In practical applications, selecting a magnet based solely on the maximum operating temperature often creates potential risks. This is because whether a magnet undergoes irreversible demagnetization depends not only on temperature but is also closely related to factors such as the operating point (load line),... ...More>>
As for the role of the magnets, their primary function is to provide a stable and powerful magnetic coupling force. The inner and outer rotors form a closed magnetic circuit via the magnets, enabling synchronous transmission without physical contact.... ...More>>
Some people wonder: How do the rotors in household circulation pumps, aquarium pumps, and car cooling pumps—which are constantly submerged in water—manage to keep their magnets intact? How is this achieved?... ...More>>
As explained above, you should now understand that magnetic poles are determined by the magnetization method, not by the countersink structure. Specific pole assignments (N or S on particular faces) can be discussed directly with the magnet manufacturer.... ...More>>
The above covers whether a 12-pole (6-pair) magnetic ring is sufficient for encoders. For speed detection, cost-controlled products, and space-constrained small equipment, 12 poles offer excellent cost-performance. However, for motion control systems demanding high precision and stability。... ...More>>
In summary, magnets capable of generating radial magnetic fields are not limited to any single material but are defined by the core characteristic of “radial magnetization.” Whether in the form of discs, rings, wedges, or irregularly shaped plastic-molded magnets, they can all generate radial magnetic fields in practical applications.... ...More>>
Neodymium magnets have the advantages of strong magnetic force and small size, but the material itself is brittle. When subjected to impact, drop, or assembly impact, it is easy to have missing corners, cracking, or even fragmentation. Is there any way to improve the impact resistance of neodymium magnets?... ...More>>
First, if magnets are installed with reversed polarity (N installed as S, or two adjacent poles both as N or S), the motor will almost certainly fail to start normally.... ...More>>
Many people notice that when using magnets, stacking several together seems to make them “stronger” than a single magnet. Is this true? Today, we'll explain the science behind this phenomenon and illustrate it with examples.... ...More>>
In summary, whether magnets need to be marked with N S depends mainly on the application. Two magnets used in pairs need to be distinguished, while single magnets used for adsorption applications do not need to be marked.... ...More>>
