OROS Balancing Solutions are software modules for balancing rigid and flexible rotors. These modules are well-suited for shop balancing or in-situ field balancing. They are designed to run on OROS analyzers

2 modules are available:

• The Single/Dual plane software module is particularly suited for shop or field balancing of rotors operating in their rigid body region (well below their first critical speed).
• The Multiplane software module is designed to balance rotors above the first critical speed: meaning in the region where the rotor deforms and reaches its first bending mode.
