We are the global pioneer of cutting-edge lamination stacks – from the idea to industrialization.

 

Our customers benefit from more freedom in design, materials and production. This will enable them to produce better electric motors with more power and less waste of resources. We think differently and industrialize the production of superior lamination stacks. Challenge and test us!

Technologies

Together with our customers, we develop solutions and feasibilities for better lamination stacks. In doing so, we use our decades of experience in the divisions of materials, processes, tools, machines and digital data.

Contacts

Depending on the requirements, different specialists from a wide range of disciplines are required. They are the basis for an optimal result. Successful collaboration based on partnership is based on trust and reliability – fundamental values that we live by. Let’s be successful on the market together!

New technologies need visionary ideas. SWD cooperates with universities and researchers as well as with specialists in the field of lamination stacks and electric motors. In doing so, we put our heads together and think holistically in terms of materials, tools, processes, machines, and digital data. Let’s pull in the same direction – from the laboratory to the industrialization of tomorrow!

Environment

For years, we at SWD have been playing our part in implementing the energy transition with various measures. We produce with reduced use of materials and are carbon neutral. We source all of our electricity from hydropower and from the solar panels installed on the buildings. All of the buildings are heated by heat pumps. Electric motors drive the future and we are helping to make them more environmentally friendly. This is our contribution to a sustainable future.
