Our customers benefit from our decades of experience in developing specialized electric machines. Individually tailored specifications can be analyzed using multi-parameter optimization algorithms. From this, we develop an optimally manufactured machine concept, followed by design and prototyping.

We enjoy collaborating with you during the transition of development projects to series production. Krebs & Aulich GmbH ua together.
