Its core design feature is the reserved countersunk hole (conical hole) at the top, which can be fixed with screws or bolts to make the surface of the Neodymium magnet flush with the installation plane, achieving a concealed and stable installation effect. This countersunk Neodymium magnet is widely used in industrial equipment, electronic appliances, automotive manufacturing, furniture design and other fields, and is an indispensable magnetic component in modern precision engineering.
Advantages of Horizon Magnetics Neodymium Countersunk Magnet：
1. High magnetic performance: Countersunk magnet uses high-performance Neodymium Iron Boron magnets, which have extremely high magnetic energy product and coercivity, providing strong adsorption and retention forces. The adsorption force of Neodymium rare earth magnet is more than 10 times that of Ferrite magnets, and it can easily adsorb thick heavy metal parts.
2. Countersunk hole design: The top of the Neodymium disc magnet is designed with a countersunk hole (i.e. tapered hole), which is easy to fix with screws or bolts, making it flush with the installation surface, avoiding protrusions, and ensuring flatness and aesthetics after installation. The common countersunk angle is 82 ° or 90 °, compatible with different screw specifications (such as M3, M4, M5, etc.).
3. Diversified sizes and shapes: Neodymium countersunk ring magnet can adjust the position of countersunk holes, magnetic strength, and coating type as needed, providing a variety of sizes and shapes to choose from, including circular, square, and rectangular, and even developing irregular structures.
4. Corrosion resistance: The surface of the countersunk rare earth magnet is treated with coatings (such as Nickel, Zinc, Epoxy resin, etc.) to enhance corrosion resistance and adapt to humid, acidic and alkaline environments.
5. Environmentally friendly materials: Neodymium magnet with countersunk hole is made of environmentally friendly materials that comply with environmental standards such as RoHS, making it suitable for industries with high environmental requirements.
6. Long lifespan: Due to its high magnetic properties and corrosion resistance, Neodymium countersunk magnet has a longer service life, reducing the frequency of replacement and maintenance.
7. Easy to install: The countersunk hole design allows the Neodymium magnet to be fixed with simple screws, making the installation process simple and fast, suitable for various automated or manual assembly scenarios.
Applications of Neodymium Countersunk Magnet：
1. Industrial automation and mechanical manufacturing: Neodymium countersunk magnet is used to fix fixtures, positioning devices, etc. in CNC machining and assembly lines to improve equipment accuracy and stability, and enhance machining precision.
2. Automotive industry: In automotive manufacturing, Neodymium countersunk magnet is used for components such as door locks, sensors, motors, etc. to ensure their secure installation and efficient operation.
3. Furniture industry: In furniture design, countersunk Neodymium magnet is commonly used for fixing components such as invisible door stops and cabinet doors, providing a beautiful and practical solution.
4. Construction industry: In the construction field, Neodymium countersunk magnet is used to fix metal frames and avoid exposed screws affecting the visual effect.
Precautions in Using Neodymium Countersunk Magnet：
1. Collision prevention: The Neodymium magnet material is relatively brittle, and violent collisions or drops should be avoided to avoid damaging the magnet.
2. Avoid high temperature environment: Neodymium Iron Boron magnets are prone to demagnetization in high temperature environments, so they should be avoided from use in environments beyond their operating temperature.
3. Stay away from electronic devices: Strong magnetic fields of countersunk rare earth magnet may interfere with electronic devices, so sensitive electronic devices should be kept away from them during use and storage.
4. Correct installation: During installation, ensure that the counterbore matches the screw or bolt to avoid damage or detachment of the countersunk magnet due to improper installation.
5. Correct selection: In the high precision scenarios (such as medical equipment, optical instruments) and long-term outdoor use, Neodymium countersunk magnets coated with Epoxy resin or NiCuNi is recommended to ensure magnetic stability and extend service life.
6. Regular inspection: In corrosive environments, it is recommended to check the integrity of the coating every six months and replace damaged rare earth Neodymium countersunk magnets in a timely manner.
Magnets for PMSM (permanent magnet synchronous motors), particularly sintered Neodymium magnets (NdFeB), are integral components that determine the performance, efficiency, and reliability of PMSM motors. Neodymium magnets are essential components in modern electric motors, providing the necessary magnetic fields for efficient and powerful operation.
