Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
Fig. 2-4 are schematic diagrams of a dc non-ruggedized specific power generator 100 according to a preferred embodiment of the invention. Fig. 2 is a working principle diagram, fig. 3 is a structural schematic diagram of a stator (end face), and fig. 4 is an internal schematic diagram (side face) of a direct-current non-ruggedness special-effect generator.
As shown in fig. 2, the direct current no-ruggedness-effect generator 100 includes an inner rotor 10, an outer rotor 30, and a stator 20. The inner rotor 10 is a cylindrical magnet having an N-pole outer side surface, and the outer rotor 30 is a cylindrical magnet having an S-pole inner side surface. The inner diameter of the outer rotor 30 is larger than the outer diameter of the inner rotor 10, so that a wider space is provided between the inner wall of the outer rotor 30 and the outer wall of the inner rotor 10. The inner rotor 10 and the outer rotor 30 rotate in opposite directions with the same axial lead as the axis, and the stator 20 is fixed in the space between the inner rotor 10 and the outer rotor 30 by a stator support seat. As shown in fig. 3, the stator 20 includes a circular ring cylindrical support body 21 and an over-wound winding 22 (fig. 4). The inner wall surface and the outer wall surface of the circular cylindrical support body 21 are provided with a plurality of grooves 211 with the same number, the envelope winding 22 comprises continuous envelopes 220 wound along the inner wall surface and the outer wall surface of the circular cylindrical support body 21, and the continuous envelopes 220 are embedded into the grooves 211 of the inner wall surface and the outer wall surface of the circular cylindrical support body to be fixed during winding. Each single group of envelope (a group of envelope refers to a groove wound on the inner wall surface of the stator and a circle of winding wire wound on an adjacent groove on the outer wall surface) is connected in series, the directions of magnetic fields generated by currents in each single group of envelope are consistent and form an integral closed magnetic field (the direction indicated by B in figure 2), the closed magnetic field hardly has the leakage problem, therefore, the reluctance force action on the rotor is avoided, and the power generation efficiency of the generator is improved. The groove 211 is T-shaped, i.e. the inner end is wider for accommodating a plurality of turns of the covered wire, and the outer end is wider (the end connected to the outer wall surface of the circular cylindrical support body 21) for only inserting a single covered wire 220, so as to prevent the continuous covered wire 220 from falling out of the groove 211. As shown in fig. 3, the annular cylindrical support 21 has 40T-shaped grooves on the outer wall surface and 40T-shaped grooves on the inner wall surface. In other embodiments, the number of grooves is not limited.
When the outer rotor 30 is driven to rotate counterclockwise and the inner rotor 10 is driven to rotate clockwise, the covered wire winding 22 will cut the magnetic lines of force, so that the directional direct current is generated in the covered wire winding 22. The concave groove 211 is a groove structure extending along the length direction of the annular cylindrical support body 21 on the outer wall surface and the inner wall surface of the annular cylindrical support body 21, and is approximately parallel to the axis of the annular cylindrical support body 21. Wherein, the circular cylindrical support body 21 is an integral structure of magnetic conductive metal material (ferromagnetic) so as to form a magnetic field loop; or a structure formed by overlapping and combining a plurality of annular silicon steel sheets.
In the solution of the present invention, the inner rotor 10 and the outer rotor 30 may be ordinary magnets, and one end of the outer side surface of the inner rotor 10 and one end of the inner side surface of the outer rotor 30 are made into opposite magnetic poles. For example, the outer side surface of the inner rotor 10 is an N pole (only the N pole of the outer side surface is labeled in fig. 2), the inner side surface of the outer rotor 30 is an S pole (only the S pole of the inner side surface is labeled in fig. 2), the inner side surface of the inner rotor 10 is an S pole (not labeled), and the outer side surface of the outer rotor 30 is an N pole (not labeled). Alternatively, one magnetic pole of the magnet may be displayed on the surface (e.g., the S magnetic pole on the inner side of outer rotor 30 is displayed) and the other magnetic pole may be hidden from view (e.g., the N magnetic pole on the outer side of outer rotor 30 is hidden) by a hiding technique.
As shown in fig. 4, the dc sleeveless special-effect generator 100 of the present invention further includes a housing 101 and a base 102. Wherein one end of the stator 20 is fixed at the end of the casing 101, the stator 20 is wound with the covered wire winding 22, and the stator 20 is not rotatable; and the outer rotor 30 and the inner rotor 10 extend out of the driving rods from the other end of the housing 101, respectively. In addition, in order to drive the inner rotor 10 and the outer rotor 30 to rotate reversely, a driving device is provided, a rotational energy output end of which is provided with a first bevel gear 41, a driving rod of the outer rotor 30 is provided with a second bevel gear 31, and a driving rod of the inner rotor 10 is provided with a third bevel gear 11. The second bevel gear 31 and the third bevel gear 11 are engaged with opposite sides of the first bevel gear 41, so that the driving end of the same driving device can drive the inner rotor 10 and the outer rotor 30 to rotate in opposite directions. Wherein, the driving device is a wind turbine, a steam turbine, a water turbine or any equipment or device which can drive the outer rotor and the inner rotor to rotate reversely.
