Claims (9)

1 - 5 : (canceled)

6 . An electric machine having a rotor and a stator comprising:

an internal wall facing the rotor, the stator including radial slots disposed circumferentially around the stator; and wherein the slots comprise a bottom wall separated from the internal wall of the stator to close the radial slots.

7 . Electric machine according to claim 6 , wherein the slots extend axially along the stator.

8 . An electric machine according to claim 6 , wherein the slots have an oblong cross section with the bottom wall being separated from the wall of the stator, a top wall and two faces connecting the walls.

9 . An electric machine according to claim 7 , wherein the slots have an oblong cross section with the bottom wall being separated from the wall of the stator, a top wall and two faces connecting the walls.

10 . An electric machine according to claim 6 , wherein the slots have a circular cross section.
