Electric drive motor, wet rotor pump and household appliance

An electric drive motor, comprising:

• a stator with at least one electrically-actuatable stator winding;
• a rotor rotatably mounted in a field of said stator winding and leaving free an annular gap;
• a motor shaft and a magnet carrier, said magnet carrier being arranged coaxially in relation to said motor shaft and having at least one permanent magnet arranged on an outer periphery of said magnet carrier;
• said motor shaft and said magnet carrier being integrally formed in one piece, with said motor shaft and said magnet carrier having characteristics of having been jointly produced from a single initial metal sheet formed into an integrally shaped rotor body;
• and
• said integrally shaped rotor body having a motor shaft section and a magnet carrier section;
• said integrally shaped rotor body having a connecting section at an axial end face of said integrally shaped rotor body integrally connecting said motor shaft section to said magnet carrier section;
• said magnet carrier section extending substantially coaxially to an axis of said motor shaft section from said connecting section, and said connecting section extending substantially perpendicular to an axis of said motor shaft section between said motor shaft section and said magnet carrier section;
• said integrally shaped rotor body having at least one end face side breakthrough on said connecting section;
• and
• said integrally shaped rotor body having at least one channel extending substantially radially at least partially between said motor shaft section and said magnet carrier section formed in said connecting section, said integrally shaped rotor body having a hole at a radial end of said at least one channel in said connecting section configured for fluid to overflow from an outside of the integral shaped rotor body into the inside of the hollow cylindrical magnet carrier section.
