Multi-physics Design Platform for a High Power Density Multi-phase IPM Traction Motor: Analysis and Simulation
Bibliographic record
Abstract
Design of a high-speed high-power density interior permanent magnet (IPM) motor can be challenging since it is constrained by various multi-physics couplings. Therefore, feasible solution that meets different multi-domain specifications is hardly attained through individual domain calculations only. This paper presents a parameterized two-way multi-physics couplings platform for an IPM motor with hairpin windings. It incorporates electromagnetic (EM) analysis, stress and fatigue analyses, thermal analysis with computational fluid dynamics (CFD), and noise-vibration-harshness (NVH) analysis. The temperature gradient is implemented for all couplings by using temperature/yield strength-dependent material properties. A case study for a 300 kW IPM motor with a maximum speed of 17,000 rpm is developed and its performance is optimized to meet different design requirements.

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.
