Abstract
This article presents the design and optimization of a multiphase doubly excited generator (DEG) for wind turbine applications in a dc grid. The DEG has two rotors: 1) a wound field excited (WFe) rotor, which in principals is similar to a conventional synchronous generator (SG) and 2) a surface-mounted permanent magnet excited (PMe) rotor that has a similar operation as a PM generator. The DEG is connected to a multileg passive rectifier whose output is connected to a dc wind grid. The dual rotor topology allows modification of the output power and voltage of the DEG while eliminating the need for an active power electronic converter. The DEG is parametrized and undergone a multiobjective optimization solved by employing a differential evolution algorithm (DEA). The DEG output power, mass, and efficiency are optimized subject to a list of prescribed constraints. To verify the design procedures a small-scale DEG is built and tested in the laboratory, whose results are presented in this article.

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
