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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
