Rotor for an electric machine of a household appliance, the household appliance and method for producing a rotor for an electric machine of a household appliance

摘要

The invention relates to a rotor (6) for an electric machine (4) of a household appliance (1), with a plurality of permanent magnets (19), which in the peripheral direction (18) of the rotor (6) with alternating polarity are arranged and distributed in the tangential direction, are magnetized, and a laminated core of the rotor (19), which consists of a magnetically conductive material, is formed, wherein the laminated core of the rotor (19) a plurality of openings (17) extending in the axial direction of the rotor (6) and which extend in the circumferential direction (18) of the rotor (6) are arranged distributed at a distance from one another, whereby in the through openings (17) the permanent magnets (19) are arranged in such a way that a of the respective permanent magnets (19) of outgoing magnetic flux in the tangential direction of the rotor (6), wherein between adjacent passage openings (19) in each case a segment (20) of the rotor packet (19), which is provided for the concentration of the magnetic flux of the respective permanent magnets (19) in an air gap of the electric machine (4) is formed, and wherein the permanent magnets (19) in comparison to the laminated core of the rotor (19) in the axial direction of the rotor (6) have a greater extension.
