Design and Optimization of a high torque in-wheel surface-mounted PM synchronous motor using concentrated winding
Bibliographic record
Abstract
This paper presents a specific design process of a high-torque direct-drive in-wheel permanent magnet synchronous machine (PMSM) using concentrated winding and grain oriented (GO) silicon steel teeth for a hybrid All-Terrain Vehicle (ATV) application. Mechanical specifications and constraints of an off-road application are first demystified. An analytical design model, considering magnet flux and an induction reaction correction factors, is developed and used to determine geometric dimensions of a radial flux machine topology with surface-mounted permanent magnets (PM) and external rotor. The model also takes into account losses in winding, magnets, stator and rotor yokes and teeth. Electrical parameters of the equivalent machine circuit are determined to adapt the machine to the imposed converter voltage. All critical machine models parameters are validated with finite element (FE) simulations. The analytical design model is used to perform an iterative optimization procedure. This model is corrected during the optimization process by using correction factors derived from 2D FE analysis. The optimization process and some critical design validations are presented.

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.
