いぜい１００℃以下である。In recent years, the demand for self-bonding insulated wires has rapidly increased with the labor-saving and rationalization of coil manufacturing processes, and they are now used in large quantities in motors, small motors, transformers, and the like. However, conventional self-bonding insulated wires use polyvinyl butyral resin, phenoxy resin, etc. as the bonding layer. Since lyamide resin or the like is used, the softening temperature is low, and the usage temperature is at most 100°C or less.
又他方機器の小型化、薄型化に伴ってコイルの使用温度
