Embodiment Construction

[0018] Such as Figure 1~Figure 3 As shown, the marine permanent magnet motor propeller of the present invention includes a motor, a casing 8 and a propeller. The motor is a permanent magnet motor, which contains a stator and a rotor, and the stator contains a stator cover 9 . Both the stator cover 9 and the casing 8 are cylinders, the stator cover 9 is located in the casing 8 and the two are fixedly fitted. Stator coils 10 are evenly distributed in the circumferential direction of the inner circle of the stator cover 9 , and an insulating layer 12 is wrapped on the outside of the stator coils 10 . The insulating layer 12 is made of plastic.

[0019] The rotor includes a rotor sleeve 18 which is a cylinder, and the rotor sleeve 18 is concentric with the casing 8 and the stator sleeve 9 . Permanent magnets 11 are evenly distributed in the circumferential direction of the inner circle of the rotor sleeve 18 , and there is a gap between the permanent magnets 11 and the stator ...

Abstract

The invention relates to a ship-used permanent magnet motor propeller, which comprises a motor, a shell and a propeller, and is characterized in that the motor is a permanent magnet motor; the permanent magnet motor comprises a stator and a rotor; the stator comprises a stator sleeve; the stator sleeve is located inside the shell; the stator sleeve is internally, circumferentially and uniformly provided with stator coils; an insulated layer is arranged outside the stator coil; the rotor comprises a rotor sleeve; permanent magnets are circumferentially and uniformly arranged inside the rotor sleeve; a gap is left between the permanent magnet and the stator coil; bearings are arranged between two ends of the stator sleeve and two ends of the rotor sleeve; two ends of the stator sleeve and two ends of the rotor sleeve are provided with round air guide sleeves; the air guide sleeve has a nearly conical cross section, and two edges are respectively connected with the same ends of the shell and the rotor sleeve; paddle blades are circumferentially and uniformly arranged inside the rotor sleeve; and the rotor sleeve and the inner circumferential paddle blades form the propeller. The ship-used permanent magnet motor propeller is simple in structure, small in size, small in occupied space, and little in noise, facilitates health of an operator, can avoid environmental pollution, and can be applied to a ship.

Description

technical field [0001] The invention relates to a marine propeller. Specifically, it is a permanent magnet motor propeller that adopts a permanent magnet motor as power and is suitable for use on ships. Background technique [0002] It is well known in the shipbuilding industry that the propellers currently used on ships are all traditional propellers. This traditional thruster comprises a casing, and motor, gear box, propeller are arranged in the casing, and propeller wherein is made up of paddle shaft and the paddle blade that is fixed on the paddle shaft. The output shaft of the motor is connected with the input shaft of the gearbox, and the output shaft of the gearbox is connected with the paddle shaft of the propeller. When working, the motor drives the propeller shaft and the turbine on the propeller shaft to rotate through the gearbox, thereby generating forward thrust to realize the propulsion of the ship. Since the traditional body propeller contains a motor, a g...
