Air-compressors and electric turbochargers achieve more than 100,000 rpm and in combination with the requirement for low latency, this results in application temperatures of around 200°C. VACOMAX 262 TP provides not only excellent high-temperature properties, in comparison to all currently available SmCo magnets it is also characterized by a much higher energy density, leading to most compact system sizes.

Due to VAC’s unique high yield single part pressing technology, VACOMAX 262 TP is available for the high volume demands of the automotive industry. In many applications, the high rotational speeds lead to mechanical stresses in the rotor. Remedy for these are metal or carbon fiber bandages that protect the brittle material. The assembly of bandaged and balanced rotors is a further competence that distinguishes VAC, as well as the complete in-house capability from material development to rotor assemblies.

„The ability to control the fuel-to-air-ratio with an electric turbocharger during combustion leads to cleaner engines. In addition, a more dynamic driving experience through the elimination of the turbo-lag makes electric turbocharging an attractive auxiliary device for the car industry. VAC has the optimum magnet grade for each scenario of application.”, says Alex Barcza, Product Manager Permanent Magnets. “We are happy to contribute to cleaner engines and therefore to a cleaner environment. “
