Converters for sensorless control

All our converters allow for sensorless control of turbo compressors and motors up to highest speeds. The solution from one single source guarantees optimal compatibility of the converters and the turbo compressors and motors, thus minimizing losses in the turbo compressor or motor and ensuring high converter efficiency and a smooth startup process.

  • Sensorless control for highly dynamic speed adjustment
  • Minimal losses in the converter, turbo compressor and motor
  • Smooth startup process
  • Gas bearing diagnostics
  • Custom adaptations possible

Magnetic-bearing choppers

Our magnetic-bearing choppers can be operated in a vacuum, in air or in a noble gas atmosphere. This allows us to achieve maximum speeds and chopper frequencies. They are used in infrared, laser and X-ray applications and offer highly stable speed control and lock-in functionality.

  • Maximum speed stability
  • Operation in vacuum
  • Minimal vibration emission
  • Maintenance-free
  • Custom specific chopper discs and mirror rotors

Cooling of a pixel tracker using gaseous helium

Cooling pixel detectors in experimental particle physics with helium requires the oil-free recirculation of the rare gas. The concept presented in the following paper is not limited to pixel detector applications and can be used to cool any surface with respective heat-densities, only limited by shaping the helium gas flow with the turbo compressor CT-1050-He.

High-speed magnetic bearing chopper for infrared nanospectroscopy

Infrared (IR) nanospectroscopy is a non-destructive method for the analysis of molecular structures below the wavelength scale. It is used in a broad range of research applications spanning from biochemistry to geology. A magnetic bearing chopper is a core component to bring this IR method to the next level of spatial resolution. It provides the beam chopping functionality in vacuum, at high frequency and with very low jitter.
