Use of an electrical compressor to improve torque and transient behaviour 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.

Design, commissioning and testing of gas bearing turbo compressors with gases other than air

20. September 2016

Oil-free turbo compressors with gas bearings are not only used for the compression of air with 1 bar ambient pressure, but also for other pressure levels or refrigerants.

Direct drive for dental/medical hand pieces and micro-machining

18. July 2016

To machine very small work pieces (micro-machining) or for ergonomic reasons in dental and medical drills, the head of the machining spindle or the hand piece has a limited size. The electrical motor is only allowed to grow in one lateral direction if a direct drive is used.
