Tetrastruct stands for technical excellence in balance – both literally and figuratively. Our work is based on the principle of the tetrahedral structure: four equally important, mutually supportive focal points that form a stable and resilient whole. This balance of forces is not just a physical model, but the methodological foundation of our approach.
Our four core areas – Consulting, Services, Training, and Trade/Global Sourcing – act like the corners of a tetrahedron. Each area is strong on its own, but only through interaction do they unfold their full potential. The communication between these forces creates synergies that directly benefit our customers:
-
Consulting: We provide expert advice in all aspects of drive technology – from electric motors and power/energy design to inverter and control system selection and supply chain optimization.
-
Services: We support implementation – with technical system design, programming, layout development, and procurement of complete drive systems.
-
Training: We share our expertise – through practice-oriented seminars and customized training formats tailored to your team and challenges.Trade & Global Sourcing: We procure what you need – through an international network of suppliers for components from the entire field of drive technology.
What makes us unique is the holistic integration of these areas. We don’t look at challenges in isolation – we solve them systemically. This leads not only to better solutions but also to more sustainable partnerships.
To further expand these strengths, we are planning to open a foreign base in China this year. From there, we can handle international projects more efficiently, with less bureaucracy, and closer to the market – another step toward true global agility in the service of our clients.
Tetrastruct – where technology and structure are in balance.
About Us
Experience Profile – Prof. Dr.-Ing. Reinhard Müller-Syhre
Our vision at Tetrastruct thrives on experience, connectivity, and technical depth.
A central element of this philosophy is the personal and professional profile of our managing director, Prof. Dr.-Ing. Reinhard Müller-Syhre. His extensive work in various areas of drive technology forms the foundation of our systemic approach.
A clearly structured, chronological "Experiogram" illustrates his career spanning over five decades: from academic research and industrial development to international consulting. His expertise ranges from embedded control, hardware development, drive regulation, and power electronics to CAD/simulation and the design of complex electric machines and gear systems.
He held leadership or advisory roles at prestigious companies such as SIEMENS, BMW, Magna, Continental, IWIS, Kinshofer, Clean Mobile, and Hirschvogel. The color-coded structure of the Experiogram provides an immediate visual overview of his technical focus and roles. Selected photos and videos of real-world projects document successful implementations in railway drives, e-bike systems, high-performance inverters, and gear development.
Since 2014, he has been managing director of Tetrastruct GmbH, specializing in contract development of electric drive systems, inverter design, motor dimensioning, and embedded programming. He is also active as a lecturer and speaker in the fields of drive technology, mechatronics, and system integration.
A major milestone ahead is the planned foundation of Tetrastruct China Ltd., aimed at bringing development, sales, and supply chaining even closer to international markets.
This experience profile is more than a résumé – it is a living example of what drives Tetrastruct every day:
holistic thinking, technological depth, and global implementation
