Enameled Aluminum Magnet Wire is used in electromagnets that use electricity to generate a magnetic field.
Magnet wire is a copper or aluminum wire with a thin layer of insulation coating that is wound into coils. These coils are then connected to other components, like transformers and inductors. Magnet wire can also be soldered, which is important for some applications. The enamel coating on the wire protects it from corrosion, and it is also resistant to abrasion and heat.
Compared to uninsulated copper and aluminium wires, enamelled wires have lower electrical resistance. This means that generators using enamel copper winding wires can produce more energy with less power loss. They are also lighter than copper wires, making them ideal for applications where space is limited.When choosing enamelled wires for different applications, it is important to consider the diameter of the copper or aluminium core.
This is defined by the American Wire Gauge (AWG) specification, and it determines the size of the conductor and how much current it can carry. The AWG number can be determined by multiplying the diameter of the wire by 100, then dividing the result by 1000.
The insulation on enamelled wires is typically made from one to three layers of polymer film, which are sometimes composed of two different materials. The resins in these films are designed with specific wire properties in mind, such as abrasion and solderability. They can be formulated to meet certain temperature classes and guarantee service at rated temperatures for thousands of hours.
Magnet wires can be coated with a wide range of epoxy, polyester and polyimide materials, depending on the application and environment. Some of the most common resins are polyvinyl formal or Formvar, polyurethane, polyester and polyester-imide. These coatings are designed with the ability to withstand high temperatures and resist abrasion, chemicals, radiation and moisture.
In addition to providing an excellent dielectric and mechanical strength, these coatings can be made with low viscosity and a low melt point. This makes them suitable for use in a variety of applications, including relays, micro-motors, small transformers, ignition coils, water stop valves and magnetic heads. Solderable polyesterimide coatings, such as the Voltatex 7200 series offered by Axalta, are especially useful in connecting coils of insulated magnet wires to each other and to the magnetic head of the motor.Whether you are building a small electric motor or creating an electric generator, it is important to choose the right magnet wire for your project.
Using the wrong type of wire can cause damage and even a fire. It is essential to read the manufacturer’s instructions for each product you use. In addition, it is important to store the wires properly and protect them from moisture. The best way to do this is to store them in a dry area and ensure that they are not touching each other or any other articles. Finally, always keep the wires away from direct sunlight. By following these simple tips, you can ensure that your project is a success and that the wires are safe and secure.
