description The utility model relates to a rotor structure of a large-torque submersible permanent magnet motor, a rotating shaft adopts a three-section shaft, a rotor core section shaft is a hollow shaft, and two ends of the hollow shaft are solid flange shafts; a rotor support is sleeved on a hollow shaft of the rotating shaft, a magnetic pole is fixed on the outer circle of the rotor support through a magnetic pole pressing strip, the magnetic pole is formed by installing a permanent magnet on a magnetic pole iron core, and two axial sides of the magnetic pole are fixed by magnetic pole pressing plates to prevent axial displacement. The magnetic pole pressing plates are fixed at two ends of the rotor support. The installation and replacement of the magnetic poles can be facilitated by adopting a sectional type magnetic pole and external pressing strip installation mode; the bread-shaped permanent magnet structure which is not concentric with the rotating shaft is adopted, so that air gap flux density harmonic waves ca
