Hyperdrives specializes in the development and production of electric drive systems that are cooled by hollow conductors. These types of electric drives feature a very high continuous power density and efficiency at really low costs.

• Drive systems cooled by hollow conductors and integrated SiC power electronics
• Continuous power density of >8kW/kg (incl. SiC inverter)
• Maximum efficiency in the partial load range
• Established radial flow design with distributed windings which can be used in all rotor topologies (also without any rare earth magnets, e.g. separately excited rotors)
• Production processes which can be industrialized and integrated into existing production landscapes
• Solely standard automotive materials and components

Lambda Resins GmbH – casting resins for electric motors

Development and production of thermally conductive casting resins for potting electric motors

Potting compound “Lambdapox”:

•  very high thermal conductivity up to over 8 W/m⋅K
•  low viscosity and good impregnation ability from 1,500 mPas
• excellent wetting properties and outstanding adhesion
• no measurable shrinkage during hardening
• high mechanical strength in the working range up to 180°C
• reactivity can be adjusted using chemical accelerators
• thermal class H 180°C
• high thermal resistance at peaks even above 200°C
• extremely low thermal expansion coefficient of 8 - 14 ppm
• no cracking in the thermal shock test from -40 to +180°C
• very high insulation resistance, at 180°C >1.3 G Ohm
• fire behavior according to UL94 V0 (in preparation)

Standard-Metallwerke GmbH (Werl/Germany) - with approx. 450 employees - has been recognised as a reliable partner for precision tubes and fluid line components for more than 100 years. We are established on the market in the automotive industry and other industrial sectors with our semi-finished products, components and rigid busbars. Specialized in the materials aluminium and copper, we also provide products made of steel, stainless steel and composite materials.

Our coating know-how has been perfected over a quarter of a century and allows us to apply various insulation materials to a wide variety of materials by means of extrusion according to customer requirements. In addition to electrical isolation and corresponding mechanical resistance, this also ensures optimum surface protection against aggressive media and abrasion. The special process achieves a strong adhesion of the coating to the conductor material, which enables bending without wrinkling or tearing of the respective coatings with voltage loads of up to 1,000 V.

• Core materials: aluminum, copper, cupal
• Coating materials: PA12, PEEK, PPS, XLPE
• Dimensional range: up to 80 mm x 8 mm
• Coating thickness: 100 – 1200 µm

Based on our experience in coating technology, we are the pioneers in the field of extruded busbars, which are supplied on coils for further processing. However, we can also provide busbars that have already undergone further processing, which includes cutting to fixed length, end stripping and bending, for example.

Whether as a material supplier or manufacturer of complete system components - we are at your side as a reliable partner with our expertise, from development to series delivery!

Our association within the Wilms Group offers decisive advantages.
