Unlock Irregularly Shaped Magnets for New Industrial Applications
Irregular magnet, also known as shaped magnet, refers to the shape is different from the traditional round, square, bar and other regular shape of the magnet, which has a unique performance and application field, the following aspects are described:
1.Unique shape: there is no fixed geometry, can be customized according to actual needs, such as slot, step, semicircle, concave and convex, size head, T, bevel Angle, polygon and so on.
2.Complex magnetic field distribution: due to irregular shape, its magnetic field line distribution is more complex than that of regular-shaped magnets, and the magnetic field distribution is non-uniform, and the magnetic field strength and direction at different locations may be greatly different.
3. Diverse performance: through the selection of different materials, optimization design and processing technology, so that the shaped magnet has different magnetic properties, such as high coercivity, high remanence, high magnetic energy product, etc., to meet the requirements of various application scenarios on magnetic field strength, stability and so on.
4. Application specific: mainly used in some special occasions, can meet the functional needs of conventional shape magnets can not be achieved, in machinery, motors, motors, instruments, magnetic connectors and other industrial fields as well as medical, electronics and other industries have a wide range of applications.
5. Material selection: common production materials are NdFeb, ferrite, samarium cobalt and so on. Ndfeb magnets have very high magnetic energy product and coercivity, and can achieve a strong magnetic field in a small volume, but the temperature resistance and corrosion resistance are relatively poor; Ferrite magnets have low cost and good corrosion resistance, but their magnetic properties are relatively weak. Samarium cobalt magnets have excellent high temperature resistance and stable magnetic properties, but the price is higher.
6. Processing technology: Because the magnet material is more brittle, processing is more difficult, usually using grinding, wire cutting, EDM and other processes to change its shape, these processing methods can be processed into the required irregular shape without changing the original magnetism of the magnet.
7. Industrial field: in the motor, generator, shaped magnet can be used to produce a specific magnetic field, to achieve energy conversion and power output; In automation equipment and precision instruments, can be used for accurate positioning and control, such as servo motor, stepper motor magnet alignment and positioning, can achieve accurate Angle control and position feedback.
8. Medical field: For example, in magnetic resonance imaging (MRI) equipment, the use of shaped magnets can generate a strong and uniform magnetic field, which is used for imaging diagnosis of the internal structure of the human body, and help doctors detect diseases and lesions.
9. Electronic field: in some electronic products, such as mobile phones, tablets, etc., shaped magnets can be used for magnetic connectors, vibration motors and other components to achieve fast charging, vibration feedback and other functions; In addition, in audio equipment such as headphones and speakers, shaped magnets can also be used to enhance sound quality and sound effects.
10. Other fields: In the magnetic drive, magnetic suspension, magnetic braking and other systems, irregular shaped magnets such as ring shaped magnets can be used as core components, through the role of magnetic fields to transfer power, to achieve the suspension or braking of objects; In toys, crafts and other fields, shaped magnets can also be used to increase interest and creativity.
