MagFloor: a Universal Magnetic Levitation Platform for Flexible Manufacturing
Bibliographic record
Abstract
The magnetic levitation (maglev) technology supports contactless and frictionless operations using permanent-magnet movers and coil stators. The movers can be constructed using Halbach arrays (HAs) or disc magnets (DMs). The MagFloor platform equipped with a square coil array is developed to actuate both types of movers compatibly, covering a 1.8m-by-2.4m horizontal working area. The Lorentz force and torque (wrench) models between the magnet movers and copper-wired square coils are established using data-driven approaches. The implementation time cost of the wrench models for the HA and DM movers on the programmable logic controller (PLC) is 2.3 μs and 4.1 μs per mover-coil-pair, respectively. The mover poses are measured using an optical sensing system and controlled at 1 kHz. The HA mover has unlimited yaw angle rotations and a maximum 7.5mm air gap. The maximum air gap and roll and pitch range of the DM mover are 65mm and ±45°, respectively. The horizontal motion range for both movers is only limited by the platform geometry. The HA and DM movers verified on a small-scale platform will be studied on the proposed maglev platform (MLP). The horizontal operating range of the MLP is expandable using a modular design to a large scale for future research on flexible manufacturing applications.

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.
