rotorLab has focused on the development of high-speed test benches and integrated test fields for electric and hybrid-electric drive systems. All individual components and modules of electric drives (shafts, rotors, motors, inverters, and battery systems as well as special applications) are tested on rotorLab's HiL (Hardware-in-the-Loop) test benches.

The rotational test benches for ranges up to 30,000 rpm and over 60,000 rpm feature drive systems from rotorLab, which enable highly dynamic four-quadrant operation as well as precision measurements across the entire speed range.

For efficient test bench operation, rotorLab uses a proprietary, high-precision quick-coupling system that ensures the safe and precise exchange of test items (shafts and rotors) as well as measuring hubs.

We also offer these systems to our customers to ensure the precise and reliable interaction of various machine elements in the drivetrain up to the test item in production or test operation within testing facilities.

The use of the highest quality components and measurement techniques has proven groundbreaking in the past for highly complex relationships in high-speed drivetrains regarding vibration measurement technology (NVH). rotorLab achieves this with its own unique competencies and an active network of highly specialized partners.

rotorLab test benches and test fields can be connected via integrated intermediate circuits to their own DC power supply (battery simulation) and battery storage in order to present optimal environmental conditions and avoid the cost-intensive feedback of operating current.

All test benches are equipped with system-specific safety technology and emergency running systems. In addition, specific burst protection and coupling elements are developed to take into account the dimensions and risks of demanding components.

rotorLab pursues the corporate goal of substantially increasing the efficiency and durability of rotors and drive components through specialized engineering services based on dynamic measurement technology and simulation calculations.

Dynamic measurements of geometries and vibration behavior are prerequisites for the development and precision balancing of individual high-speed rotors and contributing machine elements.

rotorLab has its own rotational measurement technology (orbitLab) and registers (orbitElements) for the relevant machine elements of electric and hybrid-electric drivetrains for aviation and automotive.

By combining high-quality laser and vibration sensors, rotorLab has designed a novel system for the dynamic measurement of rotors, which enables geometric measurement in multiple dimensions as well as the determination of imbalances and vibrations at high speeds of over 60,000 rpm.

In addition to rotor-induced vibrations, the measuring system also determines changes in component geometries at higher speeds.
Based on this system, rotorLab also offers measurement services in Brandenburg and on-site at the manufacturers and users of high-speed rotors and components.

In addition to measurement technology and automation solutions for test bench operation, rotorLab develops machine dynamic evaluation and simulation programs (orbitSim) for testing electric and hybrid-electric aviation and traction components for selected mission and operational purposes.

Special FMEAs developed by rotorLab uncover incorrect assumptions regarding plastic material behavior and burst speeds of rotating machine elements. These FMEAs can also be applied to the combination of assumptions or the assessment of the durability of motors, generators, hybrid systems, and batteries.
