Multipole magnetized magnets, also known as multi-pole ring magnets, refer to the fact that there are multiple magnetic poles (NS) on one surface of the magnet, more than 2 poles. Generally, professional magnetizing coils are used for magnetization, and each coil is normally charged with one specification. Magnetic rings of different sizes are mostly used in motors, encoders, sensors and other fields.
Is the price of multipole magnetized magnets high?
The price of magnets mainly depends on the material, size, processing difficulty, and suppliers. The price of multi-pole magnetized magnets is expensive because of the mold and the cost of magnetizing fixtures. If you find a magnet supplier with suitable molds, you will save a lot of money.
What are the types of multipole magnets?
According to different materials, multipole magnetic rings can be divided into iron-iron-boron multi-pole magnetic rings, ferrite multi-pole magnetic rings, rubber magnetic multi-pole magnetic rings, which are more common.
Among the above several multi-pole magnetic ring materials, the strongest magnetic force is the multi-level magnetic ring of iron-iron-boron magnet material. Among the magnets, iron-iron-boron magnet is known as the "magnet king" and has a high remanence. In the multi-pole magnetic ring, the magnetic force of the same size and magnetic pole is also the strongest. It is mainly used in the fields of high-performance permanent magnet motors and sensors. In addition, according to different processes, the Ndfeb multipole magnetic ring is divided into sintered ndfeb multi-pole magnetic ring and bonded neodymium multipole ring magnet. The cost of rubber magnetic multipole rings and ferrite multipole rings is relatively low, but the magnetic force will be relatively weaker. At present, the most widely used products are circular magnetic grids, water pump motors, sweepers, etc.
As for the number of poles of the multi-pole magnetic ring, it is also different according to different customers, and it can be up to hundreds of magnetic poles. If you have a multi-pole magnetic ring quotation, inquiries, or inquiries, please contact us.
