Rotor structure of permanent magnet motor

The utility model discloses a permanent magnet motor rotor structure, comprising a rotating shaft; the rotor iron core is sleeved on the rotating shaft, and a plurality of magnetic steel mounting separation grooves which are arranged at intervals are uniformly formed in the rotor iron core; the plurality of magnetic steels are respectively embedded in the corresponding magnetic steel mounting separation grooves; a plurality of insulating division bars which are respectively embedded between two adjacent magnetic steels; and the magnetic steel tension sleeve is sleeved on the magnetic steel outer ring, and an adhesive layer is filled in a gap between the magnetic steel tension sleeve and the magnetic steel. According to the rotor structure of the permanent magnet motor, the magnetic steel can be fixed on the rotor iron core only through the magnetic steel tension band without strapping of a strapping tape, so that the processing cost of the motor is reduced, strapping is not needed, the rotor fixing process is
