Abstract

fetched live from OpenAlex

The modeling of machine windings for steep-fronted surge propagation has been based on an assumption that the slot walls act as flux barriers at the frequencies of interest (1 to 10 MHz). The assumption is valid for a solid slot environment, because the magnetic flux cannot penetrate beyond the skin depth, delta , which is of the order of 10/sup -6/ m for the frequencies concerned. However, this is not the case for a laminated slot environment, which can allow magnetic flux penetration on steep-fronted surge propagation in large AC motor coils are examined. Experimental data are reported showing that solid-slot models cannot accurately replace the laminated environments. Maximum interturn voltages observed for the solid slot model are smaller (by a factor of about 2/3) than those for the laminated slot environment. The differences between solid and laminated environments is attributed to the effect of laminations, which can be approximately modeled using the concept of surface impedance.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
