What is an inductor (coil)?
The inductor is a passive component，it can convert electrical energy into magnetic energy and store it. An inductor is similar in structure to a transformer, but it has only one winding. Inductors have inductances, but they only inhibit the progress of current. If the inductor is in a state where no current flows, it will try to block current from flowing through it when the circuit is turned on. If the inductor is in a state where current is flowing, it will try to maintain the current when the circuit is disconnected. Inductors are also called chokes, reactors, dynamic reactors.
How does inductor (coil) work?
Inductance is the ratio of the magnetic flux of the wire to the current that produces this magnetic flux when an alternating current is passed through the wire. When a direct current flows through the inductor, only fixed magnetic lines of force appear around it, which does not change with time. However, when an alternating current is passed through the coil, the magnetic field lines that change with time will appear around it. The change of the magnetic field line comes from the change of the external alternating power source, so from the objective effect, the inductance coil has the characteristic of preventing the current change in the alternating current circuit. Inductance coils have characteristics similar to inertia in mechanics. They are named “self-induction” in electricity. Usually, sparks will occur at the moment when the knife switch is opened or the knife switch is turned on. This self-inductance phenomenon produces very Caused by high induced potential.
The type of Inductor (coil)?
12 types of inductors as follow:
1. Iron Cored Inductors
The most recognizable magnetic material is iron, making it a great choice for inductors. The following image shows this kinds inductors:
2. Air Cored Inductors
There is a simple winding in this kind of air core inductor,its core material is only air. The following image shows this kinds inductors:
3. Ferrite Cored Inductors
A ferrite is a type of ceramic made by mixing ferrous oxide with small amounts of one or more metallic elements and firing it. The following image shows this kinds inductors:
4. Variable Inductors
Inductor windings form the magnetic core by moving it inside and outside. We can adjust the inductance value using this magnetic core, a variable ferrite core inductor can be formed by moving the core inside and outside the wound coil on a ferrite core inductor. The following image shows this kinds inductors:
5. Laminated Core Inductor
A laminated core inductor is composed of a bobbin, a laminated core, and a coil which surrounds the bobbin. The following image shows this kinds inductors:
6. Bobbin Inductor
A laminated core inductor is composed of a bobbin, a laminated core, and a coil which surrounds the bobbin. The following image shows this kinds inductors:
7. Toroidal Core Inductor
This type of electronic core contains a magnetic field very well because of its closed-loop nature, thereby improving the size and inductance. The following image shows this kinds inductors:
8. Axial Inductors
The inductor is surrounded by green material where the values are printed as colored bands, so we can determine its value by simply reading the color bands and comparing them with the color code chart similar to a resistor. The following image shows this kinds inductors：
9. Wireless Charging coils
Wire rolled up into a ferrite coil can be used to discharge wirelessly. The following image shows this kinds inductors：
10. Thin Film Inductor
This type of inductor is built on a thin strip of ferrite or magnetic material. The copper trace is shaped like a spiral and placed on the substrate. This design is stable and vibration-resistant. The following image shows this kinds inductors：
11. Multi-Layer Inductor
This type of inductor has multiple layers of wire wound on top of each other, therefore it has a large inductance because there is an increase in the number of turns. The following image shows this kinds inductors：
12. Coupled Inductor
Coupled inductors are formed when two wires are wound around a common core. Inductors can be connected in parallel, series or as a transformer in accordance with the application requirements; they transfer energy from one winding to another by mutual inductance; the most common coupling ratio is one-to-one for DC-DC converters. The following image shows this kinds inductors：
