High-temperature-resistant radial anisotropic magnetic ring

The utility model provides a high-temperature-resistant radial anisotropic magnetic ring, and belongs to the technical field of motor equipment. The magnetic ring comprises two inner magnetic rings and two outer magnetic rings, the polarities of magnetic poles on the outer sides of the inner magnetic rings and the inner sides of the outer magnetic rings are the same, each outer magnetic ring comprises two semicircular magnetic shoes, outer fixing structures used for fixing the inner magnetic rings and the outer magnetic rings are arranged at the two ends of a magnetic ring body, an inner fixing structure is further arranged at the joint of the two outer magnetic rings, and the inner fixing structures are connected with the outer magnetic rings. The outer side of the outer magnetic ring is coated with a heat insulation coating. The heat insulation coating coated on the outer side of the outer magnetic ring can isolate the influence of external high temperature on the magnetism of the magnetic ring, so that the
