Abstract
A pump for a water-conducting appliance, the pump having an electric motor comprising: a rotor comprising a ferrite body with at least four magnetic poles, wherein the ferrite body has a lateral-circumferential magnetization; and a stator comprising a pole chain made of a stack of a plurality of straight transformer sheets and rounded to a circular configuration by bending the stacked transformer sheets, wherein the pole chain has a plurality of pole portions each comprising a pole tooth; and a plurality of winding cores attached to the respective pole teeth for accommodating coils of a three-phase winding comprising wires; wherein the wires of respective phases of the three-phase winding are routed spatially separated from each other and without mutual contact at an axial end surface of the pole chain between and along adjacent winding cores around the pole chain; and wherein the wires are supported and guided such that their positions relative to the pole chain are substantially maintained when the pole chain is rounded from its straight configuration to its circular configuration.
