Partzsch-Group

Thomas Partzsch

The Partzsch-Goup includes the companies Partzsch Elektromotoren, Partzsch Motoren (PAMO) Reparaturwerk GmbH, Partzsch Spezialdrähte, Partzsch Spezialwicklungen GmbH and Partzsch Windgeneratoren Service GmbH.

As a remarkable and medium-sized company, we are one of the biggest employers in the region of middle-saxony. Since almoust a half century, our products are taking a prominent place in different places in economy. Our innovative company is one of the best business for electric-motor-maintenance.

With an optimal customer base by offering high quality, adherence to delivery dates and management by walking around, we assure our success and business connexions.


Werner Partzsch

In the year 1954, the handicraft business PARTZSCH (a repair-business for electrical machines and systems) was founded by Werner Partzsch.Aligned as a regional business, the maintenance and repair of medium electrical engines and generators with power up to approx. 200kW was part of the business segment until 1989. On January the 1st 1989, Dipl.-Ing.Ing. Thomas Partzsch took over the business.

After the structural and social changes over the years 1989/90 in Germany, their was a chance for better developments and business expansion.

Now, "PARTZSCH - Elektromotoren" has been grown to a modern, medium-sized enterprise, which is known in foreign countries as well. The manufacture of different products (even with pending patents) meets satisfaction of our customer demands.

Continuing quality controls (like short-circuit tests as seen on left) are inherent

parts of the manufacturing process.

short circuit test

our machinery:•2 stripping and cutting machines•3 coil presses•1 coil bender (Spin Robot)

In a patent specification from the 19th of march 1912, Ludwig Roebel describes how to solve the problem of high temperatures in consequence of eddy currents in copper bars.

Based on this principle, we are manufacturing roebel bars with modern technologies. They fully comply with the highest standards of generators from the newest generation.

•1 laser cutting system,•2 cutting heads (synchronous)

•1 laser cutting system•with an integrated robot for loading and unloading

•1 measuring machine•1 punching machine

Accuracy is the key!We produce high-grade sheets and stator laminations with accuracies less then five-hundredth milimetre in consequence of continual quality controls and the employment of modern laser technology. High flexibility, machining speed, quality and the offering of a wide product and service range are top priorities.

state-of-the-art technology forlarge-scale productionResulting from our service and product range extension with regard to components used in the electric motor construction, this rotor and stator punching machine was put into operation. On its circular indexing table 4 sheets with an external diameter of 600 to 1250 mm can be punched in one run and with accuracies less then three-hundredth milimetre. Compared to the laser units,

punching machine from Müller Stanz- und Umformtechnikthis modern new-style technology offers more economic advantages especially for the large-scale production.
