. If the inductor is in a state where no current is passing, it will try to block the current from flowing through it when the circuit is on; if the inductor is in a current passing state, the inductor will try to keep the current unchanged when the circuit is opened. Inductors are also known as chokes, reactors, dynamic reactors.

The inductance of the inductor depends mainly on the number of turns (number of turns) of the coil, the winding method, and the materials without magnetic core and magnetic core. Generally, the greater the number of turns of the coil and the denser the coil wound, the greater the inductance. When electricity related experimental teaching is carried out, in order to verify the relation between the inductance of the inductor and the number of turns of the coil, the coils with different numbers of turns are used, but due to the limited number of the coils, the obtained experimental data are less.
