Measuring systems for cores of soft-magnetic stamped parts
Stamped Parts with a high specific punching edge length have a decrease of the magnetic characteristics.
The increase of the specific losses can be measured
- off-line in the laboratory or
- in-line after a punching machine in production
In the pictures a yoke is shown for the off-line investigation of packages from E-laminations. In the special case packages up to a length can be examined by 60mm. The hysteresis losses are determined.

Measuring tasks are investigations
- to the influence of punching on the hysteresis losses
- to the influence of a stress relieving anneal
