MAGNETIC ASSEMBLY AND MAGNETIC RING STRUCTURE

WIPO Patent Application WO/2023/208253

A1

The present application provides a magnetic assembly and a magnetic ring structure having the magnetic assembly. The magnetic assembly comprises a first magnetic piece and a second magnetic piece. The first magnetic piece comprises a first magnetic part, a middle part, and a second magnetic part, which are sequentially arranged in the width direction of the first magnetic piece. The middle part comprises a first non-magnetic area, an accommodation area, and a second non-magnetic area, which are sequentially arranged in the length direction of the first magnetic piece. The second magnetic piece is arranged in the accommodation area. The present application fully utilizes the Halbach principle and logically arranges the magnet structure, so that a strong magnetic field is formed on one side of the magnetic assembly due to the convergence of the magnetic lines of force, and a weak magnetic field is formed on the other side of the due to fewer magnetic lines of force. A strongest magnetic field can be generated by means of a minimum number of magnets, thereby reducing the magnet production cost, and making the method suitable for various scenarios.
