Loss Analysis including Effect of Manufacturing Degradation Due to Punching (Analysis)

The function of degradation characteristics of magnetic properties and iron loss characteristics identified with the single sheet testing have been applied in an analysis model.
With the finite element model, the degraded region is split into multiple layers and degradation characteristics, according to the distance to the cross-section, will be applied.
The above may seem like it would be time-consuming manual work, but it is all done automatically by the software.
This has made it possible to make comparisons of the degraded and non-degraded case.
At the venue on the day of our session, we would like to present topics such as loss analysis and material modeling.

Comparison of Hysteresis loss density distribution
Hysteresis loss density along the cutting edge is larger than
the one of the case that the steel sheets are not punched.
