Abstract (en)

[origin: WO2008037640A1] A stator in an electric motor comprises a stator part configured as a hollow body, the part comprising a receiving space for receiving a rotating armature. The walls of the stator part are made of a magnetically conductive material and carry a magnet. In the circumferential direction, the walls of the stator part have a varying wall thickness, which is tapered in the region of the magnet and is configured in a reinforced manner, at least in some sections, in the region outside of the magnet. The stator is designed to have at least two parts, comprising an interior and an exterior stator part, wherein at least one of the stator parts has a varying wall thickness in the circumferential direction.
