Rotor dynamics

Rotor dynamic design and balancing: the combination of theory and practice as well as exact science and accumulated experience is the key to success.

Rotor dynamics

Rotor dynamic calculations must be performed to guarantee safe operation of the rotor. Rotor dynamics are directly related to the motor and gas bearing design, as the size of the motor’s magnet has a direct influence on rotor dynamics performance, and deformations due to bending modes and eigenmodes must be taken into account in the bearing design. Celeroton uses its own design software for the rotor dynamic design, which is integrated in the gas bearing design software. The rotor dynamic design is also strongly linked to the manufacturing and balancing of the rotor. Celeroton combines the know-how in rotor dynamic design, the balancing and the validation of rotor dynamics via sensors under one roof. This unites theoretical and practical innovation, expertise and experience at the highest level.

Stable gas bearings

Celeroton considers the required operating range of its gas bearings in an early phase of the system design and thereby trial-and-error design loops. This allows for fast time to market in customized systems. Furthermore, Celeroton validates the gas bearing stability in serial production. Therefore, at Celeroton, each compressor comes with a gas bearing quality control.

Multi-stage control and operation of miniaturized gas bearing turbo compressors in gas separation plants

For efficient production and for avoiding long transport distances, our customer operates gas separation plants directly at it's clients' sites. These plants typically use turbo compressors with several 100 kW electrical power. To optimize these plants and to improve gas separation methods, pilot plants are operated in a laboratory environment. Learn more about this in the article...

Application example: Towards optical switches based on high-speed magnetic bearing motor CM-AMB-400

A number of emerging applications ask for a dramatically improved performance of femtosecond laser systems concerning pulse energy. Due to limitations in the amplifier medium, further improvements within the laser source are increasingly challenging. Stacking of multiple amplified pulses via methods such as Stack-and-Dump seems to be a possible solution.
