The motor rotor comprises a rotor core, wherein the rotor core comprises: a first rotor lamination (4), end rings (3), and second rotor laminations (2). The first rotor lamination (4) is provided with filling grooves, rotor grooves (6) and a shaft hole (7). The filling grooves comprise second filling grooves (52) and first filling grooves (51). The second rotor laminations (2) are arranged between the end rings (3) and the first rotor lamination (4), and are provided with communication grooves (21) corresponding to the filling grooves in the first rotor lamination (4). The total cross-sectional area of the rotor grooves (6) in the first rotor lamination (4) that are located between edges of inner holes and outer circles of the second rotor laminations (2) is smaller than the total cross-sectional area of the rotor grooves (6) in the first rotor lamination (4).
Provided are an electric motor rotor and a self-starting synchronous reluctance electric motor thereof, and a compressor. The electric motor rotor comprises a rotor iron core which comprises a first rotor punching sheet (1), wherein the first rotor punching sheet (1) is provided with filling grooves and rotor grooves (2); the filling grooves comprise second filling grooves (32) and first filling grooves (31); a plurality of magnetic barrier layers are provided at intervals on the first rotor punching sheet (1) along a q-axis; the plurality of magnetic barrier layers comprise two outer magnetic barrier layers and a plurality of inner magnetic barrier layers located between the two outer magnetic barrier layers; the outer magnetic barrier layers comprise the first filling grooves (31); the inner magnetic barrier layers comprise the rotor grooves (2) and the second filling grooves (32) located at two ends of the rotor grooves (2); and in the same inner magnetic barrier layer, dividing ribs (5) are arranged between the second filling grooves (32) and the rotor grooves (2).
