Abstract
An inductor for an electrical rotary machine having a hollow or solid cylindrical yoke with a side wall to which is attached at least one sintered magnet having a pole face disposed facing an armature. The magnet is attached to the yoke by an over-molding which coats at least the pole face with a composite over-molding material containing a ferromagnetic material dispersed in a solid non-magnetic binder.
