Sovereign power for British drones.
Exsabre is building UK-designed, UK-built brushless motors for military and commercial uncrewed air systems — so Britain no longer depends on China for the component that makes a drone fly.
A critical flight component, sourced from a strategic competitor.
Every drone runs on a brushless motor. Almost all of them are made in China. For the platforms scaling Britain's drone fleet, that's a critical flight component sourced from a strategic competitor — with no domestic fallback if supply is cut. Exsabre exists to close that gap.
UK-manufactured brushless motors, built on a two-tier model.
UK-manufactured motors that build volume and manufacturing maturity.
Traceable, sovereign motors for UAS primes, integrators and the MoD-adjacent market.
Initial focus: 500W–5kW motors for heavy-lift UAS and loitering-munition platforms.
Designed, wound, assembled and tested in the UK.
Designed, wound, assembled and tested in the UK, on a resilient allied supply chain. Exsabre builds on the UK's emerging recycled rare-earth magnet capability to deliver motors that are sovereign, circular and low-carbon — not dependent on any single strategic competitor.
