Custom Laminated Rare Earth Neodymium Magnet Manufacturer

Laminated neodymium magnets are composed of multiple thin NdFeB slices bonded together with high-temperature insulating glue. Each slice is electrically isolated to block eddy current loops, specially designed for high-speed alternating magnetic field motors.

Solid monolithic magnets produce huge eddy currents and severe heat under high rotation speed, easy to suffer irreversible demagnetization. Laminated magnets cut eddy loss by 60% to 90%, much lower temperature rise, higher motor efficiency and longer service life. The only downside is higher processing cost.

Standard slice thickness range: 0.5mm ~ 3.0mm. Thinner slices bring better eddy suppression effect, but higher production difficulty and cost. We support customized thickness as customer requirements.

Our insulation glue layer is controlled within 20 and 30 microns, ultra-thin to avoid wasting magnetic space while maintaining stable insulation resistance.

No. We adopt high-pressure hot curing process with high shear strength insulating adhesive. After integrated outer circle precision grinding, the whole magnet assembly has excellent structural stability, no delamination under long-time high-speed operation and temperature cycling.
