Complex speed measurement task on the roller tappet with customised sensors
Speed measurements under difficult environmental conditions:
For the case study, the Rotec Engineering team developed a customised miniature sensor for speed measurement on the roller tappet and used suitable measurement technology and analysis software to deriverecommendations for action.
Where can torsional vibrations in the electric drivetrain become critical?
This case study examines noise excitation in the electric drivetrain: where can torsional vibration cause critical dynamic loads, and which parameters should be measured?
