Technical Field

[0001] The utility model relates to the technical field of multi-pole magnetic rings, and specifically relates to a multi-pole magnetic ring with high impact resistance. Background Technique

[0002] A multi-pole magnetic ring is an annular magnet widely used in the field of motors. It has multiple magnetic poles distributed on the circumference of the ring. This kind of magnetic ring can reduce the components of the motor, greatly reduce the assembly difficulty of the motor, and improve the reliability of the motor. The manufacturing of multi-pole magnetic rings usually uses professional magnetizing equipment for magnetization. According to different magnetization directions, these magnets can be further divided into axially multi-pole magnetized magnets and radially multi-pole magnetized magnets.

[0003] However, in the prior art, the multi-pole magnetic ring has poor impact resistance during use, thus reducing its service life.

[0004] Therefore, we propose a multi-pole magnetic ring with high impact resistance. Content of the Utility Model
