Description
Technical field
The present invention relates to Propeller technology field, and in particular to a kind of new culvert type propeller device and its realization side
Method.
Background technology
The resistance being primarily present during propeller motion has air frictional resistance, pressure drag, induced drag and interference drag
Deng.Blade makes speed highest at blade tip because of high speed circular motion, and than larger, air-flow produces impact to cause to make an uproar to induced drag to external world
Sound is big, and this is the low main cause of free spiral rotation oar dynamic efficiency.Traditional free spiral rotation oar generally uses cantilever beam structure,
Being easily deformed at blade tip under pneumatic action causes efficiency further to deteriorate, and this is one of bottleneck of limitation propeller high-speed motion,
It is also the key of propeller aeroplane and helicopter rate limitation.
The content of the invention
In order to solve the above problems, it is to provide a kind of new culvert type propeller device and in fact that the purpose of the present invention is
Existing method, is favorably improved propeller efficiency, reduces propeller noise；Reduce motor diameter, improve the applicability of motor..
To achieve the above objectives, the present invention is adopted the following technical scheme that：
A kind of new culvert type propeller device, including hollow cylindrical motor stator 1, on the outer wall of motor stator 1
Multiple coils 5 are uniformly wrapped, inwall and the outer shroud of bearing 3 of motor stator 1 are connected；Rotor 2 is mutually nested by two
Tubular structure and loop configuration composition, and two mutually nested tubular structures by loop configuration at the end of tubular structure
Portion is linked together, and the tubular structure inside rotor 2 is passed through from the center of bearing 3, and is connected with the inner ring of bearing 3, electricity
Tubular structure outside machine rotor 2 is enclosed within the outside of motor stator 1, and magnetic sheet 4 is inlaid with inwall；Motor stator 1, motor turns
Son 2 and bearing 3 are symmetrical structure and symmetrical overlapping of axles, and motor stator 1 is connected by wire with drive and control of electric machine module 8；
The blade tip at the two ends of propeller 7 is connected with the tubular structure inwall inside rotor 2, due to the hollow knot inside rotor 2
Structure, forms the duct of air flow.
The method that described new culvert type propeller device realizes rotation, drive and control of electric machine module 8 is given by wire
The galvanization of coil 5 on motor stator 1, coil 5 produces magnetic field and motor rotor 2 rotates, and rotor 2 drives propeller
7 rotations.
Compared with prior art, the invention has the advantages that：
The present invention is different from the advantage of traditional propeller device, is rotor and stator design into hollow cylindrical, and
Propeller is fixed in the rotor of motor, due to the hollow structure of internal rotor, the duct of air flow, and spiral shell is formd
The blade tip for revolving oar is fixed on rotor, and blade tip will not deform when rotating at a high speed, be favorably improved propeller efficiency, reduce spiral
Oar noise, in addition rotor be designed to cylindric, in the case where equal torque is exported, be conducive to reducing motor diameter, carry
The applicability of motor high.
