Key Issues in Design and Manufacture of Magnetic-Geared Dual-Rotor Motor for Hybrid Vehicles
Bibliographic record
Abstract
This paper presents a practical design guide for the magnetic-geared dual-rotor motor (MGDRM), which is one of the candidates of the power split device in hybrid electric vehicles. The spoke-type permanent magnet rotor and simplified complementary structure are first used to form a new MGDRM, which exhibits less flux leakage, less cost, and less torque ripple. Based on this structure, an FEA aided key dimensions design technique, considering the height of the outer rotor, is developed with the goal of generating maximum torque for a given motor volume. The method also takes the core saturation into consideration. Moreover, to enhance the manufacturability of the complimentary MGDRM, a unique technique is proposed to implement the dual rotor structure with simple components. A prototype of 16 kW is designed and manufactured. Experiments are carried out on a hybrid powertrain test bench, verifying the proposed design and manufacture technique.

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.
