Precision package: For small electric motors and stator segments
Small electric motors or small segmented electric motors require very precise electro sheet stacks. This allows for smaller tolerances and increases the engine’s performance, for example, via a smaller air gap. The stator and rotor packages can be machined mechanically.
Our expertise in precise electro sheet stacks
We also call small electro sheet stacks laminar precision parts. We are the ideal partner for small electric motors or the smallest stator segments because we master the required technologies with a great deal of expertise:
- Precise punching
- Accuracy over the entire life cycle
- Precise stacking
- Precise, firm baking
- and much more
Benefits of full-surface bonding
Full-surface bonding enables intricate shapes. You do not need to consider any connection points or weld seams.
FAQ – Looking for answers?
The smallest manufacturable stack is a single tooth for a stator with a diameter of 7 mm. The web width of this single tooth is 0.8 mm.
It is produced by punching in 9 lanes followed by baking.
At this size scale, neither bonding nor punch stacking can be applied reliably in the manufacturing process.
Backlack enables exceptionally high dimensional accuracy in precision lamination stacks.
It also provides excellent insulation between the individual laminations, resulting in a very rigid and stable electrical steel stack.
These properties simplify further processing and contribute to improved motor performance.
A electrical steel stack can do more than just fulfill electromagnetic tasks – especially when manufactured using backlack technology.
This bonding method produces particularly rigid and precise stacks, which can also be mechanically processed further.
For example, drill holes, threads, or fits can be easily integrated, enabling multiple functional uses of the core.
This opens up a wide range of applications where the electrical steel stack also takes on structural or assembly-related functions – with an entirely new level of precision.
