PEEK, a new alternative to enamel!
High-voltage drivetrains demand higher chemical, thermal, electrical, and mechanical capacities of the magnet wire used in the stator of the e-motor. To meet these new requirements and extend the lifetime of the copper winding wire, we replaced the traditional insulation with an innovative polyetheretherketone or PEEK-coating. The thin coating (100-200µm on average) is applied in one extrusion step using a single layer, which helps you save plenty of time during the production process. Additionally, the extruded coating …
- increases the fill factor which boosts powertrain performance and efficiency
- has higher insulation power (= less corona sensitive)
- doesn’t crack when bent in extreme positions
- allows for a defect-free usage in mission-critical 800V-applications
