ELECTRIC MOTOR TARGETS RECORD POWER DENSITY

摘要

A new electric motor known as Ampere, being developed in the UK, is slated to be the world's most power-dense, delivering 20kW per kg. A collaboration between Equipmake and HiETA, the Innovate UK-backed project will combine advanced additive manufacturing techniques with thermal efficiency. Its metal structure will be 3D printed instead of milled from a single billet, reducing the quantity of high-strength alloys and magnetic material required, while also minimising weight. The companies are aiming for peak power of 220kW at 30,000rpm and a weight of less than 10kg, which would make Ampere around four times more power-dense than conventional electric motors.
