The objective is not an add-on solution, but a fully engineered system approach in which the turbomachine, high-speed electric machine featuring advanced Form Litz winding technology, high-efficiency power electronics, and control strategy are developed as an integrated system from the outset.

hofer Vienna is responsible for the complete system development — from the design of the electric machine and power electronics to the full electrical and software integration into the overall system architecture.

Pankl Turbosystems leads the turbomachinery design and development, including aerodynamics, materials technology, and high-speed mechanics, as well as the integration of the electric machine into the boosting concept.

The requirements for modern propulsion systems are increasing: higher power density, stricter emissions and efficiency targets, reduced packaging space, and growing electrification. Electrified turbo systems are a key enabler in addressing these challenges. They improve boost dynamics, enhance overall system efficiency, and enable seamless integration into hybrid and high-performance architectures, while reducing cooling and packaging demands.

The development follows established industrial quality and validation standards and, from the outset, takes into account requirements typical of highly regulated and safety-critical markets.

For the market, this translates into high volumetric and gravimetric power density, optimised efficiency in both boost and recuperation modes, improved EMC and NVH performance, increased reliability and lifetime, and reduced integration risks through a harmonised system architecture.

In projects with demanding documentation, certification, and validation requirements, fully integrated system concepts are becoming increasingly important. Electrified turbo systems make a measurable contribution to improving efficiency and reducing emissions in modern propulsion systems. They enable significant downsizing without performance loss and improve transient efficiency in hybrid architectures. The result is a solution that is not only high-performing, but also industrially robust and scalable over the long term.
