Abstract
The present invention relates to a process for making a magnetic armature of divided structure of annular shape and provided with a concentric annular groove, comprising the steps of winding a filamentary magnetic material on an annular mandrel, impregnating said winding with a hardening material, then cutting said winding along the equatorial plane of said mandrel, after said material has hardened. The invention is more particularly applicable to the production of divided magnetic armatures, especially for magnetic bearings.
