Laboratories: Test-Benches and Additional Devices

Test-Benches:
In our laboratories, more than 20 test-benches for variable ranges of power, torque, and speed are available. All of the test-benches are designed for 4Q-operation and are provided with high-precision measurement equipment for speed and torque.
Some of most specific importance are the following test-benches, of which detailed data and characteristics are provided at: test-benches (pdf)
