13. A stator comprising:
a radially interior ring, comprising:
teeth creating between them slots open radially toward the outside, and
bridges of material each connecting two adjacent teeth at their base on the side of the airgap and defining the bottom of the slot between these teeth, and
a radially exterior yoke attached to the ring,
windings placed in a distributed manner in the slots, with, per slot, at least a winding of a first phase and a winding of a second phase different than the first phase,
for each winding portion within a slot, at least two pieces of sheet-form insulation,
the two pieces of sheet-form insulation surrounding each of the winding portions, these winding portions being separated from each other within the slot by at least four thicknesses of sheet-form insulation, the pieces of sheet-form insulation for each winding portion being distinct from the pieces of sheet-form insulation for any other winding portion.
