Abstract

Method for manufacturing a rotor assembly for an electric machine, in particular a permanent magnet synchronous machine, wherein the rotor assembly (1) has a rotor body (2) with at least two rotor lamination stacks (3, 4) which define magnet receiving spaces (5, 5') which are arranged circumferentially rotated relative to each other about the axis of rotation under a defined inclination, wherein potting material is introduced into at least one magnet receiving space (5, 5') of a first rotor lamination stack (3) in a first axial direction and potting material is introduced into at least one magnet receiving space (5, 5') of a second rotor lamination stack (4) in a second axial direction opposite to the first axial direction.
