The high magnetic energy product characteristics of tile type magnets provide strong support for the magnetic output of miniaturized devices, allowing them to maintain strong magnetic force in a limited space. High magnetic energy product means that more magnetic energy can be stored and released per unit volume, which is crucial for small devices with extremely compact internal space. In traditional magnets, a larger volume is often required to achieve the same magnetic output, and miniaturized devices cannot accommodate such magnets and can only sacrifice part of the magnetic force. Tile type magnets with high magnetic energy product break this limitation. In the same or even smaller volume as traditional magnets, they can release stronger magnetic force to meet the magnetic force needs of small devices, allowing the device to reduce its size without reducing the performance of core functions.
This characteristic directly enhances the magnetic output effect of small devices by increasing magnetic density. Magnetic density refers to the magnetic force strength per unit area or volume. The magnetic domains inside the tile type magnet with high magnetic energy product are arranged more neatly, and the magnetic field strength distribution is more concentrated, making the magnetic force within its range more dense. For example, in a small motor, the tile type magnet is installed on the rotor. The high magnetic density can make the magnetic field and the stator winding produce a stronger interaction, improve the torque and speed of the motor, and the size of the motor does not need to be increased. This high-density magnetic output allows small devices to perform the same work with magnetic efficiency similar to that of large devices, avoiding insufficient power due to reduced size.
The high magnetic energy product characteristic makes the magnetic field of the tile type magnet more concentrated, reduces the ineffective loss of magnetic force, and indirectly enhances the effective output. In small devices, the internal components are compactly arranged. If the magnetic field of the magnet is too dispersed, it may cause unnecessary interference to the surrounding electronic components. At the same time, the dispersed magnetic force will also reduce the effect on the target object. The high magnetic energy product tile type magnet can focus its magnetic field more accurately on the area where it needs to act, reducing the spread of magnetic force in irrelevant directions. For example, in a small magnetically controlled valve, the magnetic force of the magnet can be concentrated on the valve core, ensuring that the valve core can be effectively driven within a small range of movement, which not only improves the response speed of the valve, but also avoids the interference of magnetic force diffusion on nearby sensors, making the magnetic output more targeted.
In the dynamic operation of miniaturized equipment, the high magnetic energy product characteristic helps maintain the stability of magnetic output. When the equipment is working, vibration, temperature changes, etc. may occur, and the magnetic force of traditional magnets is prone to fluctuations. The high magnetic energy product tile type magnet has stronger magnetic stability and can maintain the consistency of magnetic output in a dynamic environment. For example, in the magnetic transmission mechanism of small precision instruments, the magnet needs to continuously and stably transmit magnetic force to ensure the uniform speed operation of the mechanism. The high magnetic energy product characteristic prevents the magnet from experiencing a sudden drop in magnetic force when vibrating, ensuring a smooth transmission process and avoiding the decrease in equipment operation accuracy caused by magnetic force fluctuations, which indirectly ensures the effective use of magnetic output.
The arc structure of the tile type magnet is combined with the high magnetic energy product characteristic to further optimize the magnetic output direction in small equipment. The internal space of small equipment often presents irregular shapes, especially some arc-shaped or circular parts. It is difficult for traditional flat magnets to fit these parts perfectly during installation, resulting in a deviation between the magnetic output direction and the required direction, and part of the magnetic force is wasted due to angle problems. The arc design of the tile type magnet can fit closely with the arc parts of the equipment, so that the magnetic output direction is more in line with the working requirements of the equipment. Combined with the strong magnetic force brought by the high magnetic energy product, each magnetic energy can act on the target in the optimal direction, reducing the magnetic loss caused by directional deviation, and maximizing the use of limited magnetic force.
The high magnetic energy product characteristic reduces the dependence of small devices on the number of magnets, thereby simplifying the structure and enhancing the coordination of the overall magnetic output. In small devices that require multiple sets of magnets to work together, if magnets with low magnetic energy product are used, it is often necessary to increase the number to achieve the required total magnetic force, which will take up more space, and the mutual interference of the magnetic fields of multiple sets of magnets may cause the overall magnetic output to be unstable. Tile type magnets with high magnetic energy product only need a small number to meet the total magnetic force requirements, reducing the mutual interference between magnets and making the magnetic field distribution more uniform and coordinated. For example, in a small magnetic levitation device, a small number of tile type magnets with high magnetic energy product can form a stable levitation magnetic field, avoiding the instability of suspension caused by the mutual interference of multiple magnets, while saving internal space and making the device structure simpler.
This characteristic can also improve the energy efficiency of small devices, allowing magnetic output to be highly efficient with low energy consumption. Small devices are usually battery-powered and are sensitive to energy consumption. If the magnet needs to be supplemented with additional energy to maintain magnetic output, the power consumption of the device will increase. The tile type magnet with high magnetic energy product itself has strong permanent magnetic characteristics, and can maintain stable magnetic output without continuous power supply, reducing the energy consumption of the device in maintaining magnetic force. For example, in small portable magnetic tools, the magnet can maintain strong adsorption for a long time without frequent charging or power replacement, which not only prolongs the use time of the device, but also ensures the effectiveness of magnetic output during the entire use process, so that the energy efficiency of the device is improved.
In the research and development of miniaturized devices, the tile type magnet with high magnetic energy product provides greater flexibility for design, which indirectly promotes the optimization of magnetic output effect. Due to its small size and strong magnetic force, designers do not need to sacrifice other functions of the device in order to accommodate large magnets. They can lay out the internal structure more freely and install the magnet in the position that is most conducive to magnetic output. For example, in small medical devices, designers can integrate high magnetic energy product tile type magnets into narrow probes, allowing the probes to generate sufficient magnetic force to drive internal components when they penetrate deep into the human body to complete precise detection or treatment operations. This flexible design space allows the magnetic output to better adapt to the functional requirements of the device and achieve the best results.
