Innovative Drive for the Space Elevator – On the Way to Orbit with TQ Motors
Image source: WARR
The Scientific Workgroup for Rocketry and Spaceflight (WARR) at the Technical University of Munich is one of the largest student-led space organizations in Europe. With over 60 years of experience, multiple teams, and numerous international competition successes, WARR stands for ambitious space projects.
The founders of Isar Aerospace also gained early experience in the WARR student research group. In March 2025, Isar Aerospace – a spin-off from the Technical University of Munich – successfully completed the first test flight of its launch vehicle, marking the first rocket launch for orbital payload transport from Western Europe.
The Mission: A Space Elevator for the Future
As part of the GRAKSLER project, the WARR Space Robotics Team is developing a visionary concept: the space elevator. The idea: a stationary tether stretching from Earth’s surface to geostationary orbit, along which a climber transports satellites or payloads into space. The focus lies on creating a lightweight, powerful, and precise climbing vehicle.

We aim to increase range and payload – currently 100 kg payload at just 15 kg net weight. This requires a highly integrated drive system. «
Why TQ?
In the search for high-performance, compact electric motors, the team selected TQ-RoboDrive’s frameless servomotors. Their high torque density, flexible customization options, and excellent integration capabilities were key factors.
Compared to conventional servomotors, the TQ motor not only offers higher power density but also clear advantages when it comes to integration. «
The Role of the Motor
TQ’s frameless motor is a core component of the drive train. By integrating it directly into the climber’s structure, the team reduces both weight and volume – while enabling features such as waterproofing and optimized bearing design.

Outlook: Competitions & Development
The current GRAKSLER 5.0 is undergoing further development and is scheduled to compete in 2025 at international events such as EUSPEC and the Space Elevator Challenge in Japan – powered by technology Made in Germany.
