EMF waveform optimization using the permanent magnet volume-integration method
Bibliographic record
Abstract
The emf expression can be derived with the PM volume-integration method, allowing easier optimization and prediction of the emf harmonic content. An analytical expression is developed for predicting the electromotive force (emf) waveforms and flux linkage resulting from the motion of permanent magnets (PM) in the case of two cylinders, where the outer cylinder carries a surface-mounted winding and the inner cylinder carries the PMs. The expressions are based on the PM Volume-Integration Method, which uses a volume integral calculated over the magnet volume, rather than the usual surface integral over the coil surface. The specific case of surface-mounted arc PM with radial magnetization is analyzed. An outer cylinder with infinitely thin winding distribution on its inner surface is considered. The chording factor, slot factor and spread factor are included in the analytical expression. The emf waveform and related harmonics are predicted analytically and validated by comparing with a finite element analysis and with experiment.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
