Outer rotor switched reluctance motor design for in-wheel drive of electric bus applications
Bibliographic record
Abstract
In this era of electrified transportation, switched reluctance motor (SRM) is emerging as a prospective replacement to traditional electric motors especially for large heavy duty vehicles such as the electric bus. This paper proposes the design and analysis of a novel outer rotor in-wheel SRM. The integration of the motor housing inside the wheel rim saves significant space and eliminates the need for additional mechanical parts used in the centralized drive. The developed concept of short flux path configuration in this research manuscript has shown additional important features compared to previous SRM designs and a substantial increase in efficiency is reported. The procedures of deriving the output power equation as a function of the motor dimensions and parameters are explained in detail. Comparative finite element analysis (FEA) has been performed between the developed machine and a commercially available conventional SRM to elicit the merits of the developed machine. The results obtained through FEA investigations show that there is a reduction of torque ripple and a considerable increase in motor efficiency.

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.
