Evonik has announced the opening of its PEEK Rectangular Magnet Wire Lab. Built to serve the needs of major Chinese and Asian markets, the lab will focus on research and innovation for polyether ether ketone (PEEK) powder-based applications for electric motors – especially for new-energy vehicles (NEVs) such as hybrid electric or fully electric-drive vehicles.
“The NEV industry chain in China and across Asia-Pacific is rapidly moving upmarket and globalizing, raising the bar for performance limits and delivery speed of critical materials,” said Jinhong Zhang, vice president and general manager of the high-performance polymers business line in Evonik’s Asia-Pacific region. “This lab will support our work with partners to advance the large-scale adoption of Vestakeep PEEK solutions in electric-drive systems, magnet wires and equipment. The aim is to further develop our range of Vestakeep PEEK solutions to withstand even higher temperatures, higher voltages and more demanding operating conditions, and, as such, provide strong support for improved efficiency and enhanced reliability of NEV electric-drive systems.”
The Evonik PEEK Rectangular Magnet Wire Lab will focus on key technical challenges in magnet wire applications, including processing-parameter optimization, coating-structure design, improved adhesion performance and control of dimensions and concentricity.
In collaboration with third-party organizations, the lab will carry out reliability tests on key electrical properties such as breakdown voltage (BDV), partial discharge inception voltage (PDIV), corona resistance and oil-aging resistance, providing material assurance for safe, long-term operation of NEV electric-drive systems. The lab will also be used for sample preparation, validation of new PEEK formulations, and benchmarking against standard products, helping customers accelerate new product development and qualification.
As NEV drive systems evolve toward higher power density, higher efficiency and greater reliability, magnet wires used in motors face increasingly stringent demands regarding heat resistance, electrical performance and the long-term stability of insulation materials.
“By establishing this magnet wire application laboratory, Evonik hopes to work more closely with customers and value-chain partners,” added Felix Teng, director of innovation management for the high-performance polymers business line in Evonik’s Asia-Pacific region. “Our aim is to translate the material performance advantages that Vestakeep PEEK has in motor magnet wire applications into full-system solutions that can be verified through testing and scaled up for mass production.”
