Is the encoder magnetic ring with 12 poles (6 pair poles) sufficient?

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>>

What type of magnet can generate radial magnetic field?

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>>

How to improve the impact resistance of neodymium magnets?

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>>

Is the magnetic field at the inner circle of the magnetic ring very weak?

Whether the magnetic field inside the inner circle of a magnetic ring is “very weak” cannot be generalized; it depends crucially on the specific magnetization method.... ...More>>

Can a brushless motor still work if its magnet has a misaligned N S pole?

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>>

Do Magnets Get Stronger When Stacked?

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>>

18mm Neodymium Magnets Gauss And Pull Force

The magnetic flux density of 18 mm neodymium magnets is mainly affected by their grade (such as N35, N42, N54) and volume. As the grade of the magnet increases, so does the magnetic flux density.... ...More>>

Why do some magnets need magnetic pole markings?

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>>

Why can't strong neodymium magnets be made too thin?

This is because neodymium magnet is a sintered material, which is hard and brittle like ceramic. Once the thickness becomes too thin (such as 0.3mm, 0.2mm, or even thinner), it is highly prone to chipping and cracking during processes like slicing, grinding, electroplating, and packaging, resulting in a significant drop in yield rate.... ...More>>
