Abstract
Brushless direct current (BLDC) motors with Hall sensors are widely used in various applications. Installation errors for Hall sensors may lead to inaccuracy regarding the commutation position, which can lower the motor efficiency. To improve the performance of the BLDC motors, this study presents a new combined commutation optimisation strategy for obtaining the ideal commutation position. The new strategy consists of two procedures: averaging the misaligned Hall signals and compensating for the averaged Hall signals. A mathematical relationship between the DC‐link current and overall deviation error was established, and a proportional‐integral controller was built to compensate the commutation position. Several experiments were conducted to verify the effectiveness of the new combined commutation optimisation strategy.

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
