About Küenle Antriebssysteme
Küenle Antriebssysteme is a family business founded in 1936 and based in Hemmingen near Stuttgart, specialising in electric drive systems. The product portfolio includes electric motors in aluminium and cast iron versions, asynchronous generators, gear motors, vector-controlled and compact drives as well as frequency inverters of the KFU tronic series. In addition, the company manufactures customer-specific custom developments based on a modular building block system, including winding calculation, special shafts, special flanges, software programming and machine simulation. In its own winding manufacturing facility, rotor and stator windings are produced from copper up to 400 kW and frame size 400, including special windings up to insulation class C (>180 °C). Mechanical manufacturing includes turned parts, milled parts, friction welding, commutator machining, jig and fixture building and prototypes. Service offerings range from maintenance, repair and commissioning to pump service (partner of Xylem/Lowara) and 24-hour on-call emergency service; a performance test bench with up to 500 kW is available for drive testing. Customers come from drive technology, conveying technology (Demag service base), electrical machine engineering and water circulation/pump technology.
