Fluoropolymer Breakthroughs in EV Motor Wire Insulation
The growth of the EV industry is transforming powertrain design. To meet rising expectations for higher power density, faster charging and greater efficiency, EV manufacturers are pushing motor systems from today’s 400-volt architectures toward 800 volts and beyond. While this evolution enables significant performance gains, it also introduces new engineering challenges.
One of the most critical issues lies in the insulation of magnet wire within the motor stator. As voltage and thermal loads increase, traditional insulation systems often fail to provide sufficient reliability, leading to risks such as partial discharge, thermal degradation and chemical breakdown.
