Abstract
Lookup table (LUT)-based modeling of electric machines using finite element analysis (FEA) is an accurate technique for high-fidelity real-time emulation of electric motors, however, the cost of a huge computational burden. To overcome this shortcoming and the need for expensive hardware for the motor emulation, an artificial neural network (ANN)-based modeling method is proposed and developed in this paper for a 22-kW permanent magnet synchronous machine (PMSM). The ANN-based machine model is trained using back-propagation algorithms and its weights are optimized for the given arbitrary input(s) to consider the non-linearities in a PMSM, which are supposed to be reflected in the LUTs implemented in the emulation system. A strong correlation with minimal error, after comparing the dq-axis currents and electromagnetic torques extracted from both the LUT-based model and proposed ANN-based model under various loading conditions, confirms the accuracy of the proposed computationally efficient ANN-based modeling method.

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 it
