Superior Strength Block Laminated Electric Motor Magnets Part No. HSLAMIM-31 – Laminated magnet is to cut the whole magnet into many small pieces of magnet, and then use specific glue to bond together. These small magnets are insulated from each other and enable to cut down electromagnetic eddy current.

Samarium Cobalt gives a higher attractive quality and temperature safety than either alnico or artistic magnets. Samarium cobalt magnets oppose temperatures up to 300 degrees C. They are to some degree weak and have low mechanical quality, however, they are a high vitality item. Search for Samarium Cobalt magnets in the high-end electric engines utilized for opening auto dashing and in addition to turbo hardware and voyaging wave tubes. They are additionally compelling for utilization in cryogenic provisions because of their wide temperature steadiness.
Neodymium Iron Boron magnets are much like samarium cobalt magnets yet might be oxidized all the more effortlessly. Because of the way that these magnets can without much of a stretch be consumed, producers frequently utilize a surface covering to counteract oxidation. They are additionally high-cost magnets however offer a reduced configuration. They don’t offer the mechanical quality of the other three sorts. These magnets offer high vitality processing and are found in mouthpieces, in-ear earphones and uproarious speakers and in addition guitar and bass pick-ups. These magnets are additionally usually utilized within workstation hard drives. Higher Strength Precision Superior Bonding Whole Laminated Magnet

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
