COMPOSITE INDUCTOR FOR ELECTRIC ROTARY MACHINES COMPRISING SINTERED PERMANENT MAGNETS COATED WITH A FERROMAGNETIC BINDER

摘要

An inductor for an electric rotary machine comprising a hollow or solid cylindrical yoke (1) to one side wall of which is attached at least one magnet (2) having a pole face arranged facing an armature (6). The magnet (2) is attached to the yoke (1) by over-moulding to coat at least said pole face with a composite over-moulding material (4) including a ferromagnetic material dispersed within a solid non-magnetic binder.
