Welcome to the

Geschichtskreis Motorenfabrik Oberursel

Historical Circle of the Motorenfabrik Oberursel

The branch of Wilhelm Seck’s Bockenheimer Mühlenbauanstalt, established in 1882, was the first mechanical engineering industrial plant in Oberursel before the Motorenfabrik was established on this site.
Today, it is the location of Rolls-Royce Deutschland, and is the last major industrial factory of its kind in Oberursel. As such, there is an obligation to capture, preserve and present the history of this Motorenfabrik as an essential part of the city of Oberursel. The historical Circle of the Motorenfabrik Oberursel , founded in 2010, operates the museum and is dedicated to this task. The factory museum was opened in 2002 and Rolls-Royce Deutschland being a major benefactor, makes a valuable contribution to the museum.



From the stationary engine to the turbofan jet engine

A journey of discovery in the Rolls-Royce Deutschland factory museum through the industrial history of the Motorenfabrik in Oberursel. 
The factory museum was officially opened in September 2002.
The opening was originally planned for October 2001 (as noted on the bronze plaque) but was postponed due to the consequences of the terrorist attacks on September 11, 2001. 

History of the Motorenfabrik Oberursel

Brief overview

The Motorenfabrik, founded in 1892, and since 2000 a site of Rolls-Royce Deutschland, is considered as being the world’s oldest active aircraft engine factory. The site goes back to 1882 to a factory built for the manufacture of grain milling machines. At the time it was the first mechanical engineering factory in Oberursel.
The company grew with the production of the stationary engine "Gnom", developed at the beginning of the 20th century, to the second largest manufacturer of motor locomotives in Germany. The orbital engines, built in Oberursel during the First World War, were used to equip the first German fighter aircraft, the most famous of which was the Red Baron’s Fokker three-decker or triplane.

The period between the world wars saw the manufacture of Deutz engines in Oberursel. These engines were installed in farm tractors, which advanced the mechanization of German agriculture. In addition, work was undertaken from 1941 onwards on the development of large-scale aircraft engines.
After World War II, the factory became a victim of reparations and was dismantled. The U.S. Army used it as a repair depot for the next 11 years.
At the beginning of the 1960s aircraft engine construction with various license productions and in-house developments moved into the factory.

A new era begun in 1990 with the development of the BR 700 series jet engines for regional and business jets.

After transition into Rolls-Royce Deutschland, the plant developed into a centre of excellence for rotating engine components, especially for compressor drums, compressor wheels in BLISK design and turbine discs.
