Turbo blowers and radial compressors generate significant energy savings in sewage treatment or power plants. They are also in demand in the area of high-vacuum technology or in turbo molecular pumps where it is essential to ensure extremely precise drive control.
This is necessary, especially at the high speeds at which the turbo blowers and radial compressors operate, in order to keep the heat generated by the high-speed motor under control at all times. KEB makes this possible with its COMBIVERT F6 drive controller. Building on applications in the area of process technology, the F6 offers the required performance through high switching frequencies of up to 16 kHz and output frequencies of up to 2000 Hz. It is also flexibly adaptable thanks to a wide range of configurable, sensorless safety options, encoder interfaces and efficient cooling concepts.
The Z2 sine wave filters, which are coordinated with the F6 and are specially designed for use at higher frequencies, provide protection against overheating, reduce EMC stress and thereby increase the service life of turbo blowers and radial compressors.
