This invention relates to a stator for an axial flux electromagnetic machine, with the stator forming a ring (1) having two substantially circular faces (1a, 1b) connected by a thickness comprising windings (3) regularly distributed in the ring (1). Each winding (3) is carried by a unit portion (4) having a core (5) around which the winding (3) is wound. The unit portions (4) are arranged concentrically edge-to-edge with respect to one another and have securing means (12, 12a, 14) with a support member (6) which is part or not of a casing housing the ring (1) carried either by axial and lateral faces of each unit portion (4) edge-to-edge or by at least one upper or lower face of with each unit portion being part of a substantially circular face.
