history

The engineer Christian Dunker initially dealt with the development of small engines at home in Bad Godesberg . In 1950 he founded the company Christian Dunker Präzisions-Kleinstomoten in Oberbreisig and started production with three employees the following year. On March 3, 1954, the company asked the municipal administration of Bonndorf about the possibility of establishing a business there and on February 10, 1955, concluded a corresponding contract in the town hall. Under Mayor Leo Speck, the city provided a large amount of money for the settlement, which it was able to generate through extraordinary logging . After moving, the company, now known for short as Dunkermotoren , had 400 m 2 and increased the number of its employees from 30 to 60. The company was successful, opened a second production facility in Rottweil in 1956 and followed by branches in Ewattingen , Sulzburg and Lörrach . The production in Rottweil was closed again in 1960, but the workforce grew to 674 employees by November 1963.

In 1963 Christian Dunker sold the majority of his company shares to Union Carbide Corporation (UCC) and converted the company into a GmbH . Co-partner Alexander left the company. In the same year a camera from Leica Camera was presented at the international radio exhibition in Berlin , which was operated with a Dunker motor.

On July 2, 1966, the company founder had a fatal accident in a car at the age of 50. Three years later, in 1969, Union Carbide sold its stake in the American conglomerate International Telephone & Telegraph Corporation (ITT), which subordinated the company to its electrical engineering subsidiary Standard Elektrik Lorenz AG (SEL) in Stuttgart . In the same year, Dunkermotoren were also used for camera work during the first manned moon landing . In 1977 the planetary gearbox was launched. In 1985 the "4-phase brushless DC motors" were introduced.

After the sale of Standard Elektrik Lorenz to the French Compagnie Générale d'Électricité (CGE) at the end of 1986 and its subsequent break-up, Dunkermotoren remained with the corporate core around communications technology, which from 1993 traded as Alcatel SEL AG .

In 1999 Dunkermotoren presented the first brushless DC motor with integrated electronics. A market study by IMS Research in 2007 and 2015 named Dunkermotoren as the world market leader in the field of brushless motors with integrated electronics.

As a result of the merger of the Alcatel SEL parent company in France, which had meanwhile changed into the pure telecommunications supplier Alcatel SA , with the American Lucent Technologies, Inc. , Dunkermotoren belonged to the newly formed German subsidiary Alcatel-Lucent Deutschland AG from January 1, 2007 . An industrial connection that went beyond ownership, as under Standard Elektrik Lorenz , no longer existed in the Alcatel-Lucent group. All other areas, just like Dunkermotoren, no longer part of the core business of telecommunications equipment, had been gradually outsourced and sold by the management in France years before.

In 2007, Dunkermotoren opened a manufacturing facility in Taicang , China , and a year later in Crystal Lake , United States.

In the course of the sale of the shares for 145 million euros to Triton Beteiligungsberatung GmbH , a company of the German-Scandinavian private equity company Triton Partners , Dunkermotoren GmbH became independent from Alcatel-Lucent Deutschland AG in 2009 . Also in 2009, Dunkermotoren and the neighboring electronics company Hectronic signed a training pact for the training cooperation "HeDu".

In 2011 Dunkermotoren GmbH opened a new production facility in Subotica , Serbia and took over Copley Motion Systems in Basildon , UK . In 2012 Triton sold its shares for 250 million euros to the American manufacturer of electronic and electromechanical instruments Ametek, Inc. In mid-2013, the three previous managing directors Nikolaus Gräf, Volker Brunner and Frank Guckelberger announced at the same time. Uwe Lorenz and Markus Roth then took over the management. In 2014 the Dunkermotoren subsidiary in the USA moved to Mount Prospect, Illinois. In 2015, Linear Systems production moved from Basildon in Great Britain to the headquarters in Bonndorf. In the same year, a competence center for blind drives opened at the location in Serbia. At the beginning of 2016, Dunkermotoren expanded the production facility in Subotica by 900 m².

In June 2016, Uwe Lorenz was given a new position within the Ametek Group at the sister company MAE in Robecco sul Naviglio near Milan , so that the company was continued by Markus Roth alone. Matthew C. French has been running the company as interim managing director together with Uwe Lorenz since the beginning of October 2017. Matthew C. French is a Senior Vice President at Ametek AMS.

In 2016/2017, Dunkermotoren launched the first brushless DC motor with integrated electronics and a continuous output of 1100 watts at 24 VDC - the "BG 95 dPro". In addition, the company's re-entry into the ironless motor market was established with the BGA22 axial flux motor. Dunkermotoren continues to be the market leader in the field of integrated, smart BLDC servo drives.
