Engineers seeking to significantly improve the efficiency and performance of electric motors could benefit from using Aluminium Matrix Composites (AMCs), according to research from the Innovate UK ‘Make it Lighter with Less’ R&D competition. The project, led by AMC specialist, Alvant, in collaboration with GE Aviation, YASA Motors and the National Composites Centre, achieved a 40% rotor weight saving on an axial flux electric motor while increasing the rotor’s power-to-inertia ratio potential.
