Abstract
A stator body for an axial-flux electric machine includes: a plate in the form of a ring centered on a longitudinal axis, the plate including an upper face and at least one upper relief projecting from the upper face; and teeth, at least one of which includes a lower relief, a first side of which has a shape complementary to that of a portion of the upper relief, the upper relief being interlocked with the lower relief. The body includes a locking element extending opposite the upper face of the plate and interposed between the tooth and the plate so as to immobilize the upper relief in the position interlocked with the lower relief, and blocking unit blocking the position of the locking element with respect to the plate.

A stator body for an axial-flux electric machine comprising:
- a ring-shaped plate centered on a longitudinal axis, the ring-shaped plate comprising an upper face and at least one upper relief projecting from the upper face;
- teeth at least one of which comprises a lower relief a first side of which has a shape complementary to that of a portion of the upper relief, the upper relief being interlocked with the lower relief;
- wherein the body comprises a locking element extending opposite the upper face of the ring-shaped plate and interposed between the tooth and the ring-shaped plate so as to immobilize the upper relief in an interlocked position with the lower relief and wherein the body comprises blocking means blocking the position of the locking element with respect to the ring-shaped plate,
- wherein the locking element comprises a notch in which the upper relief and the lower relief are located, the notch having a lateral edge forming, together with the lower relief and the upper relief, a dovetail assembly wherein the lower relief forms a tenon and wherein the lateral edge of the notch and the upper relief form a mortise.
