The disclosure relates to a rotor for an electric motor, having a laminated rotor core which is rotatable about a rotation axis and has a first rotor lamination and a second rotor lamination, which is arranged axially next to the first motor lamination, and having a plurality of magnet cutouts in each of which magnets are arranged and secured. The disclosure further relates to an electric motor having a rotor and a method for reducing the unbalance of a rotor.

Rotor, electric motor and method for reducing the unbalance of a rotor

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.

Laminated rotor core for a rotor, and method for producing a laminated rotor core

A lamination ring for constructing a laminated rotor core for a rotor of an electric machine and a method for producing a laminated rotor core made of multiple lamination rings for a rotor is disclosed. The lamination ring has multiple receiving openings for permanent magnets, and multiple structural elements are arranged homogeneously in the lamination ring at the same distance to one another in the circumferential direction in a rotated manner by an offset angle relative to the axis of symmetry such that the arrangement of structural elements is not symmetrical relative to the axis of symmetry of the lamination ring.
