Embodiment Construction

[0023] The specific embodiments of the present invention will be described below in conjunction with the drawings.

[0024] Such as figure 1 , figure 2 As shown, the shaftless drive integrated motor propeller of the present invention is arranged at the tail of the hull 10 of the water surface or underwater vehicle, and is arranged in series by three sections of a front stator 3, a rotor propeller 4, and a rear stator 5 in a solid core. The non-rotating shaft 8 is composed of the inner periphery of the front stator 3 and the rear stator 5 is fixed on a solid non-rotating shaft 8, the outer periphery is fixed with a fastener 21 such as screws to accelerate or decelerate the duct 1, and the inner periphery of the rotor propeller 4 is pivotable It is arranged on a solid non-rotating shaft 8, and the outer circumference is rotatably fitted in the duct 1 through the propeller circumferential rim 43.

[0025] Such as figure 2 As shown, the front stator paddle 31 of the front stator 3 is...

Abstract

The invention discloses a shaftless driven type integrated motor propeller which is arranged on the tail part of a boat body of a water vehicle or underwater vehicle and comprises a front stator, a rotor propeller and a rear stator which are serially arranged on a solid non-rotating shaft, wherein the periphery of the propeller is connected with the circumferential rim of the annular propeller, a rotor permanent magnet is embedded in the circumferential rim of the propeller, a stator winding is arranged in the inner cavity of a guide pipe, the rotor permanent magnet and the stator winding are sealed by adopting water, and a gap is arranged between the rotor permanent magnet and the stator winding to form an annular motor. The rotor permanent magnet and the stator winding as well as the guide pipe are organically combined to form a modular unit, thus the shaftless driven type integrated motor propeller can be easily installed on a water platform or underwater platform, is suitable for large-power main propelling of a water boat or underwater submergible device, and has the advantages of reasonable structure, high propelling efficiency, low hydrodynamic force radiation noise, excellent cavitation property, safety and reliability.

Description

Technical field [0001] The invention relates to the field of ship propulsion, in particular to a shaftless drive type integrated motor propulsion. Background technique [0002] With the rapid development of ship technology, people’s requirements for ship propulsion devices have also been greatly improved. Traditional shaft-driven propellers have disadvantages such as noise, vibration and layout, and can no longer meet the requirements of surface and underwater high-performance platforms. There are two types of propellers that integrate motors and propellers. At present, there are mainly two forms: solid with core and hollow without core. [0003] The US patent document "Integral Motor Propulsor Unit For Water Vehicles" (US005220231A) is an integrated motor propeller with a hollow shaft. The propeller is a ducted propeller. The stator winding of the motor is installed inside the duct, and the circumferential rim of the rotor propeller The permanent magnets of the rotor are installe...
