Frequency Converters for Turbo Compressors, Turbo Blowers and Pumps

The Challenges

In the field of turbomachines, the system's efficiency can be continuously improved by increasing the system speed or omitting the gear. Hence, it is necessary to use appropriate high-speed motors instead of the slowly rotating standard motors. Standard frequency converters are not capable to drive high-speed motors adequately due to the necessary high rotating field frequency and the low rotor volume. The frequency converters by SIEB & MEYER are customized for operating high-speed motors. They provide the necessary rotating field frequencies and guarantee a low motor heating by means of special control technologies. The motor heating has a significant impact on the system's efficiency and the service life of motors and bearings.
