Embodiment 1
[0048] see figure 1 , figure 2 , this embodiment provides a disc-type ironless generator 1000, specifically, including:
[0049] A plurality of stator disks 0200, one side of the stator disk 0200 has a plurality of coils (not shown) uniformly arranged along the circumferential direction of the stator disk 0200.
[0050] In this embodiment, the stator disk 0200 is preferably a disk-shaped structure, and the center of the stator disk 0200 has a through hole for passing through a rotating shaft (not shown in the figure). When the rotating shaft is passed through the through hole, if the rotating shaft Rotate, the stator disk 0200 will not rotate with the rotating shaft.
[0051] In this embodiment, the coils are preferably copper coils, and the number of coils is preferably six, which are evenly arranged on one side of the stator plate 0200 along the circumferential direction of the stator plate 0200 .
[0052] Preferably, as image 3 As shown, a first groove 0210 is arrange...
Embodiment 2
[0069] This embodiment provides another disc-type ironless generator (not shown in the figure). Compared with Embodiment 1, in this embodiment, the diversion bridge in the disc-type ironless generator is not an independent structure , but is directly formed by the rotor disc, which is suitable for places that do not require much power.
[0070] Specifically, its technical scheme is as follows:
[0071] include:
[0072] A plurality of stator disks, one side of the stator disk has a plurality of coils (not shown in the figure) uniformly arranged along the circumferential direction of the stator disk.
[0073] In this embodiment, the stator plate is preferably a disk-shaped structure, and the center of the stator plate has a through hole for passing through the rotating shaft (not shown in the figure). When the rotating shaft is passed through the through hole, if the rotating shaft rotates, The stator disc does not rotate with the shaft.
[0074] In this embodiment, the coil...

Abstract
The invention provides a disc-type coreless generator, and the generator consists of a stacked structure which is formed by the alternate arrangement of a plurality of stator discs and non-magnetic-conduction rotor discs. Two ends of the stacked structure are provided with the non-magnetic-conduction rotor discs with diversion bridges. The diversion bridges in the non-magnetic-conduction rotor discs and magnetic-conduction rotor discs can enable the magnetic circuits of the adjacent magnets on the same disc to be connected, thereby enabling the magnetic circuit to be used efficiently, and forming a closed loop in the disc-type coreless generator. The excellent directionality of the magnets is use efficiently, thereby forming a magnetic concentrating effect. Furthermore, the distance between the magnets is the diameter of the magnets, and the distance between the discs is less than the radius of the magnets, and the excellent directionality of the magnets is use efficiently, thereby avoiding the magnetic leakage and the field disturbing.
Description
technical field [0001] The invention relates to the field of generators, in particular to a disc-type ironless generator. Background technique [0002] Disk type ironless generators are usually used in vertical axiswind power generation systems. Existing disk-type ironless generators generally have only one stator disk, an upper turntable located above the stator, and a lower turntable located below the stator turntable. Multiple coils are arranged on the stator turntable along the circumferential direction, and the upper turntable and the lower turntable are provided with A plurality of permanent magnets, when the upper turntable and the lower turntable rotate relative to the stator disk, current is generated in the coil on the stator disk. Since there is only one stator disk, the existing disk-type iron-coreless generator has low power, low power generation, low power generation efficiency, and cannot meet the demand for high-power power generation.
