Assembly of magnets using flux diversion techniques

Rare earth magnets like Nd-Fe-B (Neodeuim-Iron-Boron) have gained popularity in various rotational and linear actuators, because of higher flux density, compact, easy availability in various shapes, sizes and magnetization directions. This paper discusses the assembly procedure for making magnet rings using radially magnetized segmented arc magnet of N45 and N33H grades, and the mover assembly of a linear motor. The above assemblies have been successfully carried out by diversifying the flux through the least reluctance path using external magnetic materials like iron. A magnetostatic analysis has been carried out for better understanding and verification of the adapted procedure. In this paper, the simulation results for N45 grade Nd-Fe-B magnets have been highlighted.
