The study, titled OCTOPUS (Optimised Components, Test and simulatiOn, toolkits for Powertrains which integrate Ultra high-speed motor Solutions) follows an initial 18-month investigation that delivered a technological breakthrough in electric drive systems for high-performance vehicles.
Building on the UK’s leading electronics research, the resulting electric drive system exceeded the latest permanent magnet motor performance while simultaneously removing the need for both rare-earth magnets and copper windings, delivering a package both cost effective and recyclable at its end of life.
OCTOPUS will take this leading-edge motor, power electronics and packaging transmission design, adding next generation materials, manufacturing processes, simulation and test cycles to deliver a full e-axle powertrain with unique levels of integration and revolutionary performance characteristics suitable for real world application by 2026.
