In the manufacture of motors, single cores are typically used for connecting the coil to the motor junction box. The cores are cut, stripped and assembled in an automated process. In addition to being compatible with resin, the cores must be able to withstand a brief, high thermal load during the production process. For continuous operation of the motor, the cores require a mechanically robust design that is suitable for the temperature class of the motor. Electron-beam crosslinked RADOX® cores meet the mechanical and thermal requirements and are optimally designed for automatic processing.
