At high rotational speeds, rotor bending occurs, directly impacting operational reliability — increasing noise levels, reducing bearing lifespan, and compromising the overall dynamic stability of the system.
In collaboration with leading experts, we are completing the development of our own methodology for compensation of bending modes in high-speed rotors. Through advanced displacement sensing and precision software-based calculations, we define the optimal material removal to ensure maximum dynamic stability. Our method enables accurate compensation of the first bending mode already at lower speeds — a critical step especially for long and high-speed rotors.
Validated result:
A test rotor, originally balanced as a rigid rotor with a maximum speed limit of 85,000 rpm, achieved stable operation at 115,000 rpm after applying our compensation method. The limiting factor became the proximity to the material’s strength threshold.
Vibrations, noise, and operating temperature were all significantly reduced.
Key benefits of the methodology:
✅ Higher operational speed and broader stable operating range
✅ Significantly reduced noise, vibration, and thermal load
✅ Extended lifespan of bearings and rotating components
✅ Improved overall system reliability and performance
✅ Faster, more efficient balancing process
We plan to implement this methodology primarily in our own products. Once fully developed, we will also offer it as a service to our customers and partner companies.
In parallel, we are working on integrating both static and dynamic balancing of rigid rotors directly into system design — a step toward even more compact, reliable, and efficient high-speed machines.
