Histoye VEM Sachsenwerk


Change of managing director on April 1, 2012/Strategic orientation: Full-service provider of controlled drive systems under VEMoDRIVE


VEM Sachsenwerk looks back on 125 years of electrical engineering in Dresden. Commissioning of a 6 MW large machine testing facility including a new assembly hall with 1440 m². The core business is based on the production of special drives and drive solutions for individual industrial applications. Development of wind power generators up to 7 MW.

2010 /

The global financial crisis is causing a dramatic drop in sales, especially in the wind turbine sector up to 2.5 MW.


VEM Sachsenwerk is celebrating its 100th company anniversary. VEM Sachsenwerk operates on the international market as a provider of medium and high-voltage electrical machines with an output of up to 34,000 kW. The company occupies a market leadership position with its range of double-fed wind power generators from 1.5 to 5.4 MW.


The 1000th wind power generator will leave the company premises in autumn.


With the delivery of the world's largest compressor drive with an output of 23.5 MW for the LDPD project in Basell/France, VEM Sachsenwerk has once again achieved a top technological achievement.


The Sachsenwerk will be given back its traditional name on July 1st and will now be called VEM Sachsenwerk GmbH.


On January 1st, the company is privatized and goes into the hands of the Blaubeuren entrepreneurial family Dr. Adolf Merckle about.


The orders have a volume of 20.82 million euros. This resulted in a reduction in staff numbers from 613 to 403 employees.


On June 29th, the company was spun off from the stock corporation as VEM-Elektrotriebe GmbH.


In July, the trust assigns VEM-Antriebstechnik AG to Horst Plaschna Management GmbH & Co. Beteiligungs- und-verkaufs KG Berlin.


On June 30th the company merged with VEM-Antriebstechnik GmbH. Your turnover amounts to 61.16 million euros. 2,105 employees now work in the company.


The GDR combine with all associated companies will be converted into the stock corporation VEM –Antriebstechnik AG on April 5th. Previously, the 15 companies of the Elektromaschinenbau Dresden combine were converted into limited liability companies (GmbH) at the same location. The Sachsenwerk now operates as VEM Sachsenwerk GmbH Dresden. As its own development, VEM Sachsenwerk is bringing the VEMoDUR VPI-155 and VPI-200 insulation systems onto the market.


On July 13th, the parent company VEB Elektromaschinenbau Dresden was formed. This company includes the companies Sachsenwerk, Elbtalwerk Heidenau, Elektromotorenwerk Dresden, Elektromotorenwerk Ost and the research and development center.


In the 1980s, the Sachsenwerk occupied an important position in the GDR economy as the sole manufacturer of medium and large electrical machines. The machines are used primarily in heavy machinery and plant construction, in vehicle and shipbuilding, in the coal and energy industries and in the chemical industry. In August 1#980, the 25th 10 MVA synchronous railway converter will be handed over to the Deutsche Reichsbahn on time and in good quality. At 145 tons, this product is the largest and heaviest product that had been manufactured by the GDR's state-owned electrical engineering company to date.

At 145 tons, this product is the largest and heaviest product that had been manufactured by the GDR's state-owned electrical engineering company to date.


The Sachsenwerk insulation system is officially registered with the trademark “VEMoDUR”.


The first standard engines roll off the production line in the new factory. The first single-phase alternating current traction motors for 16 2/3 Hz locomotives are manufactured.


This year, construction of the new standard engine factory, which is designed according to the most modern aspects, begins on the factory premises.


After the factory was returned to the GDR, the company was incorporated into the HV EM (Head Office for Electrical Mechanical Engineering) at the beginning of the year. Its name is now VEB Elektromaschinenbau Sachsenwerk Dresden-Niederselitz.


The popular uprising of June 17th also spread to Dresden. In the city, the protest march is led by 2,000 Saxon workers. He calls for the government to resign, free and secret elections and the release of all political prisoners. The intervention of the Soviet military ends the uprising.

Until the end of the year, the Sachsenwerk operates as a SAG company (Soviet Joint Stock Company) and belongs to the Soviet AG “Kabel”.


The company is participating for the first time in foreign trade fairs in Stockholm, Prague, Poznan and Budapest as well as in the Leipzig Spring Fair.


The state-owned electrical engineering company VEM was launched on July 1st. It also includes VVB EM (Association of State-Owned Electrical Engineering Companies) companies outside of Dresden.


The AEG and SSW companies will be expropriated. The management staff is replaced or moves to West Germany. Extensive development and production documents disappear. Some of them serve as the basis for production for Sachsenwerk GmbH, which was founded in southern Germany.

On August 1st and 15th, respectively, the electronic factory Sachsenwerk Dresden-Niedersedlitz was built by the Soviet stock corporation “Kabel” under the direction of the Soviet general director S. A. Fomenko.


The end of the war also had profound consequences for the Sachsenwerk. A lack of spare parts and high utilization have led to heavy wear and tear on the machinery. The companies of AEG and SSW (Siemens-Schuckert-Werke), including Sachsenwerk Licht- und Kraft AG, were heavily involved in war production, and the shareholders of the Central German electrical engineering companies were involved in the armaments business. That's why there will be extensive dismantling this year and the following year. The number of employees, production and sales decrease significantly.

410 Saxon workers lost their lives in the Second World War.


In the 1930s, the first “standard motor series” (low-voltage asynchronous motors) was born at the Sachsenwerk as an epoch-making design and technology.


This year begins the development and construction of tram engines for the legendary Dresden “Großer Hechtwagen”, which was in use from 1931 to 1972 and which is followed by the “Kleine Hechtwagen” (used 1936 – 1972). With its typical shape it determines the streetscape of Dresden.


With the start of the production of radio receivers, the starting signal was given for a decades-long branch of secondary production.


The product range in the 1920s was dominated by direct current machines, three-phase machines and compensated three-phase motors. The equipment of the first pumped storage and dam works in Dresden with hydroelectric generators includes horizontal and vertical versions.


75 Saxon workers die in the First World War.


The product range was dominated by orders from the Ministry of War and Navy during the First World War (1#914 - 1#918).


Ten years after it was founded, Sachsenwerk Licht- und Kraft-AG has already manufactured 50,000 machines.


Sachsenwerk is one of the first German companies to organize its own apprentice training.


On March 3rd, the foundation stone for the history of the Sachsenwerk was laid with the conclusion of the partnership agreement for the “Sachsenwerk, Licht- und Kraft- Aktiengesellschaft with its headquarters in Dresden”. The company will be entered into the commercial register on April 29th.



VEM motors GmbH - Werk Wernigerode

VEM motors GmbH, based in Wernigerode, is one of the most important manufacturers of low-voltage motors in Germany. The Wernigerode VEM location supplies standard and standard motors as well as special motors in the power range from 7.5 kW to 1000 kW.

When developing quality products, challenging aspects such as energy saving and environmentally friendly production are consistently taken into account. The focus is on efficient drive solutions for all industrial applications. The development of energy-saving motors in efficiency classes IE2 and IE3 is very important. Our modern production, high quality standards and our special know-how ensure fast and reliable delivery of high-quality products.

Low-voltage machines and compact solutions are characterized by extraordinary operational reliability, long service life, effectiveness and environmental friendliness thanks to high motor efficiencies. Due to their great ability to be modified, these motors and drives can be used universally and continually open up new areas of application, be it in metallurgy, the chemical industry or in conveyor and transport technology.


History VEM motors GmbH Wernigerode


Manufacture and introduction of energy-efficient motors in classes IE1 (Standard Efficiency), IE2 (High Efficiency) and IE3 (Premium Efficiency)


Manufacture and delivery of synchronous motors with permanent magnet excitation.


Start of planning and expansion of capacities for aluminum die casting, modernization of the test facility for the production of modern energy-saving motors.


Company anniversary. Electric motors have been produced at the VEM motors GmbH site in Wernigerode for 60 years.

2006 -1999

Acquisition of previous VEM representatives and restructuring into sales companies in Sweden, Austria, Great Britain and Singapore.

16.5 million euros were invested in modern production equipment.


VEM motors Thurm GmbH is founded as an independent company and at the same time part of the VEM Group.


On the 50th anniversary and almost exactly on the day, the privatization by the entrepreneurial family Dr. Adolf Merckle from Blaubeuren.


Company name changed to VEM motors GmbH.


As a company of VEM Antriebstechnik AG, VEB Elektromotorenwerk Wernigerode is renamed VEM Elektromotorenwerk Wernigerode GmbH. Start of restructuring and concentration of production capacities for one of the most modern European production facilities for electric motors.


3,260 employees produce 350,000 engines per year on a total area of ​​58,000 square meters.


The company is expanding its production capacities with the construction of a new production hall.


Independent operation of the electrical engineering combine.


In order to save copper, Wernigerode engineers developed a motor with aluminum winding together with scientists from Hettstedt in 1950/51. This requires new insulation. The Wernigerode mechanical engineers solve the problem with a new type of insulation made from “Isoperlon lacquer”. However, the poorer conductivity of aluminum must be compensated for by lengthening the laminated cores. The factory produced these engines exclusively for the GDR's own needs until the early 1960s.


The Wernigerode electric motor plant is incorporated into VVB Elektromaschinenbau.


The Wernigerode electric motor factory was founded in January 1947 and began producing electric motors. 200 employees manufactured 200 engines in the year it was founded.
The factory was built on the site of the Rautal-Werke, which had supplied aluminum castings for the aircraft industry from 1938 and was dismantled after 1945.



VEM motors GmbH - Werk Zwickau

VEM motors GmbH - Zwickau plant has developed over a hundred years from a manufacturer of standard motors to a supplier of special and special drives. Within the VEM group of companies, the Zwickau factory specializes in motors with a power range of 0.06 to 9.0 kW and shaft heights of 56 to 132 mm.

High flexibility, from design to manufacturing and assembly to logistics, characterizes the Zwickau VEM location. Qualified specialists and a willingness to innovate ensure customers receive sophisticated new solutions and possible applications in this range of services. The focus is on the development of engines taking modern manufacturing technologies into account in order to use existing resources economically and efficiently. When developing products and systems, the plant relies on energy-efficient drive solutions that ensure the economical operation of systems.


History VEM motors GmbH Zwickau

2024 /

In An ambitious team with a high level of company and product identification works at VEM motors GmbH - Zwickau plant. In the summer of 2023 we celebrated our 115th birthday. Our 250 employees passionately develop and produce sophisticated electric drives, with high quality requirements, in many variants. Diversity and changeability have been our strength since the early years. With our over 100 years of experience, we always find it Our customers can rely on solutions for almost every application in the years to come! We have a new range of Ex engines in our range. With the new development in the ignition protection type of flameproof enclosure “db (eb)”, the traditional VEM company is proving its extraordinary experience in the engine business and its high quality standards. The sophisticated engine series is certified by IBExU and is built on site.


Both low-voltage production sites in Wernigerode and Zwickau will be brought together under the name VEM motors GmbH.


The Merckle family of entrepreneurs has sold the shares they acquired in 1997 to a Chinese family investor. The Wang entrepreneurial family takes over VEM as a group. In the same year, IE5 synchronous reluctance motors also began. They are used in highly efficient pump systems.


A new type testing facility with five test benches begins work and thus significantly improves testing accuracy. With the check of engines from the Explosion Protection II 2G Exe II T3 series, suitable for use in explosive environments, the new test facility has passed its first test.


The series of permanent magnet synchronous motors, as an efficient solution for variable speed motors, starts as series production. The motor series is operated exclusively on the frequency converter.

2005 /

The company is expanding two production halls by a total of 3,500 m². Production machines will be reorganized and the interim storage facility with subsequent shipping department will be redesigned.


A new generation of compact drives comes onto the market, which booms extraordinarily in the following years. In the same year, a special series with aluminum housings was introduced. The motor types are continuously sold to well-known machine manufacturers for special applications.


Becoming independent as VEM motors Thurm GmbH


The Blaubeuren entrepreneurial family Dr. Adolf Merckle buys the VEM companies from the Treuhandanstalt.


Due to the winding down of the GDR planned economy and the introduction of market economy principles, the electrical engineering company also shrank enormously. The Kombinat is ultimately dissolved and subordinated to VEM Antriebstechnik AG as VEM Elektromotorenwerke Thurm GmbH. During this time, the plant relocated all production capacities to the Zwickau-Pöhlau location and concentrated exclusively on the engine business. Shortly afterwards, VEM motors GmbH was founded, into which the VEM Elektromotorenwerke Thurm plant was also incorporated.


A very highly developed basic series of the standard KMR engine series is introduced. She received the GDR National Prize for Science and Technology and several international awards. The series doesn't catch on. The only buyers were the GDR and the Soviet Union. A year later, a new KMER standard motor series was introduced with international standards according to IEC, TGL and DIN.


As an independent factory, it will be incorporated into the electrical engineering combine. It is hoped that companies within an industry can work more effectively.

1967 /

The need for electric motors in small performance classes is huge. That's why the work is being expanded. Branch factories are built on a former mine site in Zwickau and a transmission factory in Schneeberg. The most important products now include geared motors, which western countries prefer to buy. The mine site in Zwickau is being expanded into a complete branch factory, with administration, winding department, stamping shop, mechanical production and assembly hall.


The KER series is being developed. Axle heights and power allocations correspond to DIN 42673. Fifteen years after the founding of the GDR, the 4,000,000th engine is delivered.


Like every company in the GDR, this company also had to make its contribution to supplying the population with consumer goods. Devices such as: do-it-yourself engines, garden shredders, motor hoes or laundry ironer drives begin to be produced.


You start with the development and standardization of a standard engine series. The aim is to reduce the size. Three years later, the development of the standard DMK motor series in 6 sizes was completed. The RGW countries adopt the IEC standard and a shaft height/power allocation is determined.


The company's designers are driving forward the standardization of electrical machines. The first generation of standard engines is produced. They start with the designations DA (three-phase motors with aluminum winding) or DH (three-phase motors with copper winding). From now on you can see the latest developments under the new logo at every spring fair in Leipzig.


After the war, industry in the Soviet occupation zone lost many businesses due to dismantling. The works of K&A Stephan were also included. They are transferred to Soviet property as reparations. A wave of ideologically motivated expropriations begins. Kurt and Alfred Stephan are also expropriated. The factories with the few remaining production machines become public property. Two years later the works were called VEB Elektromotorenwerke Thurm.


The enormous increase in demand for motors and geared motors requires the construction of a second factory. According to plans by Alfred Stephan, construction of a new, spacious factory began in 1938. Modern washrooms, showers and lounges, a workshop kitchen, dining room and a beautiful, large meeting room are also being considered, as are two ordination rooms for a company doctor. The very modern factory began production in 1940.


Fifteen years after the first engine designed by Alfred Stephan, the 100,000th engine is delivered. The product range is very diverse. Drives for forge fire blowers and machine tools, three-phase and single-phase motors, loom drives and even washing machines are on offer. A specially developed geared motor has also been available to order since the late 1920s. People abroad are starting to take an interest in the products. A distribution system is set up in numerous countries and an English manufacturer becomes a license manufacturer. The company is bursting at the seams with its many products.


In the newly built main factory, a two-story reinforced concrete building, spin dryers are now being manufactured with motors from K&A Stephan.


The brothers have gained experience in manufacturing electric fans and electric pumps in which they install Siemens motors. The orders continue to increase. You decide to set up your own electric and geared motor production. Alfred Stephan designs his first motor for a blower. From now on, motors from the company K&A Stephan will run in the machines of weaving mills. A new house with a large workshop is built and the entrepreneurs convert the company into a corporation.


The brothers Kurt and Alfred Stephan founded an electrical business on March 20th in Thurm, a town in the southwest of the Free State of Saxony, near Zwickau. Nobody suspected that in the next few years the company would develop into the largest industrial company in the town.
