Electrical machine having partially parallel slots and teeth

摘要

The present invention relates to a tubular body (100) for an electrical machine. The tubular body (100) comprises a curved surface area (101), a first tooth (110) and a second tooth (120). The tubular body (100) is arrangable with respect to a further tubular body (100) such that one of the tubular body (100) or the further tubular body (100) is rotatable with respect to the other one around a rotary axis (105). The first tooth (110) and the second tooth (120) extend from the curved surface area (101) along a radial direction (102) with respect to the rotary axis (105), wherein the first tooth (110) and the second tooth (120) are spaced apart from each other along a circumferential direction (103) around the rotary axis (105). The first tooth (110) comprises a first side wall (113) facing a second side wall (123) of the second tooth (120), wherein the first side wall (113) comprises a first section (111) which is parallel to the second side wall (123) such that a circumferential distance (104) between the first section (111) and the second side wall (123) is constant along the radial direction (102).
