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.
