Description

Improved structure of disc generator

The present invention relates to a generator, in particular to an improved structure of a disc type generator which uses the configuration of triple dislocation between the coil winding body and the magnet block of the inner and outer rings to make the rotor rotate more smoothly.

Press, the function of the generator is to convert kinetic energy into electrical energy, the kinetic energy is input into the generator through the power shaft, and the permanent magnet on the rotor interacts with the coils of the corresponding stator group to generate electrical energy and output through the wire to the application side. The second press, driven by the kinetic energy, the rotor drives the magnets on the rotor to rotate synchronously, and then the magnetic field lines of the magnets produce magnetic cutting on the coils on the stator, so that the magnetic field of the coils on the stator changes, and then an induced current is generated to generate electricity, which is a disc type generator. The principle of electric power generation.

Press again, the coil of the disc generator must meet the following characteristics: (1) The thickness of the coil must be consistent, the distance between the coil and the magnet can be effectively reduced, the magnetic cutting coil can be averaged, the magnetic force can be improved, and the generator can not be The phenomenon of jitter will occur; (2) The number of turns of the coil must be the same, the internal resistance can be effectively reduced, and the power output can be smooth; (3) The winding direction of the coil must be the same, and the direction of the induced current will be the same, if the current If the directions are not the same, the two reverse currents will cancel each other out, and the power generation benefit will not increase but decrease.

As shown in FIG. 1, the structure of the disk generator with the patent number TW M599054 includes a stator carrier disk 910, a rotating shaft portion 920, two rotor carrier disks 930, a plurality of magnetic elements 931 arranged on the rotor carrier disk 930, and a plurality of rings. A coil winding body 940 disposed on the stator carrier plate 910, at least one coil portion 960 continuously wound on the coil winding body 940, and the number of turns and the winding direction of each coil winding body 940 are the same, and magnetic The elements 931 and the coil winding bodies 940 are regularly arranged in quantity to effectively increase the current value of each coil part 960 and superimpose the power generation of each coil winding body 940 .

After investigation, the cross-sectional area of the coil winding body 940 near the axis is much smaller than that near the outer periphery. As shown in FIG. 2, because the coil near the axis is over-extruded, and because the wire diameter of the winding has a certain size , so the magnetic flux density near the shaft center will be much larger than that at the outer periphery. Due to the difference in magnetic flux density, the operation of the rotor carrier plate 930 and the shaft portion 920 will be unsmooth, which will further reduce the output of the induced current and reduce the benefits of electricity generation.

Considering that the cross-sectional area of the coil winding body of the conventional disc generator is greatly different, which affects the power generation efficiency, how to reduce the variation of the magnetic flux density in the coil winding body has become a problem that the inventors actively think about and want to break through.
