The utility model discloses a large-scale motor for immersible pump with good heat radiation structure, this motor include casing, stator, rotor and rotor shaft, and stator fixed connection is in the inner chamber of casing, and rotor fixed connection is on the rotor shaft, and the rotor shaft passes through the bearing to be connected on the casing, and rotor and stator are relative, rotor and the stator casing cavity of resorption separating the casing casing epicoele that becomes to be located casing upper portion and be located the casing lower part, rotor and rotor shaft between be equipped with first ventiduct, first ventiduct intercommunication casing epicoele and casing cavity of resorption, still be equipped with the second ventiduct of intercommunication casing epicoele and casing cavity of resorption between casing epicoele and the casing cavity of resorption, said motor still includes axial fan, and axial fan fixed connection is on the rotor shaft. This structure motor has good heat dispersion, reduces the motor burnout accident because of the not good emergence of heat dispersion.
