What is an air core?
An air core refers to a type of magnetic core used in transformers or inductors where the core is made entirely of air or a non-magnetic material. Unlike traditional ferromagnetic cores, which are made of materials like iron or silicon steel, an air core has no magnetic properties. Instead, it relies solely on the magnetic field generated by the current passing through the windings to induce a voltage or current in the secondary winding.
What is an air core?
An air core works by allowing the magnetic field generated by the current in the primary winding to pass freely without being concentrated or guided by a ferromagnetic material. When an alternating current flows through the primary winding, it creates a magnetic field that induces a voltage or current in the secondary winding. Since air has low magnetic permeability, magnetic field lines are not confined or channeled, resulting in minimal energy loss and distortion.
What is an air core?
An example of an air component is an air lug inductor, which consists of coils wound around a non-magnetic former, such as a plastic or ceramic coil. The absence of a ferromagnetic core allows for high quality factor (Q factor) and minimal hysteresis losses, making air lug inductors ideal for applications requiring precise and efficient energy storage and filtering , such as radio frequency (RF) circuits and audio equipment.
The material of an air core is usually air or a non-magnetic material with low magnetic permeability, such as plastic, ceramic, or glass. These materials are chosen for their insulating properties and their ability to support the windings while allowing the magnetic field to pass freely. By using non-magnetic materials, aerial components minimize energy loss and distortion, resulting in high efficiency and performance.
The air core of a transformer refers to the absence of a ferromagnetic core, where the windings are wound around a non-magnetic former or left exposed to the surrounding air. In an air-floated transformer, the primary and secondary windings are usually wound on separate coils or formers, allowing the magnetic field to pass through the air between them. Overhead transformers are commonly used in applications requiring high frequency operation, low energy losses, and minimal distortion, such as radio frequency (RF) and audio transformers.
