Numerical and Experimental Study of The Viscous Dissipation of Oil inside the Electric Motor’s Gap
Bibliographic record
Abstract
A numerical study has been carried out to quantify the level of viscous dissipation inside an electrical motor.The study has been performed using an in-house computational model.This paper presents the effect of several geometrical and operating parameters on the level of viscous dissipation generated within the stator-rotor gap.The geometrical parameters considered in this study are the gap size, rotor length and the stator inner diameter, varied in the range of 0.25-1.4mm, 140-1120 mm and 55-375 mm, respectively.The operating parameter considered in this study is the rotor rotational speed and oil level, which was varied in the range of 900-3600 rpm and 50-100 %, respectively.The numerical results have been validated using experimental data.Results indicated that the amount of heat generated due to viscous dissipation is directly proportional to the stator diameter and rotor rotational speed, and inversely proportional to the gap thickness.

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.
