Celeroton AG


The Swiss high-tech company Celeroton, with its headquarters in Volketswil on the outskirts of Zurich, is the leading manufacturer of ultra-high-speed electrical drive systems with speeds up to 1 million rpm.

Faster, smaller, lighter and more efficient: Celeroton’s turbo compressors, converters and permanent-magnet motors are designed for highest energy efficiency and lowest volume and weight. The innovation lies in the interdisciplinary know-how in the areas of mechanics, electromagnetics, electronics, control systems and software which allows for outstanding solutions in terms of compact size, efficiency and control performance.

Application areas for Celeroton's drive systems are medical and dental tools, air supply for fuel cells, rotating mirrors and prisms for optical systems, lasers and scanners, micromachining spindles, generator and electronics for gas turbines, expander turbines for energy recovery, flywheels and many more.

Many applications cannot be covered by a standard product range, therefore we offer a custom development service along with our product portfolio. Both in the fields of turbo compressors and motors, together with the matching electronics, our specialists will accompany you step-by-step through the development.
