    Abstract: An explosion proof motor, pump system, and method is provided comprising a motor housing having a circular first end spaced by a cylindrical wall to a circular second end and a cavity formed therebetween within the cylindrical wall. The circular second end formed by a bell wall. The cylindrical first end and circular second end sharing a longitudinal axis that extends concentrically from the first and second ends. A pump housing having a cavity for nesting for rotational movement a rotor comprising a plurality of blades and vanes. The rotor couples to a motor shaft of the motor during use. The cavity is further formed by the cylindrical wall wherein the cylindrical wall has an inner surface and an outer surface such that the outer surface runs parallel longitudinally about the longitudinal axis and the inner surface runs transversely about the longitudinal axis.

    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.
