Abstract: A stator for an electric machine having a plurality of radially extending teeth, supported by an outer annular yoke radial to the teeth, at least part of the teeth supporting a coil and the outer annular yoke having flutes of partially cylindrical shape opening towards the teeth, at least part of the teeth each having, at their end, on the side of the outer annular yoke, a protuberance of partially cylindrical shape, the protuberance being held in the flute by contact points so that at least one part of the teeth performs a relative movement having a degree of rotational and/or translational freedom relative to the annular yoke.

Abstract: The disclosure relates to a high-speed electric machine, having a speed higher than 20,000 rpm, including a rotor having 1 or 2 pairs of magnetized poles, and an enhanced stator which has an outer diameter that is larger than 18 millimeters and which has 3 or 6 straight teeth extending radially and borne by a one-piece peripheral annular collar. At least a portion of the teeth bear coils, and the teeth are rigidly connected to one another and together form a one-piece planar assembly. The coiled teeth have a rectangular cross-section of width I and of length L, with formula (I).
