Abstract (en)
[origin: WO2014079794A1] The invention relates to a rotor of an electric motor, comprising a laminated armature core (1), a shaft, magnets (3) arranged on the circumference of the laminated armature core (1), and a plastic overmold (4). The laminated armature core (1) has at least one associated channel (9) on the circumference of the laminated armature core for each magnet (3), wherein the channels (9) extend parallel to the shaft, and the laminated armature core (1) has radially oriented webs (8) on the circumference, wherein the webs (8) extend parallel to the shaft and a magnet (9) is arranged between each pair of webs (8), and the plastic overmold (4) encloses the laminated armature core (1) and the magnets (3) to such an extent that only the radial outer face of the magnets (3) is free of plastic (4).
