1. Inductive energy emitter/receiver for an inductive charger of an electric vehicle wherein said inductive energy emitter/receiver includes:
a planar-shaped magnetic core with two opposed main surfaces (S);
at least one planar conductive coil wound around an axis (A) perpendicular to the main surfaces (S) of the planar-shaped magnetic core, said planar conductive coil being overlapped to one of said main surfaces (S) of the magnetic core;
an inductor casing being attached to said planar-shaped magnetic core and said at least one planar conductive coil
wherein the planar-shaped magnetic core is a made of a plurality of elongated partial cores, radially arranged, around a central opening that overlaps another opening in the planar coil that is adjacent, wherein each of the flexible elongated partial cores is perpendicular to an overlapped section of the planar conductive coil,
each elongated partial core is flexible;
the inductor casing is a flexible inductor casing made of flexible polymer bonded soft magnetic material, filling interspaces between the flexible elongated partial cores, and
the flexible elongated partial cores are surrounded by the flexible inductor casing, creating in conjunction a planar-shaped magnetic core flexible in two orthogonal directions,
wherein the flexible inductor casing collaborates magnetically with the flexible elongated partial cores producing, in conjunction, an effect equivalent to the effect produced by a single monolithic magnetic core.
