Analysis of Two Design Topologies for Variable Flux Permanent Magnet Motors
Bibliographic record
Abstract
This work presents a comparative analysis between an AlNiCo (Non-rare-earth magnet) and a series-hybrid permanent magnet (PM) variable flux motor (VFM) which has both an AlNiCo and a rare-earth magnet. The AlNiCo VFM utilizes a spoke type rotor and specially positioned flux barriers. The series hybrid VFM (SHVFM) utilizes a standard V-shaped rotor with AlNiCo and rare-earth PMs. A detailed electromagnetic finite element (FE) analysis is presented and validated through a set of experiments for measuring the key characteristics of each machine. Due to the virtual remagnetization (VD) effects, the SHVFM offers improved de/remagnetization characteristics along with improved overall torque density. The findings reveal that the series-hybrid VFMs are subject to high risk of rare-earth PM demagnetization. In addition, the re/demagnetization performance is highly related to the residual flux density of the rare-earth PM in SHVFM.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
