Ampere electric motor targets record power density

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.

In a statement, Ian Foley, managing director of Equipmake said: “This exciting project has the potential to totally change our concept of what an electric motor can offer, and with such a huge amount of performance in a such a small package at as low a cost as possible, this motor is set to further revolutionise e-mobility, whether that’s in automotive or aerospace. We are grateful to Innovate UK for their support and are looking forward to getting the very first Ampere prototypes up and running very soon.”
