Sintered neodymium-iron-boron (NdFeB) magnetic rings, with their ultra-high magnetic energy product, have become one of the core choices in the field of magnetic materials in recent years. They are widely used in various fields such as electronics, new energy, and intelligent manufacturing. Some netizens have asked whether sintered NdFeB magnetic rings can be used in motors?
In motor design, sintered neodymium-iron-boron (NdFeB) magnetic rings can be utilized and exhibit significant advantages in terms of magnetic performance. Sintered NdFeB is a high-performance rare earth permanent magnet material, characterized by high remanence, high coercivity, and high energy product, which can significantly enhance the output torque and efficiency of motors. Therefore, in motors where high power density and volume are critical, the use of sintered NdFeB magnets with a full-ring structure is feasible.

However, from the perspective of practical engineering applications, sintered neodymium-iron-boron magnetic rings are not the mainstream choice. The main reasons lie in the difficulty of radial multipolar magnetization and the high cost. Therefore, in the production of large quantities of motors, directly using sintered magnetic steel in the form of a complete ring often lacks economic efficiency.
Therefore, it is more common in the industry to use segmented sintered neodymium magnets or bonded neodymium magnetic rings as substitutes for sintered neodymium-iron-boron rings.
The above is an introduction to whether sintered neodymium-iron-boron (NdFeB) magnetic rings can be used in motors. Scenarios that require extremely high magnetic performance, must adopt an integral ring structure, and are not sensitive to cost are more suitable for using sintered NdFeB magnetic rings. However, in most conventional motor applications, due to considerations of manufacturing feasibility and cost control, segmented magnetic steel or bonded magnetic ring solutions are usually preferred.
