Application: NdfeB Neodymium rare earth permanent magnets are widely applied in Auto, energy-efficient Motors and Generators, Machinery, Audio/Video and Communication Equipment, Medical Device(MRI), Office Automation, Magnetic Separator, etc.

Laminated magnet is produced with several pieces of magnets glued so as to reach insulation effect between those pieces. Therefore sometimes laminated magnet is also called insulated magnet or glued magnet. Laminated SmCo or laminated Neodymium rare earth magnets are proven to reduce the eddy current loss for the high efficiency motors.

In the permanent magnet synchronous motor, since the rotor rotates in synchronization with the stator, we offen ignore the eddy current loss in the rotor. In fact, stator slot effect, non-sinusoidal distribution of winding magnetic force and the harmonic magnetic potential generated by the harmonic currents in the coil winding will also cause eddy current loss in the permanent magnets of the rotor, the rotor yoke, and the metal sheath of the bundled permanent magnets. Block Laminated Motor Magnets for Eddy Current Loss
