From simple wire winding to high-tech component
Coils - often hidden inconspicuously inside systems - are at the heart of many drive systems. They convert electrical energy into magnetic fields - and vice versa. But behind this simple description lies a fascinating variety of designs, materials and applications that go far beyond the simple wire winding.
The basics: What is a coil?
At its core, a coil consists of an electrical conductor that is wound into a spiral. When an electric current flows through this conductor, a magnetic field is created. The strength of this field depends on various factors such as the number of windings, the diameter of the coil and the material used.
Coils - much more than just wire windings
The development of drive technology has turned the coil into a highly sophisticated component. Modern coils are no longer just simple wire windings, but often complex systems that consist of different materials and have to be manufactured with precision.
- Core materials: To optimise the magnetic properties of a coil, so-called magnetic cores are often used. These consist of materials such as iron, ferrite or special alloys.
- Insulation: The individual windings of a coil must be insulated from each other to prevent short circuits. Various insulating materials such as lacquer or special plastics are used for this purpose.
- Cooling: At high currents or frequencies, a coil can heat up considerably. To prevent overheating, cooling measures are often necessary, for example using fans or heat sinks.
Coil applications
Coils are used in a wide range of electrical devices and systems:
- Electric motors: In electric motors, coils generate the magnetic field that provides the rotary motion.
- Transformers: Transformers use coils to increase or decrease electrical voltage.
- Inductors: Coils are used as inductors in electronic circuits to limit or delay the flow of current.
- Sensors: Coils can be used in sensors, for example to detect magnetic fields or metallic objects.
