Rotor structure of asynchronous starting permanent magnet synchronous motor

The invention discloses an asynchronous starting permanent magnet synchronous motor rotor structure which comprises an iron core formed by rotor punching sheets (2), pull rod round holes (9) and heat dissipation ventilation holes (10) are reserved in the rotor punching sheets (2), pull rods (11) are installed in the pull rod round holes (9), conducting bar grooves (12) are evenly distributed in the peripheries of the rotor punching sheets (2), conducting bars (3) are inserted in the conducting bar grooves (12), and the conducting bars (3) are arranged in the conducting bar grooves (12). The rotor punching sheet (2) is provided with permanent magnets I (4) and permanent magnets II (5), the permanent magnets I (4) are distributed along the circumference, and the permanent magnets II (5) are arranged at an angle of 90 degrees; the rotor punching sheets (2) are mounted on the rotating shaft (1) through key fit; and end rings (6) are welded on two sides of the conducting bar (3). According to the structural scheme
