The world’s largest trade fair for testing technology and services for complete vehicles and components:
Automotive Testing Expo Messe Stuttgart: 21, 22 and 23 June 2022.
We were in Hall 10 – Booth 1770:
In the laboratory for Vehicle drives at the Faculty of Mechanical Engineering at the Bundeswehr University, old engine test benches were to be replaced by modern test benches with 250 or 350 kW power and the ability to use alternative fuels (methanol, ethanol, hydrogen), including an integrated measurement and automation system for teaching and research.
For this modernisation, it was important to deliver, on the one hand, a complete system consisting of test stand and measurement and automation system with high-quality load drives and a measurement and automation system based on an open architecture and algorithms for measurement, automation and evaluation.
As DASYM, we succeeded in meeting these requirements, so that we received the order to realise the project at the end of 2020.
These were 3 engine test benches: two with 350 kW and one with 265 kW load machines, complete with automation, control, measurement and safety technology.
The load units were equipped with our proven standard EC ODyn modules, and the automation, control and measurement technology was designed together with our partner OPV.
These 3 test benches have now been successfully put into operation and meet all the requirements set by the Bundeswehr University.
The cooperation with Prof. Dr.-Ing. Trapp and his staff was and is very good, so that the project management was a pleasure.
On April 1, 2022 we celebrate
10 years DASYM!
We are committed and successful in the market for test bench solutions since 2012.
We started with energy tax consulting and asynchronous machine modules, mainly for engine test benches and transmission test benches.
Then the product range was expanded with measurement technology, as well as automation and control.
In the meantime, together with good partners, we can also supply complete, well-functioning test stands, which we have already proven several times.
We are also well positioned for the future and will continue successfully,
flexible, competent, uncomplicated, committed to our customers.

Testing technology for new challenges
20.000 rpm – the new high performance test benches for e-motors and e-shafts
Future electric vehicles will make use of high-speed electric motors in combination with an appropriate power electronics and a reduction gearbox.
Electric motor test benches play a decisive role in the development of these drive systems. Among many other tests completet on the test benches, are dynamic retraction tests and efficiency analyses as well as endurance tests performed.
The DASYM drive and load machines of the series ECODyn E are intended for test bench applications in the e-mobility sector. The max. speed is 20,000 rpm. Their high torques and low mass moments of inertia offer speed gradients of up to 26,000 rpm/s and thus very good dynamics for demanding simulations.
Your success is our challenge!
a) Coolcon coolant conditioning from FEV for engine outputs up to 300 kW
b) ServoCraft throttle actuator
c) MORPHEE automation system:
