Product Introduction And Advantages

With the development of artificial intelligence and automation technology, more and more precision-controlled electromechanical products are used. Miniaturization, light weight, and high efficiency are a trend of motors. Sintered NdFeB radiation magnetic ring is the first choice for making small high-energy motors. The key material has developed rapidly in recent years and is another new direction for the development of sintered NdFeB permanent magnet materials. However, the production process is more complicated and the current price is relatively high. At present, it is mainly used in high-performance permanent magnet motors and sensors. It has the advantages of high precision, stable operation and low noise. It is the first choice for high-speed and high-precision control motors. With the continuous maturity of technology, the price and performance will continue to meet most application fields. The sintered NdFeB multi-pole magnetic ring has the characteristics of a sine wave shape distribution of the surface magnetic curve.

The ultra-high surface magnetic field can greatly improve the efficiency of the motor. Without reducing the efficiency, the motor can be further reduced in weight, size and efficiency. The sintered neodymium iron boron multi-level radiating magnetic ring overcomes the disadvantages of splicing magnetic ring magnetic loss and difficulty in assembly, can replace the traditional tile-shaped block, and has high processing accuracy.

Our company is the only manufacturer in China that can make sintered radiation magnetic rings with a wall thickness of 1.5mm, and at the same time, the salt spray test can pass 96 hours without any changes on the surface of the product and does not rust.

Performance Parameters

Product Size And Inspection Tools

The product size is D15.6*D12.6*2.6mm.

The outer diameter of 15.6 and the inner diameter of 12.6 shall be inspected with specially made through stop gauges;

The thickness is measured with a micrometer;

The concentricity is required to reach ≤0.10, and the inner diameter micrometer is used to detect;

The thickness of the coating is required to reach 10-20uM and use a scanning electron microscope to detect it.

Demagnetization Curve

Watch Magnetic

The surface magnetism can reach more than 1300GS after saturation and magnetization.

Surface Treatment

The customer requires the salt spray to reach 96 hours without rusting. We have made repeated adjustments and trials to the process, and finally met customer needs, so that we have also reached a higher level in technology and developed higher performance products for the future Lay the foundation.

Quality Inspection

In order to detect whether the product meets the customer's needs, we usually pass some tests to check. For example: PCT test, salt spray test, aging test, tension test, etc.

QC Process Flow

Procurement of raw materials--- ingredients---smelting---cast inspection---hydrogen treatment---pulverizing---forming---isostatic pressing---sintering---blank---machining- --Plating---Finished Product Inspection---Packing---Delivery

Magnetic Direction

We often carry out 6-pole charging, 8-pole charging, 15-degree oblique charging, etc., and magnetization can also be carried out according to customer requirements.

Note: The magnetized product should be kept away from floppy disks, magnetic cards, magnetic tapes, credit cards, electronic equipment, electronic dashboards, cardiac pacemakers and other medical devices or similar objects.

Packing

Packaging: Standard air or sea packaging, such as: cartons, pallets, wooden boxes. If you want to transport goods by express or air freight, we will shield the magnetic field.

1. Pack every 30 pieces of qualified products into one piece.

2. Pack the rolled product in a small yellow box, each with 12 rolls and a box of 360 pieces.

3. A label is affixed to the small inner box.

4. One box for every 8 small boxes.

5. Sealing and packing.

[Delivery date and mode of transportation]

The sample delivery time is usually 7-15 days, and the mass production is about 15-30 days. The specific delivery time will be reconfirmed when the order is signed.

We have signed a long-term cooperation agreement with TNT/DHL/UPS/FedEx transportation company, and we will deliver the goods according to your needs.
