Embodiment Construction

[0039] figure 1 A partial side view of an electric machine 1 according to the prior art is shown. The electric machine 1 includes a stator 2 . Furthermore, the electric machine includes a rotor 3 which is arranged in the stator 2 . An air gap 4 is formed between the stator 2 and the rotor 3 .

[0040] The stator 2 comprises a stator carrier 5 or a laminated core, in which a plurality of grooves N1 to N48 are introduced. In the present embodiment, the stator 2 comprises 48 grooves N1 to N48 , of which only the grooves N1 , N2 , N11 , N12 , N13 , N14 , N23 and N24 are presently shown. Each of the grooves N1 to N48 includes a groove base 6 which corresponds to the region of the respective groove N1 to N48 facing the rotor or air gap 4 . Furthermore, each of the grooves N1 to N48 includes a groove opening 7 , which lies opposite the groove bottom 6 . The corresponding grooves N1 to N48 extend along the radial direction r of the electric machine 1 or the stator 2 . Furthermor...
