Ultra-kompakte Filterdrosseln unterstützen alternative Antriebskonzepte
Mit 48 V in die Zukunft
Die CO2 Grenzwerte der Europäischen Kommission stellen eine Herausforderung für die Automobilindustrie dar, die mit konventionellen Verbrennungsmotoren nicht zu erreichen ist. Für die Zielerreichung ist eine schnelle und kosteneffiziente Hybridisierung erforderlich. Hierzu sind auch neue elektrische Komponenten wie Inverter und DC-DC-Wandler nötig. Eine der großen Herausforderungen im Inverter ist der stark begrenzte Bauraum, wofür die sehr kompakten Filterdrosseln die optimale Lösung sind.

New cobalt-iron material for motor applications
The golden center
High power combined with low weight is a central requirement for electrical high-performance drives. In aviation or motor sports, laminations made of cobalt-iron alloys from VACUUMSCHMELZE (VAC) are frequently used for this purpose, as typically 20-30 % higher power densities can be achieved compared to electrical steel. For long the technology transfer to premium vehicles or high-performance industrial applications has not made sense due to economic reasons. With the new CoFe alloy VACOFLUX® X1, VAC has now succeeded in closing the existing gap between electrical steel and materials with a high cobalt content. This enables engineers to adapt this technology for a broad range of applications.

Eco-friendly refrigeration technology  
Magnetocaloric cooling ready for series production
The refrigeration and air conditioning industry suffers from the gradual phasing out of the use of hydrofluorocarbons. Magnetocaloric cooling offers an energy-efficient, future-proof alternative without any greenhouse gases. The magnetocaloric material CALORIVAC® developed by VACUUMSCHMELZE (VAC) is now ready for series production and available on a large scale.

Highly linear current monitoring
High precision current transformers
Modern materials and innovative engineering characterize the current transformer standard series of the VACUUMSCHMELZE (VAC). For precise current monitoring in industrial production lines, server farms or substations, this series has been upgraded with a 100 A type which features ultra-linear behaviour and extremely low phase errors. It represents an attractive solution to meet the increasing demands for network monitoring and is therefore the key to reliable and uninterrupted operation.

Innovative manufacturing process for common mode chokes
Smart-Coil - High attenuation at low cost
Hanau - The number of electric cars on the roads is steadily increasing worldwide. The resulting further development of the charging infrastructure leads to considerable network disturbances (EMC), which require complex EMC filters. For this purpose, VACUUMSCHMELZE’s patent-pending smart coils are used, which enable significantly higher attenuation, especially at high frequencies.
