Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of generator components, in particular to a high-efficiency magnetic conductive skeleton structure. Background Art
[0002] Claw-pole generators are widely used in small-scale power generation applications due to their low cost. Unlike traditional generators, claw-pole generators utilize claw-shaped magnetic poles for rotor excitation. Pairs of claws are mounted on the rotor shaft, each housing a magnetic yoke and excitation coil that generate a magnetic field. The stator core is constructed from stacked silicon steel sheets with excellent magnetic conductivity. Multiple slots are evenly distributed around the core's inner circumference, housing the stator coils and forming multiple windings. While claw-pole generators are inexpensive, they require multiple windings on the stator, making production more complex. Utility Model Content

[0035] See Figures 1 to 4 This embodiment provides an efficient magnetic conductive skeleton structure for installing a magnetizer 100 and a coil to form a stator. The stator is used to cooperate with the rotor 200 to form a generator. The efficient magnetic conductive skeleton structure includes a skeleton body 1, a fixing part 2, a winding part 3 and a hollow part 4.
[0036] There are multiple fixing parts 2, which are arranged around the skeleton body 1. The fixing parts 2 are used to fix the magnetic conductor 100. The fixing parts 2 include a first fixing part 21 close to one end of the skeleton body 1 and a second fixing part 22 close to the other end of the skeleton body 1. The first fixing part 21 and the second fixing part 22 are arranged alternately.
[0037] The winding portion 3 is disposed on the skeleton body 1 and is located relatively outside the fixing portion 2 . The winding portion 3 is used for winding the coil, and the winding direction of the winding portion 3 is the same as the layout direction of the fixing portion 2 .
[0038] The hollow portion 4 is provided on the skeleton body 1 and is located on an inner side opposite to the fixing portion 2 . The hollow portion 4 is used to place the rotor 200 so that the rotor 200 can rotate along the arrangement direction of the fixing portion 2 .
[0039] Among them, the magnetic conductor 100 is the claw stage, the first fixing portion 21 and the second fixing portion 22 are interlaced and surrounded to form a ring, the first fixing portion 21 is close to one end of the skeleton body 1, and the second fixing portion 22 is close to the other end of the skeleton body 1. Since the first fixing portion 21 and the second fixing portion 22 are used to fix the magnetic conductor 100, the arrangement of the multiple magnetic conductors 100 is consistent with the arrangement of the fixing portion 21, such as Figure 2As shown, multiple magnetizers 100 are divided into two groups, and the two groups of magnetizers 100 are respectively close to one end and the other end of the skeleton body 1. The two groups of magnetizers 100 are staggered with each other. The ring formed by the multiple magnetizers 100 is coaxial with the rotor 200. The rotor 200 is divided into multiple magnetic poles along its radial direction, that is, the circular cross-section of the rotor 200 is evenly divided into multiple sectors, each sector has a magnetic pole. When the rotor 200 rotates, the N-pole is facing one of the magnetizers 100, and the magnetic flux of the N-pole will pass through the magnetizer 100 directly above it, and then pass through the adjacent magnetizer 100. Returning to the adjacent S stage, the rotor 200 continues to rotate, and the magnetizer 100 facing the N stage changes from being close to one end of the skeleton body 1 to being close to the other end of the skeleton body 1. The N stage continues to pass through the opposite magnetizer 100 and the adjacent magnetizer 100 back to the adjacent S stage. However, since the magnetizer 100 facing the N stage changes from being close to one end of the skeleton body 1 to being close to the other end of the skeleton body 1, the direction of the magnetic flux from the N stage to the S stage changes, and the winding part 3 is surrounded by a wire coil, that is, the magnetic flux in the wire coil changes, thereby generating an induced current output.
[0040] In this embodiment, a first fixing portion 21 near one end of the skeleton main body 1 and a second fixing portion 22 near the other end of the skeleton main body 1 are staggeredly arranged around the skeleton main body 1, a hollow portion for placing the rotor 200 on the relatively inner sides of the first fixing portion 21 and the second fixing portion 22, and a winding portion 3 surrounding the relatively outer sides of the first fixing portion 21 and the second fixing portion 22 and used to surround the coil, so that the direction of the magnetic flux lines between the magnetizer 100 fixed on the first fixing portion 21 and the second fixing portion 22 can be continuously changed when the rotor 200 rotates, thereby changing the magnetic flux in the coil and generating an induced current output. Compared with the traditional claw-stage generator, the claw-stage structure is installed on the stator, thereby eliminating multiple windings on the stator, making production simpler and more efficient.
[0041] Further, see Figure 1 The skeleton body 1 is a sleeve structure, a winding portion 3 is formed on the outside of the sleeve structure, a hollow portion 4 is formed on the inside of the sleeve structure, and the fixing portion 2 is arranged around the inner wall of the sleeve structure.
[0042] Among them, the sleeve structure is a cylinder, the hollow part 4 is the hollow part of the cylinder, the winding part 3 is the outer wall of the cylinder, and the inner wall of the cylinder is provided with two groups of grooves. The two groups of grooves are respectively close to the two ends of the cylinder and are staggered. The two groups of grooves are respectively the first fixing part 21 and the second fixing part 22.
[0043] Furthermore, the inner side wall of the sleeve structure is provided with a plurality of grooves, which form a fixing portion 2. The fixing portion 2 is used to fix the magnetic conductor 100 inside the sleeve structure.
[0044] Furthermore, the adjacent side walls of any two adjacent grooves are beveled inwardly along the end direction thereof.
[0045] Specifically, the ends of the groove are indented inward on both sides, and the fixing part 2 is used to fix the magnet 100. The magnet 100 in this embodiment is the claw stage. Since the ends of the claw stage are indented inward, the fixing part 2, that is, the structure of the groove is adapted to the shape of the claw stage, and the side walls of the two ends of the adjacent grooves are beveled to form reinforcing ribs, thereby strengthening the structure of the skeleton body 1.
[0046] Furthermore, a wire groove is provided around the outer side of the sleeve structure, and the wire groove forms the winding portion 3 .
[0047] Specifically, retaining rings are provided at both ends of the sleeve structure, and a winding portion 3 is formed between the two retaining rings.
[0048] Furthermore, a wire hole 31 is provided through the side wall of the wire trough.
[0049] The wire hole 31 can allow the end of the coil wrapped around the winding part 3 to pass through, so as to avoid the coil being sealed when the shell is installed.
[0050] Furthermore, a limiting groove 32 is provided on the outer side of the wire trough side wall. One end of the limiting groove 32 is connected to the wire hole 31 , and the other end penetrates along the height direction of the wire trough side wall to form a bayonet 33 .
[0051] After the coil end passes through the wire hole 31 , it can continue to pass through the limiting slot 32 , thereby extending outward from the bayonet 33 , which can prevent the wire end from being clamped when the housing is installed.
[0052] Furthermore, the number of the fixing parts 2 is the same as the number of stages of the rotor 200 .
[0053] The fixing portion 2 is used to fix the magnetizer 100 . The number of stages of the rotor 200 affects the magnetic flux passing through the magnetizer 100 . To maximize the efficiency of the generator, the number of the fixing portions 2 is designed to be the same as the number of stages of the rotor 200 .
[0054] Furthermore, the number of the fixing parts 2 is 6.
[0055] The magnetic conductive skeleton provided in this embodiment is used in a micro-generator. The shaft diameter of the micro-generator rotor is not too large, so too many magnetic poles are not needed. In order to achieve higher power generation efficiency, the number of magnetic poles of the rotor 200 is usually 6, so the number of the fixing parts 2 is also designed to be 6.
[0056] Furthermore, one end of the groove passes through the end side of the sleeve structure and extends along the height direction of the side wall of the wire groove.
[0057] Specifically, an opening is provided on the side wall of the wire trough relative to the groove to facilitate installation of the base.
[0058] See Figure 4The first fixing portion 21 and the second fixing portion 22 are provided with the magnetizers 100 which can be divided into two groups. Each group of magnetizers 100 is connected to form an end shell. The two end shells can be respectively provided on both sides of the skeleton body 1. Figure 3 The end shell can be integrally formed from steel, with a magnetizer 100 formed inside and an annular structure formed outside to secure the skeleton body 1. During installation, the steel sheet connecting the magnetizer 100 inside the end shell and the annular structure outside abuts the extension of the groove to prevent displacement during operation. After being looped within the wire slot, the wire can pass through the wire hole 31 and then be arranged in the limiting groove 32.
[0059] Working principle:
[0060] like Figure 2 As shown, the fixing portion 2 is used to fix the magnetizer 100. The multiple magnetizers 100 are divided into two groups. The two groups of magnetizers 100 are respectively close to one end and the other end of the skeleton body 1. The two groups of magnetizers 100 are staggered with each other. The ring formed by the multiple magnetizers 100 is coaxial with the rotor 200. The rotor 200 is divided into multiple magnetic poles along its radial direction, that is, the circular cross-section of the rotor 200 is evenly divided into multiple sectors, each sector has a magnetic pole. When the rotor 200 rotates, the N-level is facing one of the magnetizers 100, and the magnetic flux of the N-level will pass through the magnetizer 100 directly above it, and then pass through the phase The adjacent magnetizer 100 returns to the adjacent S stage, and the rotor 200 continues to rotate. The magnetizer 100 facing the N stage changes from being close to one end of the skeleton body 1 to being close to the other end of the skeleton body 1. The N stage continues to pass through the opposite magnetizer 100 and the adjacent magnetizer 100 back to the adjacent S stage. However, since the magnetizer 100 facing the N stage changes from being close to one end of the skeleton body 1 to being close to the other end of the skeleton body 1, the direction of the magnetic flux from the N stage to the S stage changes, and the winding part 3 is surrounded by a wire coil, that is, the magnetic flux in the wire coil changes, thereby generating an induced current output.

The above is only a preferred implementation method of the present invention.
