Rotor for an electrodynamic machine

摘要

The rotor has a sheet body including sheet segments arranged behind each other. One- and two-legged distance bars are supported at a bolt for absorption of centrifugal forces. The bars include a broadened, radial inner section (7) and two outer sections (8) outwardly pointing in a radial direction in form of a radial leg (9). The inner section includes a bolt hole for penetration of an axial bolt. The leg of the bars includes a groove-like opening (11), a comb-like opening and passage holes for a cooling medium in a radial inner region (10) and a reduced material thickness region of the leg.
