High efficiency demands the best materials, and the laminated rare earth magnets are proven to reduce eddy current losses in high efficiency motors. Fewer eddy current losses means lower heat and greater efficiency.

Magnetic component product name: Multi-layer bonded magnetic Laminated Magnet

Product description:

Multi-adhesive magnetic sheet is divided into a plurality of blocks of the entire magnet, with a special high temperature resistant adhesive is processed into a specific shape after bonding. Since the maximum operating temperature of sintered NdFeB is 220 ° C, the higher the operating temperature and the lower the magnetic properties, the lower the conversion and power of the motor. The motor heat loss is mainly caused by the heat loss caused by the electromagnetic turbine, and the multi-piece bonding can reduce the electromagnetic eddy current.

Technical requirement:

1. Each piece of magnetic steel is insulated.
2. The thickness of the glue layer is controlled within 0.04 mm.
3. The total tolerance is controlled within 0.05mm.
4. The temperature resistance of the glue can reach 250 °C.
5. The adhesive strength of the glue can reach more than 50 MPa.

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.

Purpose:

To reduce magnetic eddy current loss

Calculation of eddy current losses with and without lamination are shown below:
