A rotor for an electric motor that includes a main body on which a support surface is formed, to which a permanent magnet element is attached. The main body is partially surrounded by a joining sleeve having chamber walls. The chamber walls together with the support surfaces form a chamber in which the permanent magnet element is arranged. The joining sleeve fixes the position of the permanent magnet element in a radial direction on the main body and a locking element is molded onto the main body. The locking element closes the chamber fixing the position of the permanent magnet element in the axial direction on the main body.
