Electromagnetic wire

2017/3/25      view:

    Electromagnetic wire, also known as winding wire, often according to the insulation layer of insulation materials and manufacturing methods are divided into enameled wire, wrapped around the wire, enameled wire wrapped around and inorganic insulation wire. The earliest enameled wire is made of tung oil and so on, which can not be directly used in the manufacture of motor windings and windings. Later, the advent of polyvinyl formal enamelled wire, its mechanical performance is greatly improved, can be directly used for motor winding, which is called high strength enameled wire. 

    With the development of the weak current technology, there is a self adhesive enameled wire, which can be used to obtain a better coil without dipping and baking. But the poor mechanical strength, can only use micro motor, small motor. In addition, in order to avoid the trouble of removing the paint film in the first place, the direct welding enamelled wire is developed, and the coating can be detached in the high temperature tin bath to make the copper wire easy to weld. The application of enameled wire is more and more extensive, and the requirement is more and more strict.

    Enameled wire insulating paint according to their use can be divided into polyester enameled wire, polyester imide wire, polyamide imide enamelled wire, polyimide enameled wire, polyamide imide enameled wire, enameled wire and corona resistant, oil paint, acetal paint, polyurethane enamelled wire etc.. Sometimes according to special use classification, such as self-adhesive enameled wire, enameled wire resistance to refrigerants.
