Complementary technologies cut costs
Coordinating the production chain with the component brings cost advantages. It is well known that a large proportion of the subsequent series production costs are incurred during the design of the component. In so far as possible, not only the component, but also the interfaces in the motor and in the process should be known and optimized.
Comprehensive professional expertise in complementary technologies
Our professional expertise in adjacent or integrable technologies is as strong as our core competence in producing lamination stacks. We improve the value chain or integrate additional functions into the component using complementary technologies, something which saves money.
Welding
We achieve the desired lamination stack quality thanks to our many years of experience in the welding of lamination stacks using the technologies TIG welding, plasma welding, and laser welding as well as the selection of the optimal welding method.
Precision shape hole
The precision shape hole is a connection technology between the shaft and the lamination stack. It does not require any expensive heating processes, but can be integrated into the existing punching and stacking process. SWD has already produced more than 1.5 million parts in series manufacturing.
Mechanical processing
Mechanical processing such as grinding, honing, milling, and drilling can be carried out thanks to the high level of stiffness and density of the lamination stacks. Downstream chemical processing to eliminate short circuits between the laminations is standard.
FAQ’s about complementary technologies
A precision shape bore is an ideal solution for joining the shaft into the electrical steel stack. The bore shape is executed in a special geometry and rotated layer by layer. The combination with the shaft creates a very strong connection. Additional manufacturing steps are eliminated and the joining can be done at room temperature.
Bonded (Backlack) lamination stacks are very stable. The incorporation of holes or threads is easily possible. We have also already implemented the winding of axial flux rotors onto hubs. Grinding or honing of lamination stacks is also possible to achieve even tighter tolerances or better heat transfer.
