Abstract

The invention relates to a molded part for a rotor or stator of an electric machine, which molded part extends concentrically about an axis and has a face plate and at least one retaining strand, which is arranged on the face plate, wherein the retaining strand has a contact surface at the end of the retaining strand facing the face plate. The invention further relates to a rotor or stator for an electric machine having the molded part. The invention further relates to a rotor or stator for an electric machine, comprising a main body, which extends concentrically about an axis, and which comprises a permanent magnet, which is arranged in a cavity of the main body, wherein a retaining means is arranged on the permanent magnet, which retaining means has a retaining strand and a face plate, on which the retaining strand is arranged and which extends perpendicularly to the axial direction, wherein the retaining means is at least partially made from a curable medium. The invention further relates to methods for fastening a permanent magnet in such a rotor or stator.
