In high-precision motors and some special electromagnetic devices, a multipole and anisotropic magnetic field is needed to realize accurate torque control and efficient energy conversion, but the traditional magnetic ring cannot provide such magnetic field characteristics.

[0003] The existing multipole magnetic ring adopts a simple bonding or welding method to connect the magnetic pole blocks.

[0028] The splicing end 4 between the magnetic pole blocks one 1 and the magnetic pole blocks two 2 is in an irregular shape that can be spliced, and the irregular shape of the splicing end 4 increases the contact area between adjacent magnetic pole blocks, not only enhances the mechanical connection strength of the splicing part, but also effectively reduces the energy loss caused by magnetic field leakage.

In addition, the open structure of the annular protection piece 3 facilitates heat dissipation, which is conducive to the timely dissipation of heat generated by the magnetic ring during operation, and prevents the magnetic ring from being overheated and causing a decrease in magnetic performance.
