Abstract

To make the slotted stator section (1) of an axial flux electric machine, a toroidal core (2), extending in a ring around a reference axis (20), comprises a central ring (21) in turn extending lengthways along the annular centre line (200) of the core (2) and defines a profile (210) transversal to the annular centre line of the core (2). At least one interruption (211) in the central ring (21) is used for fitting to the central ring both a plurality of toroidal coils (3), each by- means of its central through-hole (300) whose shape matches the transversal profile (210), and a plurality of toroidal elements (22) made of magnetic material, each by means of a respective central through-hole (220) whose shape matches the profile (210). Coils (3) and toroidal elements (22) are alternated and adjacent to each other along the annular centre line (200) of the core (2).
