Triple the power with capcooltech®

Problem: Heat

The winding is the heart of every electric machine and at the same time its greatest source of heat. Without targeted cooling, performance and lifespan drop drastically. Efficient heat dissipation is therefore the key to more compact, higher-performance machines.

Solution: capcooltech®

With our patented hollow conductor cooling capcooltech®, the waste heat is dissipated directly in the copper, exactly where it is generated. This allows us to achieve an unprecedented power density and temperature stability.

Driven by detail

Hollow conductors enable controlled coolant flow without hotspots. Heat conduction in copper is extremely efficient: up to 1,000 times higher than through insulation. This ensures temperature stability even during load changes.

Years of experience: since 2014, we have been bringing series-ready solutions to the market as a pioneer in hollow conductor technology.

Design & Manufacturing

DEF develops electric machines in a wide range of designs, from outer rotors and inner rotors to axial flux motors – for voltages between 12 and 1000 VDC. The platform approach enables precise scaling to meet customer-specific requirements in industry, automotive, aerospace, and other specialized sectors.

We also offer broad expertise in winding technologies: concentrated, distributed, and wave windings, as well as custom solutions, are implemented using state-of-the-art linear, needle, and pin winding machines. Our manufacturing capabilities are further complemented by both wire and pin technologies.

Development & Validation

Even in the concept phase, real measurement series on prototype coils and stators are used to verify thermal boundary conditions. This data flows directly into FEM-based simulations, enabling rapid feedback loops between digital design, prototyping, and testing. Functional prototypes are quickly realized in DEF’s in-house workshop. On modern test benches, both individual components and complete machines – including cooling systems – are tested under real operating conditions. This creates a development process that reliably ensures both performance and series readiness.
