About the Product
Neodymium arc magnets are built for rotor and stator prototypes, magnetic couplings, and curved
fixtures. The arc radius nests on hubs or housings so you can assemble partial or full rings to tune pole count and air gap. Magnetization is typically axial through thickness, with radial options for motor development. Tight arc angle, ID/OD, and thickness tolerances support repeatable fits and balance. Estimate attraction with the pull-force calculator, then review grade and temperature limits in the material data and select coatings that suit your test
environment.
