Parameter Determination of PMSM using Coupled Electromagnetic and Thermal Model Incorporating Current Harmonics
Bibliographic record
Abstract
Motivation: Permanent magnet synchronous machines (PMSMs) are widely used for electric vehicle (EV) propulsion owing to its high performance capabilities over a wide operating range [1]. With advent in machine structure and inverter topologies, accurate parameter determination incorporating machine non-linearities and effects of time and space harmonics is of paramount significance for high-performance control and analysis. Although classical $dq -$axis modeling is widely incorporated: 1) it fails to incorporate the machine non-linearities such as magnetic saturation, cross-saturation and leakage effects; 2) the spatial harmonic contents caused by machine winding and structural configuration are not considered in inductances and flux linkage; and 3) the effects of operating temperature on parameter variation are neglected [2]; and 4) it requires information from experimental data or complex look-up tables for parameter determination. On the other hand, finite element analysis (FEA) is computationally extensive and modelling of time harmonics becomes complex. Thus, in this paper, a coupled electromagnetic and thermal model incorporating current harmonics for parameter determination is developed and validated for a fractional-slot distributed wound (FSDW) laboratory PMSM.

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.
