Segmented permanent magnets |
| abstract |
A segmented magnet is disclosed comprising first and second layers of permanent magnetic material and an insulating layer therebetween. The insulating layer may include a rare earth element and a ceramic mixture including at least first and second ceramic materials. The ceramic materials may include a halogen and an alkaline earth metal, alkali metal, or a metal having a +3 or +4 oxidation state. The rare earth element may comprise up to 30 wt. % of the insulating layer. The segmented magnet may be formed by applying the insulating layer to a first sintered permanent magnet layer, stacking a second sintered permanent magnet layer in contact with the insulating layer and spaced from the first sintered permanent magnet layer, and heating the formed magnet stack. The heating step may include annealing the magnet stack at an annealing temperature within 100° C. of the melting point of the ceramic mixture. |
