When the permanent magnet motor is running, the motor will generate harmonic and the magnets themselves will generated skin effect, these all will bring a lot of eddy current loss, and then the temperature of permanent magnet rises, which results in irreversible demagnetization and affects the safety and stability of motor operation. So, the design of laminated magnet assembly is able to cut down risk and loss, however to improve the efficiency of motor.

The eddy current simulation experiment of different piecemeal permanent magnets
Experiment: NdFeB N35UH magnet, dimensions: 20*160*5MM
Magnets are tested at different excitation frequencies in a non-piecewise and piecewise manner .

Testing results :
The eddy current loss of magnet decreases with the increase of magnet segments

Technical requirement:
1.The thickness of insulating layers is within 0.04mm.
2. In normal temperature, the bond strength of insulating layers can reach more than 50Mpa.
3. The maximum working temperature can reach 200 ℃.
4. The whole geometric tolerance is within 0.05mm.
5. These small magnets are insulated from each other.

Application scope:
Now aerospace, automotive, motorsport, and industrial markets are turning to laminated rare earth magnets, and are working to balance the tradeoff between power and heat. Rectangle Laminated Magnets for Synchronous BLDC Motor, Superior Strength Block Laminated Electric Motor Magnets

Features :
Reducing electromagnetic eddy current
Remaining the same magnetic properties with the whole magnet or ever superior
