The history of Sumitomo Drive Technologies dates back to 1888. Sumitomo, who had been invested in the copper industry in Japan already, opened the Besshi Copper Mine in 1691. The “workshop”, which was created for manufacturing and repairing machines and instruments used in the Besshi Copper Mine, was the origin of Sumitomo Drive Technologies. In 1938, we made a technical alliance with Mr. Lorenz Braren, who invented the Cyclo Reducer in Germany, and is now the basis for our main products in the marketplace today. Since then, we have expanded our product lineup to include compact gearmotors, large gearboxes, and speed reducers for precision control; all of which are handled by our facilities and sales offices around the globe. Currently, our global footprint includes 10 production facilities, 30 assembly plants, over 200 sales offices. In 2018, Lafert Group, an industrial motor manufacturer in Italy, became a wholly-owned subsidiary and has expanded our business in the electrical motors and controls industries. Sumitomo Drive Technologies will continue to provide customers with solutions that match our historic reputation and the evolving industries that we serve.
