Abstract

fetched live from OpenAlex

Synchronous motors (SMs) play an important role in various industrial applications due to their unique characteristics and advantages. One of the key advantages of a synchronous motor (SM) is its ability to operate at a constant speed, making them suitable for applications where precise speed control is required. SMs also have a high-power factor, which means they consume less reactive power. The excitation current of a SM is crucial for optimal motor performance and efficiency, as insufficient current can reduce speed and power output while excessive current can overheat the motor and reduce efficiency. Thus, it is essential to estimate the excitation current of a SM. Accurate estimation and control of the excitation current can be achieved through synchronous machine data modeling. The study showcases the estimation of the excitation current of a SM using regression-based approaches. In particular, the usage of Principal Component Analysis has generally improved the performance of the regression models. The best models belong to the family of Linear Regressors as highlighted in the results.

Not 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.
