Rare-earth free magnetless water cooled motors for maximum performance, compactness and reduced costs.
Electric motors have powered industry for nearly two centuries. Today, electrification demands far more from them. Greater power density, higher efficiency, lower cost and a secure, sustainable supply chain.
Most high-performance electric propulsion motors depend on rare-earth permanent magnets. Their supply and processing are heavily concentrated in one country, exposing manufacturers to geopolitical tensions, export restrictions and price volatility. The current global climate has made one thing clear, technologies essential to transport, industry and national security should not depend on resources controlled by a single nation.
Cooled Motors has developed a breakthrough patented magnetless motor topology with a fundamentally new approach to electromagnetic field generation with a systems level approach. The result is UESM, a new class of magnet-free motor topology designed to overcome the industry’s greatest challenges without compromising power, efficiency or cost.
Our goal is rare-earth-free motors, greater independence and a bigger future.
Our vision is a world in which electric propulsion and defence systems no longer rely on rare-earth magnets or fragile, geographically concentrated supply chains.
Our UESM motor topology is built from a suite of proprietary technologies, including our breakthrough patented electromagnetic approach, innovative compact exciter system, advanced control strategy, and high-performance rotor winding. The motor is designed for compatibility with standard three-phase inverters, enabling OEMs to replace permanent-magnet motors without platform changes, specialised power electronics, or costly retooling.
UESM is inherently scalable making the same modular technology stack supports motors from 50 kW continuous to well over 500 kW, all manufacturable on shared production lines. This ensures rapid, cost-effective expansion from prototype to mass production, anywhere in the world.
Our approach emphasises commonised parts, modular design, and manufacturability, allowing global suppliers to adopt the technology with minimal investment. The result is a next-generation motor platform that delivers permanent-magnet performance with a simpler, more scalable, and more sustainable supply chain.
