Energy saving potential with oil-free turbo compressors in fuel cell systems

06. November 2017

Due to their compact design and high efficiency, oil-free electrical turbo compressors are ideally suited for mobile fuel cell systems, e.g. in vehicles and thus have great energy saving potential compared to standard compressors. This article presents a comparison with other compressor technologies and the potential for improvement in converter topology.

Model-based control of an electrical compressor to increase low-end torque and its impact to fulfil “real drive emissions” of diesel engines

03. November 2017

Additional electrical compressors have long been considered to enhance response behavior of engines. In combination with appropriate software and motor parametrization, an additional compressor can also reduce pollutant emission. Robert Bosch GmbH works on the development of the required software and components for the use of an electrical turbo compressor for diesel engines. Bosch has successfully tested, combined with the respective control, the Celeroton turbo compressor CT-14-1000 in a diesel motor test rig.

Application examples of the magnetic bearing CM-AMB-400 motor for optical applications

27. June 2017

High speed rotating elements, such as disc shaped rotors crossing a beam, infrared and x-Ray-choppers; diffusor-discs in interferometers; mirrors in high-speed cameras or laser systems, are used to deflect a beam. The modular assembly of the magnetic bearing motor CM-AMB-400 allows the use of an application specific rotor. The concept of the magnetic bearing motor is such that a beam can be guided in radial or axial direction to the rotor to be deflected or chopped by the rotation.
