Prototype building and production

All customer-specific components are designed, confidentially, under one roof.

Our prototype building and production department builds prototypes and small batches of all components, as well as entire systems for electrical drives and power electronics.

This also includes production and assembly of all mechanical components, such as rotors, stators, magnets, and windings, combined with stringent quality control checks after every step.

We have all the necessary measurement technologies for this purpose.

We also have extensive experience in the fields of bonding and molding technologies. For special materials, we also have, among other things, annealing furnaces, e.g. in an atmosphere with hydrogen.

Power electronics and controls are designed in-house and entirely by ourselves. The corresponding instruments for quality assurance are also available, including test benches for power modules and circuit boards.

Production of power electronics systems takes place in an assembly room, in line with ESD guidelines. For limited series production of mechanical and electronic components, we can supply our clients with up to 1,000 units per year.
