Investigation of Phase Angle Displacements in Six-Phase PMSM with Concentrated Windings for Reduced MMF Harmonics
Bibliographic record
Abstract
Multiphase concentrated wound (CW) permanent magnet synchronous machines (PMSMs) have high content of space harmonics in the magneto-motive force (MMF) waveforms. These harmonics result in distorted voltage waveforms and cause additional losses thereby deteriorating the machine's performance. However, the magnitude of space harmonics in multi-phase machines is lesser when compared to three-phase CW PMSM. In order to eliminate and/or reduce space harmonics even further in the MMF waveforms, this paper investigates non-conventional phase angle displacements for a six-phase 36-slot/34-pole CW PMSM. The six-phase CW PMSM considered has two independent three-phase windings. Conventional six-phase CW PMSM have phase angle displacements of 60° (symmetrical configuration) or 30° (asymmetrical configuration) between the two-phase sets. Based on star of slots method, a number of possible phase shifts between the two sets of three phase windings are investigated for reduced MMF harmonics, improved demagnetization and other performance characteristics for the 36-slot/34-pole PMSM and are compared along with conventional phase displacement angles of 60° and 30°.

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.
