Significance of rotor slots number on induction motor operation under broken bars
Bibliographic record
Abstract
This paper investigates the effect of the rotor slots (bars) number of a three phase squirrel cage induction motor on the motor performance under broken bar fault condition. Two motors have been investigated at full load condition in healthy bars, one broken bar and two broken bars operations. The first motor has 24 stator slots and is investigated with rotor slots 20, 29 and 32 and the second motor has 36 slots and is investigated with rotor slots 28 and 44. The above-mentioned rotor slots numbers have been selected based on manufacturer's database. The effect of rotor slots numbers on motor performance with broken bars fault has been observed by analyzing the stator current emerging frequency components, steady state copper losses, slip at full load and steady state bar currents. Recommendation for the safest stator and rotor slots combinations has been provided based on simulated key performance indicators.

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.
