Abstract
New structures of motor magnetic circuit can be realized by use of the soft magnetic composites (SMC). This paper presents new claw-pole motors with a polyphase winding and a standard cylindrical rotor which are using these isotropic materials. A division of the stator magnetic circuit in 3 parts and the use of a centralized winding with a small number of coils simplify the production process, the mechanical assembly and the winding realization. With these special stator geometries, the electromagnetic, mechanical and thermal functions are integrated in the same stator parts. This integration is much better than in a classical 2D structure using a laminated material. There is no end-winding and the copper volume can be minimized. The size of the additional parts which are necessary for the bearing housings and the mechanical fixation of the rotor are reduced. These structures can be equipped with an integrated cooling system, with efficient air convection or water circulation. This paper describes the design approach of these original structures. It demonstrates that such 3D structures can be derived from their equivalent 2D structures with a concentrated winding. The concept and the design approach are validated by the realization and the comparative experimental tests of two prototypes with a 3D and its equivalent 2D structure.

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.
