1. A stator comprising:
a ring comprising:
teeth and slots that open radially outwards between said teeth, and
material bridges, each linking two adjacent teeth to a respective base on the side of the air-gap,
a yoke attached to the ring, and
windings placed in the slots of the ring,
at least some of the material bridges having at least one deformable zone that is a corrugation forming at least one groove on one of the sides of the material bridge and a projecting relief on the opposite side, wherein the projecting relief or reliefs extend into a recess in the bottom of the corresponding slot, the stator being configured such that the deformable zone is deformed during assembly of the yoke on the ring.
