hofer Vienna and Pankl Turbosystems are jointly developing fully integrated electrified turbo systems for hybrid and high-performance powertrains, combining the turbomachine, electric machine, power electronics and control strategy into a single engineered system.
The companies say the idea is to avoid treating the e-turbo or e-compressor as an add-on subsystem. Instead, the high-speed electric machine—built with Form Litz winding technology—the power electronics, software controls and turbo machinery are being developed together from the start, with hofer handling the electric machine, electronics and software integration, and Pankl leading turbomachinery design, aerodynamics, materials, and high-speed mechanical integration.
According to the announcement, the integrated approach is intended to improve boost response, raise overall system efficiency and fit more cleanly into hybrid and high-performance architectures. The companies also say it can reduce cooling and packaging demands while improving volumetric and gravimetric power density, EMC and NVH performance, and long-term reliability.
Both companies stress that the development is being carried out to established industrial validation and quality standards, with an eye toward regulated and safety-critical markets. That makes sense: once you’re spinning an electric machine and turbo hardware at very high speed in a tightly packaged system, “integration” stops being a marketing word and starts becoming the whole engineering problem.
