1. A stator for a rotating electrical machine comprising a stator mass comprising teeth and notches between the teeth, each of the notches being at least partially closed on an air gap side of the stator, electrical conductors housed in the notches and being distributed in at least two layers, the electrical conductors forming a single fractional winding, for which a ratio q defined by q=Ne/(2pm) is written as an irreducible fraction z/n, z and n being two non-zero integers, n being different from 1, where Ne is the number of stator notches, m is the number of winding phases and p is the number of pairs of stator poles,
wherein at least some of the electrical conductors are in the form of pins, and
wherein the electrical conductors are electrically connected together in the stator, connections between the winding phases being made in the stator.
