The Electric Motor Rewinding Process
Removal or Stripping of the Winding (Coils)
K&N starts by gathering available OEM motor data to take advantage of EASA’s engineering expertise. With data collected, we remove or strip the motor core, then remove the old insulation using precision-controlled calibrated burn-off ovens. Our rewind process ensures the motor core is undamaged and the motor’s efficiency is maintained.
Inserting & Connecting New Winding
Once the electrical motor has been cleared of both insulation and old coils, the new windings are installed. K&N has developed our expertise around inserting and connecting new coils. During and after the installation of new coils, K&N runs comprehensive testing to ensure winding integrity.
Insulating the Complete Winding
After the rewinding process is complete, the insulation process can begin. K&N offers two methods of insulation, dip & bake or VPI. We have the largest Vacuum Pressure Impregnation (VPI) system in the Northwest (click here to learn more about our VPI coil insulation process).
