The invention discloses a self-staring motor rotor, a self-starting permanent magnet motor and a household electric appliance. The self-staring motor rotor comprises a first rotor core, a second rotor core, a squirrel cage, magnetic steel and a pressing plate, wherein the middle part of the first rotor core is provided with a first magnetic steel groove; the edge of the first rotor core is provided with a squirrel cage groove; the second rotor core is arranged at one end of the first rotor core; the second rotor core is provided with a second magnetic steel groove which is communicated with the first magnetic steel groove; the squirrel cage is positioned in the squirrel cage groove; the magnetic steel is arranged in the first magnetic steel groove and the second magnetic steel groove; the pressing plate is matched with one end, which is far away from the first rotor core, of the second rotor core. In the technical scheme, fitting is realized through the shapes and structures of the pressing plate and the second rotor core, and the mounting efficiencies of the pressing plate and the second rotor core are increased, so that the mounting efficiency of the self-starting motor rotor is increased.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a self-starting motor rotor, a self-starting permanent magnet motor and household appliances. Background technique [0002] At present, most self-starting permanent magnet synchronous motors adopt a squirrel-cage structure, which uses squirrel-cage windings to realize self-starting. However, in the squirrel-cage self-starting permanent magnet synchronous motor, the axial fixing of the magnetic steel requires axial rivet connection of the pressure plates at both ends, which makes the axial fixing of the magnetic steel very inconvenient. Contents of the invention [0003] The main purpose of the present invention is to provide a self-starting motor rotor, which aims to improve the convenience of axially fixing the magnetic steel. [0004] In order to achieve the above object, the self-starting motor rotor proposed by the present invention includes: [0005] The first rotor core ...
