What Cooled Motors does
Cooled Motors Ltd is a Nottingham, UK-based private deep-technology company developing advanced thermal and electromagnetic solutions for electric motors. The company addresses the core thermodynamic bottleneck in electric machines — rotor heat buildup — through three proprietary products: CoolShaft™, a water-based rotor cooling system featuring aerospace-grade CFD-optimised flow paths and a proprietary SIL 4 level multi-layer sealing system; CoolDisc™, a complementary water-based stator cooling system that enables the elimination of oil cooling; and UniSync™, a magnetless motor built on the patented UESM (Unified Excitation Synchronous Motor) topology that is positioned as a drop-in replacement for permanent magnet motors compatible with standard 3-phase inverters. The company claims these technologies together deliver up to 70% more continuous power, 50% smaller and lighter motors, and up to 70% cost reduction through rare-earth magnet elimination, with disclosed prototyping work on a BMW i3 retrofit showing a 30% continuous-power increase in the 3000–8000 rpm range and a rotor temperature drop from 130°C to 90°C.
The commercial model is exclusively B2B and enterprise-focused, monetising through technology licensing (royalties on CoolShaft™, CoolDisc™, and UniSync™ IP) and direct component supply to automotive OEMs, Tier 1 suppliers, heavy-duty vehicle manufacturers, defence organisations, and adjacent verticals such as electrified marine, eVTOL/aerial mobility, and wind turbine generators. The go-to-market emphasises direct partnership engagement via a website inquiry form, with no disclosed pricing, no named customers, and a team of 1–10 employees. To date, funding has been non-dilutive: a Transport Research and Innovation Grant (TRIG) from the UK Department for Transport and Connected Places Catapult for heavy-duty truck motor development, equity-free investment from the Royal Academy of Engineering's Enterprise Hub programme, and accelerator placement in MassChallenge. The company is also a finalist in the TBAT Innovation Challenge 2025 and the EU-Startups Summit 2026 Pitch Competition.

Cooled Motors product offering
Product offeringCore offering
Cooled Motors designs and supplies proprietary electric motor cooling components and magnetless motor systems. Its core offerings are CoolShaft (a water-based rotor cooling system), CoolDisc (a water-based stator cooling system), and the UniSync motor (a magnetless Unified Excitation Synchronous Motor). These products are sold or licensed to automotive OEMs, Tier 1 suppliers, heavy-duty vehicle manufacturers, marine, aerospace and defence integrators as drop-in upgrades or replacement motor architectures.
Product overview
Cooled Motors offers a suite of proprietary electric motor technologies centered on advanced cooling solutions. The core product portfolio consists of the UniSync™ motor (a magnetless EESM/UESM motor topology), CoolShaft™ (water-based rotor cooling technology), and CoolDisc™ (advanced stator cooling). These products are designed to work independently or together: CoolShaft™ and CoolDisc™ can be integrated into existing motors for immediate performance gains (50-70% more continuous power, 50% size reduction), while UniSync™ represents a complete magnetless motor that leverages these cooling technologies to eliminate rare-earth magnets without performance compromise. The company targets electric vehicle OEMs, heavy-duty vehicle manufacturers, marine, aerospace, and industrial applications.

Cooled Motors competitors and assessment
Company assessmentBroad incumbents
- Dana Incorporated: Global supplier of thermal management and drivetrain solutions with growing e-Propulsion portfolio including integrated cooling for electric motors, inverters, and batteries. Comparable as an incumbent in electrified powertrain thermal management who could supply motor cooling solutions in-house to OEMs in lieu of licensing from startups.
- YASA (Mercedes-Benz): UK-origin axial-flux motor developer acquired by Mercedes-Benz, now supplying high-performance motors for AMG.EA and other premium EV programmes. Comparable as a once-small UK motor technology firm that scaled by integrating into a major OEM — the most likely strategic outcome scenario for Cooled Motors.
- BorgWarner: Major Tier 1 automotive supplier with HVH high-voltage electric motors and integrated drive modules for commercial vehicles and passenger EVs. Comparable as an incumbent competing for the same OEM thermal management and motor programmes Cooled Motors targets, with much deeper R&D and customer relationships.

- Magnax: Belgian startup developing yokeless axial-flux motors for EVs, aerospace, and marine. Comparable as an emerging European motor technology company pursuing higher power density via novel topology and is targeting the same OEM displacement opportunity as Cooled Motors.
- H3X Technologies: US-based startup building high-power-density integrated motor drives for EVs, aerospace, and defence. Comparable as an emerging player using advanced thermal management and novel winding topologies to achieve high specific power and pursue aerospace/automotive OEM contracts.
Direct peers
- Turntide Technologies: Developer of switched reluctance (magnetless) electric motors and integrated motor controls for EVs, buildings, and industrial applications. Comparable as a peer pursuing permanent-magnet-free motor topologies with proprietary thermal and control integration.
- Equipmake: UK-based electric motor specialist focused on magnetless and high-performance motors for EVs, buses, and aerospace applications. Directly comparable as a small UK-headquartered motor technology company targeting OEM displacement of permanent magnet architectures.
- Saietta Group: UK-listed (AIM) electric motor company developing axial-flux motors for light commercial vehicles, e-motorcycles, and marine propulsion. Comparable as another small UK EV motor technology firm selling/licensing novel motor architectures to automotive and mobility OEMs.
