Enhancing Power and Efficiency in E-Motors

As electric motors (e-motors) continue to push the design envelope with higher voltages, higher temperatures and new cooling fluids, polymeric materials used in e-motor manufacturing must be able to maintain electrical and mechanical properties in these more aggressive environments. In addition to maintaining electrical properties, the polymer must be tough enough to support harsh bending operations during manufacturing, provide good abrasion and scratch resistance, and be resistant to the water/glycol-based coolants or ATF used for thermal management.

Syensqo’s specialty polymers for e-motors are equipped with superior features to enhance the power and efficiency of a variety of e-motor applications. Our broad portfolio of e-mobility materials offer advanced insulation properties, which help OEMs meet the demands of reduced motor size and weight paired with increased operating voltage and temperatures.
