The PARTZSCH Group
Repair and maintenance
Professional repair and maintenance of generators
We service and repair your electric motors and generators, regardless of make and type, and are happy to visit you on site. After a detailed assessment, we decide to what extent the machines can be repaired or whether it is more economical to rebuild or manufacture a new one. In addition to preventive maintenance, our repair services for your generator also include dismantling, cleaning and drying, the re-impregnation of stator and rotor windings and the mechanical reconditioning of roller bearings. We also offer comprehensive electrical tests for generators to ensure maximum performance.
For many years, the PARTZSCH Group has stood for expertise in the overhaul and repair of generators. Our manufacturer-independent services ensure that your system is recommissioned quickly and efficiently.
By the way: Not only are we equipped with the most modern production machines, we also have access to our own sheet metal coil warehouse, in which 500 to 600 tons of dynamo sheets of various qualities are stored.

The PARTZSCH universal generator
With our specially developed universal generator for systems with a voltage range of 6.0 to 11 kV, we are setting new standards in the repair and maintenance of generators. This innovative solution for companies minimizes downtimes and reduces costs.
The universal generator from PARTZSCH offers a flexible solution that is ready for use within a very short time. It is compatible with various existing mechanical interfaces. While the customer's generator is being repaired or serviced, the universal generator takes over the power supply: quickly, reliably and cost-effectively.
Technical features of the universal generator
- Variable connection options: The main terminal box offers two winding variants for voltages from 6 kV to 11 kV.
- Flexible direction of rotation: The generator works both clockwise and anticlockwise - without any loss of performance.
- Adaptable coupling: Pre-designed adapters allow easy integration into existing systems.
- Optimized bearing technology: Slide bearings with flexible oil supply ensure smooth operation.
- Highly efficient cooling: The self-ventilated system with integrated fan cooling ensures reliable heat dissipation.
- Automatic voltage regulator (AVR): The voltage regulator keeps the nominal voltage constant and prevents voltage fluctuations.
