Our customers benefit from our decades of experience in developing specialized electrical machines. Customized specifications can be mapped to multi-parametric optimization algorithms. From this, we develop an optimal machine concept for production, followed by design and prototyping.

When transferring development projects to series production, we are happy to work with Krebs & Aulich GmbH together, among others.
