It is mainly applied to high-performance permanent magnet motors and sensors and other fields. The number of poles of the multi-pole magnetic ring can be customized according to customer requirements, and the highest magnetization level can reach hundreds or even more. This kind of magnet is not only applied to motors and sensors, but also widely used in many fields such as automobiles, numerical control machine tools, household appliances, computers, robots, etc.
