Abstract
A rotor for a small electric motor (e.g., electric engine). The rotor having a rotor axis, multiple permanent magnets that are arranged in a spoke-shaped way as well as several inference cores. Each of the permanent magnets has two axial ends, two longitudinal sides, a radial outer side as well as a radial inner side. The inference cores protrude radially over the permanent magnets in relation to the rotor axis. The rotor is enclosed at least partially by a casting mold having multiple struts that extend in an axial direction and that overlap radially with the permanent magnets. The inference cores do not overlap with the permanent magnets on their radial outer sides, wherein both the permanent magnets as well as the inference cores are held together primarily directly by the casting mold in a radial direction.
