The utility model discloses a kind of coaxial double-
paddle motors used on sea surface flying
buoy, including the motor group constructed by first motor, second motor, the first motor, second motor corresponding output shaft is coaxially reversely arranged, to drive two groups of propellers reversely rotating respectively, construct water or
underwater propulsion coaxial double-
paddle type drive structure, the rotor
assembly and magnetic steel surface of the first motor, second motor are all provided with the
corrosion-proof layer of
electroplated nickel, the
stator core surface of the first motor, second motor is all provided with the protective layer of vacuum plating film;The oil
injection port is opened on the oil injection inner cavity side wall corresponding to the motor group, and the oil
injection port is connected with oil
injection device by matched connecting pipeline.The utility model is by being provided with
corrosion-proof layer on the rotor
assembly and magnetic steel surface of each motor, and being provided with protective layer on
stator core surface, so that it is more resistant to
seawater corrosion relative to existing ordinary motor, and service life is more guaranteed.
