ProFluxx GmbH is a privately owned design engineering company that specialises in electrical machines.

We are located in Ingolstadt, a town in the South German state of Bavaria. Our primary focus is synchronous machines in the range of 20kW to 20MW. We however also support other machine types like asynchronous machines, reluctance motors and other elements of rotating machines like rotor dynamics.

The core of our business is centered on productive partnerships with our customers. ProFluxx is able to lend expertise in state of the art development of new machines and optimisation of pre-existing designs. The scope of our involvement typically includes support from concept generation, design for manufacturing, prototype development and production release. Through modular design we carefully tailor an approach for both low and high volume products which match the end-user application design requirements while ensuring that the customers’ product quality and cost needs are fulfilled.

Using our experience with combustion engine manufacturers, it is ensured that the resultant products are in line with market demands for robustness e.g. for Grid Code compatibility.

With the implementation of thorough flow and thermal studies, we fulfill not only average temperature rise requirements but also ensure that hotspots are within acceptable bands.

ProFluxx is capable of developing products with market-leading efficiency at acceptable cost levels.
