Effect of voltage sag duration on the air-gap magnetic flux patterns and peak electromagnetic torques in saturated synchronous motors
Bibliographic record
Abstract
In this paper, the effect of voltage sag duration on the analysis of the air-gap magnetic flux patterns and the largest post-sag peak electromagnetic torques in saturated synchronous motors is studied. Moreover, the effect of the saturation both in the direct and quadrature axes and of the cross-magnetizing phenomenon (the magnetic coupling between the direct and quadrature axes) on the magnetic flux patterns and post-sag peak electromagnetic torques is investigated. An analysis of the air-gap magnetic flux patterns and the largest post-sag peak electromagnetic torques is presented as affected by: (1) the sag duration, (2) the different saturation modellings, (3) the sudden phase shift of the air-gap magnetic flux just after the end of the sag, and (4) the change in the rotor speed (rate of change of the load angle) specially in the cases of relatively long sag durations.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
