Our Services

Development

Various patented technical solutions guarantee our leading role as a supplier of very low-inertia and highly utilized asynchronous machines. In cooperation with colleges and universities, development is constantly being driven forward and new trends are being set.

Manufacturing

We manufacture with state-of-the-art technology and craftsmanship. Thanks to our versatile and modern machinery, we achieve a vertical range of manufacture that is rarely offered by medium-sized companies today.

Construction / Engineering

While at the Homberg (Efze) site we focus on the design and construction of customer-specific special motors for various industrial sectors, highly utilized electrical machines are developed in Dresden for test benches in the automotive industry, among other things.

Test field

In our test field, measurements according to VDE standard and special measurements according to customer requirements are possible. For load measurements on the mains or frequency converters, 6 load machines with different characteristic curves are available.

The company AKH – Antriebstechnik KATT Hessen GmbH was founded in 2002 by renaming the KATT-MOTOREN-FABRIK, founded in 1924, and the development company AKS.

The headquarters of the AKH is located in Homberg (Efze) in northern Hesse. There is another development office in Dresden.

Since November 2014, AKH has been part of the Brazilian WEG Group, one of the leading international manufacturers of electric motors. 

Our design offices develop special solutions for a wide variety of applications.These special engines are produced in Homberg (Efze) and sold worldwide.
