Abstract
In this paper, the critical criteria for successful synchronization of line-start interior permanent magnet (IPM) motors are studied for different loading conditions. An approximate solution technique based on average torque analysis is developed for determining the critical slip and the critical inertia of a line-start IPM motor for steady state and dynamic high inertial loads. Transient analysis of a 1-hp three-phase four-pole line-start IPM motor is conducted to determine the accuracy of the proposed criteria. Experimental investigations are carried out for the same 1-hp laboratory IPM motor. Analytical, simulation, and test results are presented. There is close agreement between analytical, simulation, and experimental results, which validates the accuracy of the proposed criteria.

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
