Enameled wires are widely used in various fields such as electrical and electronic industries. The following are some of the main application scopes:
Various Electric Motors
For example, three-phase asynchronous motors used in industry and single-phase motors used at home. The stator and rotor windings wound with enameled wires are key components for motors to achieve the conversion of electrical energy into mechanical energy.
Generators
Whether it is a small wind turbine generator or a large thermal power or hydropower generator, enameled wires are required to make the windings to realize electromagnetic induction power generation.
Power Transformers
They are used for voltage transformation and electrical energy transmission in the power system. The primary and secondary windings wound with enameled wires can achieve the conversion between different voltage levels.
Electronic Transformers
In electronic devices, such as the high-frequency transformers in switching power supplies, enameled wires are used to make the windings to achieve functions such as voltage transformation and isolation.
Relays
The coils wound with enameled wires are an important part of relays. By energizing to generate a magnetic field, they control the opening and closing of the contacts to achieve the on-off control of the circuit.
Sensors
For some sensors, such as inductive sensors, the coils wound with enameled wires are used as sensitive elements. The change of physical quantities is measured by detecting the change of the inductance of the coils.
Audio Equipment
For example, the voice coils in speakers and headphones are wound with enameled wires. Through the force exerted on the current in the magnetic field, they drive the diaphragm to vibrate and produce sound.
Communication Equipment
Components such as radio frequency coils and filters in communication equipment like mobile phones and base stations often use enameled wires for winding, which are used to realize functions such as signal transmission, reception and filtering.
Electromagnetic Cranes
The electromagnetic coils wound with enameled wires generate a strong magnetic field to lift heavy objects such as steel, realizing the handling and loading/unloading of materials.
Induction Cookers
The internal heating coils are wound with enameled wires. Through the alternating current, an alternating magnetic field is generated, causing eddy currents at the bottom of the cookware to generate heat.
