Synthesis of a Series-Hybrid Permanent-Magnet Variable Flux Motor
Bibliographic record
Abstract
This work focuses on synthesizing a series hybrid variable flux permanent magnet motor (SHVFPMM) from a single permanent magnet variable flux motor (VFM) and a rare-earth permanent magnet motor (PMM). Initially, the permanent magnet (PM) sizing process for the standard VFM is presented in terms of loading demagnetization, reversible demagnetization range, demagnetization/re-magnetization currents, average torque and torque ripple. Then, the PMM is investigated mainly in terms of average torque and torque ripple. The outcome of this analysis is then used as the starting point for designing the SHVFPMM. The PM proportions for the SHVFPMM is then analyzed. It is noted that there exists a limited range of PM proportions below which the variable flux PM is demagnetized under load condition and beyond which the torque density does not warrant the excessive increase in the de/remagnetization currents. For validating the proposed synthesis criteria, a 5 hp SHVFPMM is tested experimentally which lies within the derived PM design map.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
