Super-high-temperature-resistant submersible motor

The invention relates to the technical field of submersible motors, and provides a super-high-temperature-resistant submersible motor. The submersible motor comprises a submersible motor body, a waterwheel, a water pump and a heat-resistant waterproof cable; the submersible motor comprises a radiator and a radiating hose; the top end of the submersible motor body is connected with the water pumpthrough a flange; the water wheel is fixed at the tail end of a rotor shaft of the submersible motor body; the water wheel is arranged in an inner cavity filled with water in the water-filled submersible motor body; the top end of the rotor shaft is connected with a power input shaft of the water pump through a connecting shaft; the radiator comprises an inner pipe and an outer sleeve; and the outer sleeve is arranged on the outer wall of the inner pipe in a sleeving mode. According to the invention, the problems are solved that in the using process, the heat dissipation effect is poor, and the using cost of a waterpro
