Abstract:
A laminated rotor core for a rotor of a permanently excited electric machine and to a method for producing same are provided. The laminated rotor core consists of a plurality of stacked lamination rings, each lamination ring consisting of a plurality of circular segments. Each circular segment has multiple receiving openings, which are arranged in a V-shaped manner relative to each other in pairs, for permanent magnets and multiple passages for respective fixing elements. The laminated rotor core is mounted on a holding disc using the fixing elements, which run in the passages of the laminated rotor core.
