摘要： The device comprises an annular guide component (1) that defines a central space (5) for accommodating the toroidal magnetic core (4) and comprises a plurality of channels (2) for receiving parts of a wire that form turns (3) of said toroidal coil upon arrangement about the toroidal magnetic core (4), said channels (2) being arranged transversely, from end face to end face of the annular guide component (1), distributed over an interior annular wall (1i) and separated from one another in accordance with a predetermined order. The method comprises use of the device of the invention for forming a toroidal coil comprising one or more windings.

摘要： The present invention relates to an inductor device, a method of manufacturing same and antenna. The proposed inductor device comprising a magnetic core (1), an electrically insulating support (10) with a cavity (11) arranged around said magnetic core (1), and three windings (DX, DY, DZ) of conductive wire arranged orthogonal to one another, wherein said electrically insulating support (10) is made of a single part and completely houses the magnetic core (1) which is accessible through an opening, the three windings (DX, DY, DZ) being supported on winding supporting faces (12X, 12Y and 12Z) of the electrically insulating support, confined between winding limiting edges (22) defined by lower corner protuberances (20) and centered with respect to the three orthogonal axes (X, Y, Z) such that said electrically insulating support (10) assures symmetry and orthogonality of said electromagnetic field vectors generated by the mentioned inductor device.
