NdFeB magnets have found widespread application in the mini motors that power 3C (computer, communications, and consumer electronics) devices. This is primarily due to their unparalleled magnetic properties including high flux density, high resistance to demagnetization, and excellent temperature stability. As a result, NdFeB magnets offer significant advantages over traditional ceramic and AlNiCo magnets in miniaturized motors that require high torque-to-volume ratios. We will discuss the various shapes of NdFeB magnets used in motors for 3C devices and analyze the market trends in this space. We will also discuss the advantages of using NdFeB magnets over other materials and highlight the strengths of Zhejiang Zhongke Magnetic Industry Co., Ltd. in manufacturing these magnets.

Shapes of NdFeB Magnets used in 3C Devices
NdFeB magnets for use in 3C devices are typically available in several shapes including discs, cylinders, blocks, and rings. Each shape has unique advantages depending on the specific motor application. For example, disc-shaped magnets are ideal for applications where a flat, stable magnet surface is required for accurate positioning. Cylindrical magnets are commonly used in axial flux motors, where the magnet is magnetized along its axis and produces a radial magnetic field. Ring magnets have a hole in the center and are suitable for use in brushless DC motors, where the rotor is typically mounted on the shaft and rotates around the stator. Block-shaped magnets are versatile and used in a wide range of applications.

Advantages of Different Shapes of NdFeB Magnets
Disc-shaped NdFeB magnets have a high surface area-to-volume ratio, making them ideal for high-speed applications where the motor needs to dissipate heat quickly.
Cylindrical magnets, on the other hand, have a more uniform magnetic field distribution and are ideal for applications where the motor requires a high torque-to-volume ratio.
Ring magnets offer excellent radial strength, making them ideal for use in high-performance brushless DC motors.
Block-shaped magnets are versatile and can be used in various motor applications.
Market Trends for NdFeB Magnets in 3C Devices
Advantages of Zhejiang Zhongke Magnetic Industry Co.,Ltd. in Manufacturing NdFeB Magnets
Zhejiang Zhongke Magnetic Industry Co.,Ltd. has been a leading manufacturer of NdFeB magnets for more than 12 years. The company has invested heavily in research and development and has developed several proprietary technologies that enhance the performance of NdFeB magnets. Some of the advantages of Zhejiang Zhongke Magnetic Industry Co.,Ltd. in manufacturing NdFeB magnets including:
1. Advanced manufacturing processes: The company uses state-of-the-art manufacturing processes to produce high-quality NdFeB magnets that meet the demands of the 3C device market.
2. High-quality materials: Zhejiang Zhongke Magnetic Industry Co.,Ltd. uses only high-quality raw materials to produce its NdFeB magnets, ensuring that the magnets have excellent magnetic properties and are highly durable.
3. Customization: The company offers customized NdFeB magnets to meet the unique requirements of its customers.
4. Large-scale production: The company has a growing production capacity after the new factory bulit, which allows it to produce NdFeB magnets in large quantities, making it an ideal supplier for the high-volume 3C market.
NdFeB magnets have become an essential component in the mini motors that power 3C devices. The use of NdFeB magnets in 3C devices is expected to increase significantly in the coming years, driven by the increasing demand for high-performance motors that can operate in harsh environments. The different shapes of NdFeB magnets offer unique advantages depending on the specific motor application. Zhejiang Zhongke Magnetic Industry Co.,Ltd. has established itself as a leading manufacturer of NdFeB magnets, thanks to its advanced manufacturing processes, high-quality materials, and customizability.
Zhongke is committed to becoming a world-renowned supplier of permanent magnet material application solutions in the field of new generation consumer electronics and energy-saving home appliances.
The company's current production process of permanent ferrite magnets is as follows: the purchased pre-fired materials are mixed according to their own formula and ingredients, and after being ball milled by a ball mill, ferrite is produced through steps such as precipitation, wet pressing, sintering, and grinding. Body magnetic tiles, ferrite magnets and other finished products. The specific production process flow chart is as follows:
The strontium ferrite calcined material (the main component is SrFe12O19) is mixed with calcium carbonate, silicon dioxide, strontium carbonate, lanthanum oxide, cobalt oxide and other ingredients according to the formula ratio.
The raw materials are added with water and pulverized by a ball mill to form a slurry, which is placed in a sedimentation tower for precipitation.
The dehydrated material formed by precipitation is made into a green body through an automatic press in a normal air environment.
The raw body is sintered at high temperature into a mature body through a wet-pressed magnetic tile electric-fired roller kiln or a wet-pressed magnetic steel gas-fired roller kiln.
The cooked blank is processed by a fully automatic grinding machine processing line to form a finished product.
The magnetic properties, appearance, size and other indicators of the magnets are inspected, packed and put into storage.
The company has applied and improved a number of advanced technologies in the industry, such as high-performance ferrite slurry stabilization technology and secondary ball milling batching technology, which has solved the quantitative problem of material added in the preparation process. And we use double coupling dispersion and fine grinding to overcome the problems of slurry agglomeration and particle size distribution consistency. The performance of the slurry obtained in the ball milling process is more stable, which reduces the unit operating time of the ball milling equipment, improves product quality, and reduces production costs.
The company uses a unique new green release agent independently developed to prepare magnetic tiles. The new green release agent is an organic combination of microbial technology and surface release treatment technology, which can degrade oil molecules, reduce the oil content of the release agent, and restore the surface. active lipophilic factor. The product is combined with the surface release process, and the release effect of the magnetic tile is improved through a new release agent, and the surface finish of the blank is improved. The demoulding technology has the characteristics of simple preparation method and convenient application, and improves production efficiency.
By transforming the sintering preheating system equipment, the company reduces the water content of the sintered green body in the kiln, greatly reduces the waste rate caused by factors such as cracking and lack of oxygen during sintering, and improves the sintering density and mechanical strength of the product. Obtain good microstructure and magnet properties. The company has also realized the sintering base temperature that products with different performances can adapt to through formula adjustment. Products with different specifications, sizes and performances can be co-fired at the same temperature, which significantly improves the production efficiency of the sintering process. In addition, in terms of veneer loading and billet loading, the company has adopted a bulk stacking method that conforms to the company's product features of small shape and light weight after many tests, realizing heavy veneer loading, good sintering atmosphere, and high sintering yield. good effect.
By optimizing the parameters of grinding machines and other processing equipment and improving the process technology, the company has improved the consistency of product thickness to ≤0.02MM within L30MM and ≤0.04MM within L50MM, and has mastered the technology of three-phase motor magnets produced by grinding tooling. Breakthroughs have been made in technical difficulties in the industry, such as product precision and stable equipment performance, and certain innovations have been achieved in technology and equipment.
The company's magnetic tile products are developing in the direction of high efficiency, low consumables, and low energy consumption. For example, through atomic substitution and compound doping, the rare earth-free ZK-5B high-performance motor magnetic tile independently developed by the company reduces the coagulation of magnetic powder, improves the orientation effect, improves the material performance and reduces the production cost by using strong magnetic field to suppress and adding a double dispersant.
