Embodiment Construction
[0039] Figures 1a, 1b and 1c show the basic method of manufacturing a stator core 20 of an electrical machine manufactured according to the so-called lamination method. First, a substantially rectangular or cuboid-shaped strip 21 is provided, which has notches 22 . Both sides of these notches 22 are delimited by teeth 24 or half teeth 25 , respectively. The individual teeth 24 or half-tooths 25 are connected to each other via a yoke 26 . The yoke 26 extends substantially in the circumferential direction p and in the radial direction r, moreover it generally has a material thickness s which corresponds to the thickness of the lamination 21 . The yoke 26 has a yoke back 32 facing away from the tooth 24 or half-tooth 25 . The back face 32 of the yoke is oriented opposite to the direction r. The teeth 24 and the half-tooths 25 extend substantially in the radial direction r and in the circumferential direction p. The teeth 24 and half teeth 25 also have a material thickness s. ...
