Zusammenfassung:A casing (2) of a submersible electric motor used underwater which houses a reduction gear device (3) and an electric motor (4) is filled with an electrical insulation material (8) whose thermal conductivity is higher than that of air. The heat dissipation ability of the electric motor (4) can be improved by using the electrical insulating material (8) having a high thermal conductivity. Accordingly, the capacity of the coil of the motor (4) can be increased and the output power / volume ratio can be improved.
