A multi-pole magnetic ring is a ring magnet used in the field of electric motors. It refers to the fact that a magnet is filled with many magnetic poles, more than 2 magnetic poles. Usually, a professional magnetizer is used for magnetization. Each type of magnetizing coil is usually used in a magnetic ring.
According to different materials, multi-pole magnetic rings can be divided into neodymium iron boron multi-pole magnetic rings, ferrite multi-pole magnetic rings, rubber magnetic multi-pole magnetic rings and samarium cobalt multi-pole magnetic rings. The first three are more common.
Among the above-mentioned multi-pole magnetic ring materials, the strongest magnetic force is the multi-level magnetic ring made of neodymium iron boron magnetic material. Among these magnets, neodymium iron boron magnets have high remanence. In the multi-pole magnetic ring, the magnetic force of the same specification and the same magnetic pole is also the strongest. Mainly used for high-performance permanent magnet motors and sensors. In addition, according to different manufacturing processes, NdFeB multi-pole magnetic rings will be divided into sintered NdFeB and bonded NdFeB, depending on customer needs.
The cost of rubber magnetic multi-pole ring and ferrite multi-pole ring is relatively low, but the magnetic force will be relatively weak. At present, the most widely used products are magnetic grids, water pump motors, sweepers and so on.
The multi-pole magnetic ring made of samarium cobalt material is the most high-temperature resistant multi-pole magnetic ring. The maximum temperature of this material can reach 350 degrees, which is currently the best magnet used in high temperature environments.
As for the number of poles of a multi-pole magnetic ring, it varies according to different customers, and the maximum can be hundreds of magnetic poles. Multipole Ring Ndfeb Magnet is your good choice.
