Thruster for electric ship is a kind of installation on a ship 's, the device advanced for driving electric ship.Its mechanism of the thruster for electric ship of prior art generally comprises propeller main body and for driving the electric machine assembly of propeller main body, motor in electric machine assembly adopts the structure of internal rotor, external stator, namely rotor is arranged on centre, stator surrounding is in periphery, secondary on rotor, what stator was arranged is the coil producing alternating magnetic field, under this configuration, the generation of torsion is near center, and output torque is less.
Summary of the invention
In view of the defect of above-mentioned prior art, the purpose of this utility model is: provide a kind of high efficiency motor ship propeller, its motor has high output torque.
Technical solution of the present utility model is: a kind of high efficiency motor ship propeller, comprise propeller main body and for driving the electric machine assembly of propeller main body, one end of described electric machine assembly is provided with screw, described propeller main body comprises skull and is arranged on the joystick of skull one end, described electric machine assembly is connected with skull by a hollow pipe, the middle position of described hollow pipe is provided with a hanger bracket, described hollow pipe is fixed with a regulating sleeve by a hold-down bolt, described hollow pipe is also fixed with a depth adjustment ring by an adjusting bolt, motor is provided with in described electric machine assembly, described motor comprises the stator coil being arranged on motor centre position, magnetic pole is provided with outside described stator coil, rotor is provided with outside described magnetic pole.
Further, described regulating sleeve is positioned at the top of hanger bracket, and described depth adjustment ring is positioned at the top of regulating sleeve.
Further, described magnetic pole is rare-earth permanent magnet.
Further, described hanger bracket is fixed by bearing pin and hollow pipe.
Further, the side of described hanger bracket is provided with a clamper by a fishbolt.
Further, described hanger bracket is provided with multiple groove away from that side of fishbolt.
Apply a kind of high efficiency motor ship propeller provided by the utility model, its beneficial effect is: motor comprises the stator coil being arranged on motor centre position, magnetic pole is provided with outside stator coil, be provided with rotor outside magnetic pole, the advantage of the motor of this structure is that the generation position of torsion is more outer, and output torque is larger, and the design of external rotor can have larger spatial tessellations magnetic pole, magnetic field is stronger, thus improves the operating efficiency of whole thruster for electric ship, and operating efficiency is high.
