A Hybrid Coaxial Magnetic Gear Using Flux-Focusing Halbach Permanent Magnet Arrangement
Bibliographic record
Abstract
The interest in developing magnetic gears (MGs) has been considerably increased in recent years due to the numerous advantages such as high torque density, low maintenance and overload protection. In this paper, a new MG that integrates flux-focusing and Halbach configurations is proposed. The special design of the radially magnetized permanent magnets (PMs) at both edges of the inner rotor improves the magnetic field distribution and enables the proposed MG to be designed with a high torque density. Parameter sweep analysis is used to maximize the torque density of the proposed flux-focusing Halbach coaxial MG (FFH-CMG), and reduce the volume of PM material used in the design. Finally, the electromagnetic performance of the proposed FFH-CMG is investigated using both 2D and 3D finite element analysis (FEA). The results show that the proposed FFH-CMG can achieve the largest torque density when compared with its counterparts and maintain a low torque ripple.

How this classification was reachedexpand
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.
