Our passion since 1931 – driving the world and shaping the future
The story of Süddeutsche Elektromotorenwerke (SEW) starts with four people – an ingenious engineer, a bold and entrepreneurial couple, and their daughter. Over the decades, thousands of others have followed in their footsteps. It is these people who have collectively made the company what it is today – one of the world's leading suppliers of drive and automation technology. Find out more about the people behind the machines and their ideas for driving the future.
The master precision mechanic, who had learned his trade for electric motors in the USA, opened a small repair workshop in Bruchsal in 1913. This became Albert Obermoser AG, which, however, ran into financial difficulties as a result of the difficult post-war years. Obermoser had to sell his company to an industrial group, which also began to falter. However, the bank sees future opportunities for Obermoser AG and plans an overhaul. By this time, he has already left Albert Obermoser AG and continues his entrepreneurship with Albert Obermoser KG.
In 1927, the banker Christian Pähr is commissioned to restructure Albert Obermoser AG. When Obermoser left his former company and founded Albert Obermoser KG at the same time, Christian Pähr initially continued to manage the AG of the same name. On June 13, 1931, he took over the manufacturing rights and founded his own company, Süddeutsche Elektromotorenwerke. He died just four years later in 1935 at the age of 70.
Christian Pähr
Leta 1927 je bil bančni poslovnež Christian Pähr pooblaščen za sanacijo družbe Albert Obermoser AG. Ko je Obermoser izstopil iz svoje prejšnje družbe in hkrati ustanovil družbo Albert Obermoser KG, je Christian Pähr sprva še naprej vodil družbo z istim imenom. 13. junija 1931 prevzame proizvodne pravice in z družbo Süddeutsche Elektromotorenwerke ustanovi svoje podjetje. Le štiri leta kasneje, leta 1935, umre v starosti 70 let.
Establishment of SEW on June 13, 1931
Despite its pioneering technology, Albert Obermoser AG found itself in financial difficulty in 1929 due to the Great Depression. Banker Christian Pähr acquired the bankrupt estate and founded Süddeutsche Elektromotorenwerke SEW on June 13, 1931. This picture shows the workforce. Shortly after the company's founding, the staff grew to 35 employees.
Typical of the time – the name and quality seal of the new company
Although the company was founded at the worst possible time, it survived the Great Depression and grew. As the Director of SEW, Christian Pähr earned 441 Reichsmarks per month, while the monthly salaries and wages of his employees ranged between 24 and 199 Reichsmarks.
The daughter of the company's founder helped her mother run SEW after his untimely death and was appointed an authorized signatory in 1941. She married army officer Ernst Blickle in 1942.
After a brief period as a prisoner of war, Ernst Blickle returned to Bruchsal. When his mother-in-law died in December 1945, he took over the management of SEW. As a visionary, Blickle was quick to realize the potential of the technology and set about acquiring the expertise he would need. He consistently leveraged both to grow his company.
Rainer Blickle, who was active and based in Brazil for SEW, returns home after the death of his father. As Managing Partner, he is responsible in particular for the markets and subsidiaries in India, South America, and Europe. Unlike many other companies at the time, he remained at his traditional location in Germany and at the company headquarters in Bruchsal, where he gradually invested in new buildings and production halls. By the time he left the company management in 2013, the first electronics production facility, the Ernst Blickle Innovation Center (EBIC), the DriveAcademy®, the Plant for Large Gear Units, and many other plants around the world had been built in Bruchsal. He died on March 3, 2021 at the age of 73.
Jürgen Blickle has been successfully managing the company's fortunes as sole managing partner for over 10 years. Mourning and celebratory moments often go hand in hand. Following the death of his brother Rainer at the beginning of March 2021, Jürgen Blickle celebrated two milestone anniversaries in the summer of 2021: his 70th birthday and the 90th anniversary of SEW-EURODRIVE. Following the family tradition, Jürgen Blickle is also committed to Germany as a location. The new south and north plant halls in Graben-Neudorf, the new electronics production facility, large parking garages for employees in Bruchsal and Graben, a company daycare center, the infrastructure center, and measures still under construction or in the planning stage are clear testimony to this.
In the early 1920s, factory halls were dominated by drives with transmission belts. Not only was the noise level correspondingly high, but also the risk of injury. Not to mention the high energy requirements. A pioneering invention by Albert Obermoser, patented in 1928, finally offered an alternative to these drive belts. The drive unit, which Obermoser called a “Gearmotor”, couples the motor to the gearbox - a spur gear. The advantage: the solution is compact and space-saving, runs much more quietly and precisely and also saves energy.
SEW-EURODRIVE's most groundbreaking invention in the field of drive technology came in the mid-1960s: The modular system for gearmotors is still one of the most important pillars of the company's success today. A manageable number of standardized individual parts and component groups form the basis for countless possible combinations for every customer requirement. Quick assembly and fast delivery give SEW-EURODRIVE an important competitive advantage.
When SEW-EURODRIVE took over Albert Obermoser KG in 1973, new motors, motor types, and corresponding accessories were added to the portfolio. They included V-belt and friction-wheel variable-speed gearmotors, clutches, brakemotors, DC motors, power converters, and additional electrical components.
At HANNOVER MESSE 1977, the company also presents another invention: the Parallel shaft gearbox with its high degree of efficiency now enables use with greater power and is significantly quieter than previous gearbox designs.
V začetku 80. let so osebni računalniki osvojili pisarne razvijalcev in konstruktorjev. Z začetkom razcveta CAD-tehnologije je postalo tudi konstruiranje pogonov bistveno enostavnejše in hitrejše. Tako je v 80. letih elektronika vstopila ne le v pisarne, temveč tudi v pogonsko tehniko in s tem zaznamovala začetek industrijske avtomatizacije. Tudi pri podjetju SEW-EURODRIVE so zdaj motorna gonila krmilili frekvenčni pretvorniki. Elektronski krmilniki niso dolgo čakali na svoj prihod.
Ernst Blickle se odloči, da pogonske elektronike ne bo več kupoval, temveč jo bo v podjetju SEW-EURODRIVE razvil in proizvajal sam. Leta 1991 je bila sprejeta odločitev, da se v Bruchsalu za ta namen vzpostavi nova tovarna za proizvodnjo elektronike. Celostni koncept podjetja, razvit v naslednjih letih, postavlja nove standarde v pogonski tehniki. Sem spadajo tudi gonila z majhno zračnostjo in servomotori, ki so od 90. let naprej razširili ponudbo.
Od decentraliziranega pogona MOVIMOT®® je le korak stran do prve pogonske enote, ki v enem ohišju združuje motor, gonilo in pretvornik. Z MOVIGEAR®® – prav tako predstavljen na sejmu HANNOVER MESSE – se od leta 2005 mehatronika uveljavlja v pogonski tehniki. Leta 2011 se je po zgledu MOVIGEAR® pridružil elektronski motor (motor in pretvornik v eni enoti).
Dve leti po predstavitvi MOVIGEAR® je podjetje SEW-EURODRIVE na sejmu HANNOVER MESSE na impresiven način dokazalo, da je sposobno samostojno izdelati tudi pionirsko platformo industrijskih reduktorjev – kot običajno po preizkušenem modularnem principu tega specialista za pogonske sisteme. Da bi lahko zadostili naraščajočemu povpraševanju po teh gonilih, v Bruchsalu nastaja nova proizvodna tovarna za velika gonila.
Tudi danes se preizkušeni modulni princip podjetja SEW-EURODRIVE izkazuje kot napreden. Z MOVI-C® podjetju uspeva generacijska zamenjava. Z MOVI-C® so med seboj usklajeni ne le pogonska tehnika, pretvorniki in krmilna tehnika, temveč tudi programska oprema za inženiring in vnaprej programirani programski moduli. Proizvodna zmogljivost prvega tovarniškega obrata za elektroniko, ki je bil dokončan leta 1999, kmalu ni več zadostovala. Zato je leta 2017 nova gradnja v Bruchsalu postala neizogibna.
Da bi v prihodnosti lahko bolje zadovoljili potrebe aplikacij, kot so bobnasti sušilniki ali stiskalnice za iverne plošče, SEW-EURODRIVE na podlagi svoje serije P in drugih preizkušenih komponent razvija novo platformo industrijskih menjalnikov. Posebno kompaktno izdelano koaksialno planetno gonilo omogoča poleg visokega števila vrtljajev tudi zmogljivost in mejno toplotno obremenitev, ki sta na trgu doslej še nedosegljivi, in to na majhnem prostoru.
