The invention discloses a self-starting motor rotor, a self-starting permanent magnet motor and a household appliance. The self-starting motor rotor comprises a first rotor core, second rotor cores, mouse cages, and magnetic steels. The middle part of the first rotor iron core is provided with first magnetic steel grooves, and the edge of the first rotor core is provided with mouse cage grooves. The second rotor cores are arranged at the sides of the first rotor core and comprise a plurality of magnetic conductive plates which are stacked. The magnetic conductive plates comprise magnetic conductive bars and a plurality of magnetic conductive units connected to the magnetic conductive bars. The plurality of magnetic conductive units are arranged along the length direction of the magnetic conductive bars. The magnetic conductive bars are bent to form a ring such that second magnetic steel grooves are formed between adjacent magnetic conductive units. The mouse cages are in the mouse cage grooves. The magnetic steels are in the first magnetic steel grooves and the second magnetic steel grooves. According to the technical scheme of the invention, since the second rotor cores can be spread, the spreading states of two rotor cores can be mutually complementary, thus the formation of waste materials is reduced, and the utilization ratio of the materials is raised.
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 shape and structure of the rotor core is complex, so that during the processing of the rotor core, the parts of the rotor core interact with each other, resulting in a low blanking utilization rate of raw materials. Contents of the invention [0003] The main purpose of the present invention is to provide a self-starting motor rotor, aiming at improving the utilization rate of the raw material of the rotor iron core. [0004] In order to achieve the above object, the self-starting motor rotor proposed by the present ...
