With the increasing demand for advanced electric vehicles, the shift in magnet wire production towards plastic-based electrical insulation is accelerating. This evolution is primarily driven by the latest electric motor technologies, which require greater power and energy density, operating at voltages as high as 1,000 volts.
To meet these demands, motor windings are now insulated using cutting-edge materials like Polyether Ether Ketone (PEEK). PEEK stands out for its superior insulation performance, remarkable chemical resistance, and ability to operate at temperatures up to 240°C. Unlike traditional enameling techniques, PEEK provides increased flexibility, enabling tighter bending radii and significantly boosting energy density due to its thinner insulation layers.
For over ten years, Frigeco has pioneered the development of specialized extrusion lines for producing PEEK-coated cables, particularly for oil pump applications. This experience has allowed us to fine-tune our expertise in processing this material. Recently, we’ve made significant advances in manufacturing insulated magnet wire using both PEEK and PPSU.
Our technical prowess has yielded impressive results, including precise control over the crystalline structure of the material, achieving minimal insulation thickness while enhancing its adhesion to the conductor. MFL Group now offers complete machinery solutions for insulated magnet wire production with PEEK, covering every stage, from rod breakdown to final extrusion.
Additionally, we are preparing to launch a PEEK testing extrusion line at our Italian site in Spinetoli.
In light of the energy transition, we are also exploring polypropylene insulation for medium-voltage cables, further broadening our expertise and expanding our product range.
With our proven experience and advanced machinery, we are ready to support manufacturers looking to transition from enamel-based cable production or those venturing into the high-performance insulation market.
