<p>Al Ni Co and Ba ferrite magnets in switchable magnetic clutch tables. N6A. By using Ba-ferrite magnets in the fixed sections and Al, Ni, Co magnets in the movable parts with the poles oriented so that the fields from these 2 types of magnets add up when the table is on. Attraction is higher than in conventional tables, surface smoothness is better, switching action is light, giving very low wear of moving parts. Easily manufactured in all sizes, no particularly close tolerances required.</p> |
