ERNST

High-speed adaption and powertrain

The connection between the test bed and the DUT, also known as the shaft connection, is usually put together individually. Many factors, both regarding the DUT and the existing test bed, are taken into account when choosing the proper adaption components.

At ERNST, various approaches are discussed together with the customer and concepts are adapted to the respective requirements in order to be able to offer the customer a technically optimal solution.

This allows the customer to benefit from a wide range of already developed solutions that have been in use for years.

The in-house production allows for fast response times and enables a holistic support from the design to the finished product.
