There is a growing demand for electrical systems that utilise the power of an electric motor. Applications range from motors in: electrical automobiles; household products such as hairdryers; vacuum cleaners; gas compressors; heat-pumps; to flying drones and electric aircraft. All of these applications have a critical dependence on a magnet. There are few options available to motor designers; magnets that are magnetically strong and mechanically weak; or magnets that are magnetically weak with moderate mechanical strength. Our vision is to realise a new magnet architecture which can deliver magnetic products that straddle the current performance divide, producing magnets which have strong magnetic and mechanical performance. To achieve this, LFT will develop new materials processing technologies and consolidation techniques to enable high performance magnets to be consolidated in the solid state.

对利用电动机的功率的电气系统的需求不断增长。应用范围从电动汽车中的电机;家用产品，如吹风机;真空吸尘器;气体压缩机;热泵;到飞行无人机和电动飞机。所有这些应用都对磁体有着关键的依赖性。电机设计人员可选择的磁体很少;磁性强而机械强度弱的磁体;或者磁性弱而机械强度适中的磁体。我们的愿景是实现一种新的磁体架构，可以提供跨越当前性能鸿沟的磁性产品，生产具有强大磁性和机械性能的磁体。为了实现这一目标，LFT将开发新的材料加工技术和固结技术，使高性能磁体能够在固态下固结。
