The automotive industry is experiencing significant technological advancements in energy efficiency. Innovations such as thermal energy recovery systems and electrically assisted turbochargers use permanent magnet motors and generators to improve vehicle efficiency.

High-performance magnetic materials from Arnold support motor systems that are smaller, lighter and more efficient while operating in high-speed, high-heat environments.

These capabilities enable vehicles to meet stricter efficiency and emissions regulations. Products include L Type Laminated MagnetsRECOMA® samarium cobalt, Arnon silicon steelshaped field magnets and Wraptite carbon fibre sleeving, as well as system integration of these materials.
