Technical Field

The invention belongs to the technical field of aerospace, and particularly relates to a carbon-magnetic mixed spherical rotor and a manufacturing method of the rotor.

Background

The generator is a mechanical device for converting energy of other forms into electric energy, and is driven by a gasoline engine, a diesel engine or other power machines, converts the energy generated by fuel combustion into mechanical energy and transmits the mechanical energy to the generator, and then the mechanical energy is converted into the electric energy by the generatorBearing assemblyAnd the like. The stator is composed of a stator core, a coil winding, a base and other structural members for fixing the parts. The rotor is composed of rotor iron core (or magnetic pole, yoke) winding, protective ring, central ring, slip ring, fan and rotary shaft. The stator and the rotor of the generator are connected and assembled by the bearing and the end cover, so that the rotor can rotate in the stator and does the motion of cutting magnetic lines of force, thereby generating induced potential, the induced potential is led out through the wiring terminal and is connected in a loop, and then current is generated. Conventional generators made of metal are too heavy to load the aircraft, affecting flight.

In recent years, with the development of the unmanned aerial vehicle market, the electric multi-rotor unmanned aerial vehicle rapidly gains attention of the broad consumer groups with the advantages of excellent control performance, convenience in vertical take-off and landing and the like, and becomes the most popular product so far. Compared with other unmanned aerial vehicles, the multi-rotor unmanned aerial vehicle has the advantage of being extremely thick, and compared with a fixed-wing aircraft, the multi-rotor unmanned aerial vehicle has the advantages of being capable of taking off and landing vertically and being capable of hovering at a fixed point; compared with a single-rotor helicopter, the helicopter has no tail rotor device, so that the helicopter has the advantages of simple mechanical structure, high safety, low use cost and the like. But the load capacity is small, the endurance time is short, and the battery needs to be replaced frequently after each rack.

The fuel power multi-rotor unmanned aerial vehicle has the advantages of large load and long endurance. But has the disadvantages of environmental pollution, high operation difficulty, short service life of the engine and high cost.

Disclosure of Invention

In order to overcome the defects that the existing electric multi-rotor unmanned aerial vehicle is small in load capacity and short in endurance time, the fuel-powered multi-rotor unmanned aerial vehicle pollutes the environment, the operation difficulty is high, and the service life of an engine is short, the invention provides a carbon-magnetic mixed spherical rotor of a brand-new ultra-light aircraft generator and a manufacturing method of the rotor, wherein the carbon-magnetic mixed spherical rotor is 60% lighter than the traditional generator in weight and generates electricity by utilizing compressed air generated in flight.

The technical scheme adopted by the invention for solving the technical problems is as follows: a carbon-magnetic mixed spherical rotor and its making method features that its stator is an annular pipe to form a closed circuit, so it is directly installed in the stator pipe of electric generator. A carbon-magnetic mixed spherical rotor is made up of permanent-magnet powder, light charcoal powder and water adhesive through mixing, and coating teflon casing outside the mixture of permanent-magnet powder and light charcoal powder for reinforcing and self-lubricating. Adding permanent magnet powder and light charcoal powder into glue water = 1; 99, feeding the magnetic powder and the light charcoal powder into a vertical stirrer, uniformly stirring, feeding into a ball forming mill, forming balls, drying and smoothing the appearance of finished balls until no water stain can be seen by naked eyes, drying, feeding into a round hole sorting screen, sorting out qualified finished products, and coating a polytetrafluoroethylene shell by using a spraying mode. The finished product of the wrapped carbon-magnetic mixed spherical rotor is placed in water and floats on the water surface as a standard, and the diameter of the round hole sorting sieve is determined according to the diameter of the stator pipeline of the generator

The determined diameter of the carbon-magnetic mixed spherical rotor is also fixed, and whether the carbon-magnetic mixed spherical rotor can float on the water surface is achieved by adjusting the proportion of the magnetic powder and the light charcoal powder. A process flow; permanent magnet powder, light charcoal powder and water cement → are evenly stirred in a vertical stirrer → are balled in a ball forming mill → are dried → are sorted by a circular hole sorting sieve → are sprayed with a tetrafluoroethylene shell → are packaged in finished products → are put in storage.

The carbon-magnetic mixed spherical rotor and the manufacturing method thereof have the advantages that full-automatic waste-free production can be realized, the weight of the product is 60% lighter than that of the traditional generator, and the process and the product structure are simple.
