Product & technology overview of Celeroton

24. February 2016

Speed, torque, power, mass flow, volume flow, pressure ratio or pressure difference - absolute or relative? These are just some basic specifications of an ultra-high-speed motor or turbo compressor. To clearly display our product portfolio and to facilitate the selection, we have developed the two figures shown below. They depict our available products and their operating ranges, as well as the scope of our technology.

Comparison of converter topologies and modulation schemes for high-speed motors

09. November 2015

The 2-level converter topology in combination with pulse width modulation (PWM) is the standard converter for rotational speeds up to several thousand revolutions per minute (rpm). When the application needs rotational speeds up to several hundred thousand rpm or has extreme motor efficiency requirements then other converter topologies and modulations schemes must be considered. Normally pulse amplitude modulation (PAM) is the optimal choice. What are the advantages and disadvantages of these two modulation schemes? Here is a guide to help in making the best selection.

Higher rotational speeds for micro gas turbines

05. February 2015

High speeds are not only required in applications where a motor is used to drive a compressor, micromachining spindle or a mirror. More and more high-speed generators, with speeds of 300,000 rpm and beyond, are finding their way into gas turbines for stationary or mobile power generation, also called gas turbine generator systems.
