Laminated Magnet | High Performance Motor’s Favoriate

Whats is Laminated Magnet?

Laminated magnets are composd of multiple individual permanent magnets bonded and insulated with glue. This magnet segmentation technology is to divide NdFeB or Sm2Co17 blocks into multiple pieces and laminate them with insulation glue between each another. After that, the laminated block is grounded into final shape.

This special motor magnet is developed primarily to bring down eddy current loss in electric machines that cause loss in efficiency because of heat generated in the magnetic circuit.

Laminated magnet is an ideal solution for those electric motor makers looking to improve motor efficiency by changing permanent magnet motor materials. The magnet lamination has been an increasing trend for tech companies in aerospace, motorsport, automotive, home appliance, etc.
