CERN – FCC Maintenance Robot

★ ★ ★ ★ ★
5.0 Customer Rating
Technical Challenge
We always had problems with overvoltage in the new maintenance robot for the future FCC particle accelerator. The manufacturer advised us to contact Akrodyn directly, as their programmable retrofit brake chopper had already been successfully used by other customers.
Solution
Thanks to the clever hardware upgrade, Akrodyn was able to help us ensure that the maintenance robot now runs absolutely reliably in no time at all.

Fitness Equipment

Nautilus Inc, USA – Electrical Fitness Equipment

5.0 Customer Rating
Technical Challenge
Since the introduction of selectorized weight stacks in the 1970s, most fitness equipment has only marginally evolved. People train against gravity using steel plates. Such training is time-consuming and inefficient.
Solution
We at Akrodyn want to change this. We have developed electric weights that, using an electric motor and complex software, precisely change the applied force at every angle and adjust the weight to optimally protect the user and guarantee training success. We have gained Nautilus as a partner for integration into an innovative training device.

"Akrodyn's fitness motor control platform has surpassed all competitors. The dynamics, smoothness, and safety features are incredible. They advised us very effectively on what is possible with electric weights. Akrodyn quickly adapted its technology to our US standards. Their team integrated seamlessly with ours. Their motor control technology is state-of-the-art."

HighSteps AG, Switzerland – Mobile Service Lift

★ ★ ★ ★ ★
5.0 Customer Rating
Technical Challenge
The 3rd generation of the mobile lift struggled with reliability issues. In addition, the previous Elmo motor controllers were discontinued (NRND), and the manufacturing costs did not allow for a satisfactory margin.
Solution
An elevator was equipped with an oscilloscope and other sensors, and intensive test drives were conducted. This allowed the problem to be quickly reduced to its root cause, which was then resolved in the field with a cost-effective retrofit kit.

"In the recently launched generation of our mobile high-tech service lift, failures occurred under strange conditions. Akrodyn equipped a lift with measuring electronics and was able to find and specifically rectify the fault. 13 lifts in the field could be retrofitted quickly and cost-effectively to prevent damage. Since then, they have been our long-term development partner."
