copper magnet wire is a wire whose conductor is copper wire and is mainly used for windings of motors. In addition, enameled wire is also one of our main products. How is enameled wire made? Coat the corresponding paint solution on the conductor, and then volatilize the solvent, solidify and cool the paint film. Enameled wire can be divided into polyester enameled wire, polyesterimide enameled wire, polyamideimide enameled wire, polyimide enameled wire, oil paint, acetal paint, polyurethane enameled wire, etc. according to the insulating paint used. Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, refrigerant resistant enameled wire, etc.
The earliest enameled wire is oily enameled wire, made of tung oil. The paint film has poor abrasion resistance and cannot be directly used to make motor coils and windings. It needs to be covered with cotton yarn when used. Later, polyvinyl formal enameled wire came out, and its mechanical properties were greatly improved. It can be directly used in motor windings and is called high-strength enameled wire.
With the development of weak current technology, there has been a self-adhesive enameled wire, which can obtain a coil with better integrity without dipping and baking. But its mechanical strength is poor, and it can only be used in micro motors and small motors. In addition, in order to avoid the trouble of first removing the paint film during soldering, direct soldering enameled wire has been developed. The paint film can fall off in the high-temperature tin enamel tank to make the copper wire easy to solder.
As the application of enameled wire is becoming more and more extensive, the requirements are becoming stricter, and composite enameled wire has been developed. The inner and outer paint films are composed of different polymer materials, such as polyesterimide/polyamideimide enameled wire.
