However, this method suffers from drawbacks such as high precision requirements for magnet manufacturing, difficult assembly, poor magnetic pole transition smoothness, and significant motor noise. Furthermore, this structure requires a soft magnetic material frame to fix the magnets, affecting assembly efficiency. Radiating magnetic rings are a type of specially oriented circular permanent magnet, magnetized radially along the circumference of the ring. They can replace assembled magnetic rings and are widely used in servo motors, magnetic drives, magnetic bearings, and sensors.
