Description of the Invention: [Technical Field] The present invention relates to a tubular linear reciprocating generator of direct drive, and more particularly to a three-phase toroidal coil provided with a slotless (Slotless) and a Halbach roar The permanent magnetic ring can be applied to tubular linear generators on various linear prime movers. [Prior Art] Conventionally, conventional generators use a common rotating type of rotor in the direction of movement of the mover. The prime mover of the rotary type generator is used for the silo =, the turbine of the firepower Wei or the wheel of the bicycle. In the original _ _ _ = temple ^ Na 卩 之 ( (4) (four) electricity ' However, now / there are other linear reciprocating type of prime mover, such as Stirling (four) ^ 擎's system motion. However, when driving the history, the direction of the object of the machine is linear to the belt of β belt, gear or chain, and the changing mechanism first changes to a rotary motion, and then passes through the shoulder. Therefore, the construction and transmission can be lowered. Interesting in the mechanical miscellaneous _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ U.S. Patent Publication No. 4,5, discloses "Linear reciprocating electrical generatator", which includes a mover and a stator. The mover system is provided with two rows of magnets, and the magnetic poles N and s of the rows of magnets are staggered, and the direction of the magnet is perpendicular to the linear reciprocating direction (i.e., the axial direction) of the mover. The stator has two thinner shapes, and the subdivision is formed into a plurality of petals for a plurality of coils. When the trim is linearly reciprocated, the magnet of the contact and the coil of the stator can induce current. In addition, the United States 4th, the lake, the milk number of the patent can not be miscellaneous can also be set to the second and several, and the mover can be changed to have two rows of magnets. However, the design of the contact and the stator does not provide the minimum induced magnetic field path, which is not conducive to achieving higher power output efficiency. Furthermore, U.S. Patent Publication No. Saga discloses a "Linear dec-Mcal machine for elect_ 〇r n^ive d: ive" which includes a mover and a stator. The scorpion has a first, a second magnet ring, a second magnet ring and a soft iron shaft. The first magnet core, the second magnet ring and the third magnet ring are sequentially arranged on the soft iron shaft. The N-face of the second magnet ring is straight to the (four) of the hybrid iron shaft and is directed radially outward. The N-poles of the first and third magnet rings are parallel to the axial direction of the soft-rod and are directed inwardly toward the second magnet ring. The stator is provided with a core and a coil, and the core is covered with the coil. When the mover performs linear reciprocating operation, the magnet ring of the mover can generate current. However, since the soft iron shaft of the mover has a miscellaneous ', the induced magnetic field path will have a partial loss of energy through the = shaft. Furthermore, the soft _ rod can also be accidentally introduced into the magnetic field to generate thermal energy, resulting in an increase in operating temperature, which in turn affects the magnetic strength of the magnet ring 1355131. In addition, the structure in which the core entirely covers the coil is not easy to manufacture, and it is also disadvantageous in that the number of adjacent coils is increased. Other related prior art techniques include a "linear generator apparatus" of U.S. Patent No. 7,250,697, which includes a first tube body and a first tube body, the first tube body being provided with a The coil is used as a stator. The second pipe body is provided with a group of stalks. The insertion of the second tube is difficult to garnish: call the first - official body. The magnet group is composed of a plurality of magnets, and the magnets also have magnetic poles arranged in series with the same polarity facing each other (ie, N poles to 1 poles, or s poles to s poles). Therefore, the minimum inductance is still not provided. The magnetic field path is not conducive to obtaining higher power output efficiency. σ has more than this, it is necessary to provide - lining hair, making it suitable for linear motion of the county machine, without any conversion of Lin, financial efficiency to reduce transmission efficiency losses, and at the same time solve the existing technology of linear generators Defects to further reduce this amount of loss and improve power generation output efficiency.

Referred to Figures 1, 2 and 3, the plurality of toroidal coils of the preferred embodiment of the present invention are radially wound by a predetermined number of turns by at least one metal wire (e.g., copper enameled wire). The wire diameter and the radial thickness of the coils 21 are the same as the output voltage. The winding number, the coil wire diameter and the radial thickness are different depending on the actual power generation requirements. The toroidal coil 21 includes at least (2n+l) loops=coils' and each of the lions and _21 series is annular, and is tightly stacked toward each other to become a single-small (Sbtiess) U-Mr. _Architecture, bit = the outer side of the axis 11. The above three-phase winding system is the same as that of a general AC electric generator, and therefore, the detailed description will not be repeated here. The value of the hiding is that the axial width w3_distance is substantially equal to the permanent magnetic ring of each permanent magnetic ring ==% or the axial width wl, w2 (or spacing) of the axial magnetic ring, or each of the _ / The axial width W of the magnetic ring or the axial magnetic ring W2 can be the width of each of the twists W3 (her), for example, 2 times. In this way, take the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Preferably, the preferred embodiment of the present invention is made of a guide stone 卞 卞 (4), for example, a thin 40 made of Nippon Steel, and an axial sleeve 22 is provided in the _ On the outside, and in the direction of the magnetic field lines of the magnetic field, the magnetic lines can flow to the magnetic field of the shortest 13 1355131. Furthermore, as shown in FIG. 5, in order to reduce the disadvantage of the excessively high-conductivity magnetic material:::=damage, the present invention; = ^1, the outer and outer stacking components have a predetermined thickness outside the magnetic flux sleeve 哕f Between the 221 and the 221 can be a close to her tight adhesion. = The steel sheet 221 can be a cylindrical stone sheet, or a sheet-like sheet, and then formed into a sheet. The smaller the thickness of the sheet 221, the more the eddy current is, and the magnetic There will be less stagnation and female damage. In addition, as shown in FIG. 6, the present invention may also be arranged such that a plurality of Shishi steel bars 222 are axially annularly arranged to have a predetermined thickness outside the magnetic sleeve 22', wherein each of the steel bars 222 is substantially Long strips and can be used to find the secret _. ^ Smoothly along the material guide county b to ensure that the magnetic field line travels in the axial direction of the turn 4 22, the outer magnetic sleeve 22 can be manufactured by various appropriate additions, and thus the ship is in the upper mode. . The inner fixing sleeve of the preferred embodiment of the present invention is preferably made of a low magnetic conductive material, such as a stainless steel of the Japanese melon standard of 3 〇 4 . By selecting a low magnetic permeability material, the present invention ensures that the inner fixing sleeve 23 does not affect the magnetic field of view. The fixing sleeve 23 is sleeved on the inner side of the ring _ 21 for fixing the toroidal coil 2 and ensuring that there is a fine air gap 3 between the mover i and the stator 2. Further, by narrowing the thickness of the closing sleeve 23, the magnetic flux density of the air gap 3 can be relatively increased. In addition, the distance between the air gaps 3 needs to be properly controlled to avoid excessive magnetic flux density caused by excessive spacing, or too small a pitch to cause wear, heat generation and noise of the mover i and the stator 2. 14 1355131 Referring to Figures 2 and 3, a linear bearing 24 of the preferred embodiment of the present invention is respectively disposed on two sides of the stator 2 of the tubular linear reciprocating generator for supporting the mover shaft 11 The two ends of the mover (4) are slidably passed through the two-wire bearing 24, respectively. The linear bearing 24 is for reducing frictional heat generation between the stator shaft 2 and the stator 2 during linear reciprocation, and relatively closes the internal space of the tubular linear reciprocating generator. The two linear bearings 24 are respectively fixed on the two side covers 25 of the stator 2 of the tubular line φ reciprocating generator, and the two side covers 25 are combined with each other by a plurality of coupling elements 26 (such as a screw and a nut). In order to combine all of the above elements of the tubular reciprocating generator. Referring to FIG. 2 again, in the preferred embodiment of the present invention, the tubular line of the direct drive, the reciprocating power generation, and the dimension design of each component are as follows: the position of the moving shaft 1 is 15 The radial thickness of the insulating sheath 12 is preferably about 6 _ 'the radial thickness of the permanent magnetic ring i3 is preferably about 1G, and the air gap between the mover and the fixed air is 3 ο. The radial thickness of the annular ring 2 is greater than 1 gram = 8 coffee, the radial thickness of the outer magnetic sleeve 22 is preferably about 5 _, and the radial thickness of the outer sleeve 23 is preferably about 3 The present invention is pure-tone, and the size is not limited to the present invention. The present invention can also appropriately change the size design of each component. The line is the original, the direct motive of the embodiment, and the original motive (not driven, so that the mover) two 15 == striking side details _ good 2, Lai ^ no grooved pottery (four) three pure shape The light is transmitted, and the reciprocating movement of the tearing axis is performed to perform linear power generation. The permanent magnetic ring 13, the toroidal coil 21 and the outer magnetically permeable sleeve 22 are linearly reciprocated while the movable shaft 11 is linearly reciprocating in the axial direction. A plurality of annular induced magnetic fields are generated along the drawing direction. Since the permanent magnetic ring 13, the toroidal coil 21, and the magnetic sleeve 22 are arranged in a circular inner and outer direction, each of the annular induced magnetic field paths is also 360 degrees. At this time, the magnetic pole direction of the first to 2=31 to 137 of the permanent magnetic ring 13 is in the direction of the magnetic field line of the guided magnetic field path. As shown in Fig. 4, the female 々 々 日 4 4 4 ft W η纟Right to left divided into several counter-clockwise directions and a plurality of ring-shaped magnetic fields arranged adjacent to the direction of the needle, and each of the two ring-shaped induced magnetic fields share the same-radial outward or radial inward permanent magnetic ring & When the magnetic field line passes through the toroidal coil 21, the toroidal coil generates an induced current to achieve the purpose of power generation. An experimental result of the embodiment of the Ming 7 shows that when the speed of a linear prime mover is two! 2, it can be estimated that the tubular linear reciprocating generator of the direct drive can output the left and right of the horsepower, and the miscellaneous_moving speed is mixed. The energy output of the surface can be obtained. If the wire inspection machine can only provide a limited speed, then the magnetic enthalpy: the magnetic field is reduced, and the pitch is reduced, thereby obtaining a higher U degree in the air gap 3, thereby Shouting the voltage to increase the output of the power supply. Twenty-two: Compared with the conventional rotary type generator or linear generator, the === path' is not conducive to obtaining higher power generation output efficiency. The permanent magnetic sum of the child 1 is Halbach 16 (3) 5131 ring system _ and the second class of the _ Gu 21's non-frequency class clothing secret Chinese style winding, which provides a variety of silky prime mover ^ linear generator ' Linshi can guide the magnetic field lines to move in the direction of the shortest magnetic field path. _ It can increase the density of the induced magnetic field, increase the magnetic field strength and improve the power output efficiency. _ The overall structure is simple, easy to maintain and turn. Moreover, due to the ring-shaped induced magnetic field The magnetic field line actually After the mover axis u, the material of the rudder shaft 11 only needs to use a low magnetic material, so it is also beneficial to reduce the loss of the overall energy and the amount of heat generated by the heat loss of the mover. The permanent magnetic ring 13 of the mover i is fixed on the mover shaft u by the insulating sheath 12, and the insulating 'sleeve 12 prevents the heat input by the linear prime mover from affecting the magnetic strength of the permanent magnetic ring 13, thus The magnetic strength of the permanent magnetic ring can be ensured. Although the invention has been disclosed in the preferred embodiments, it is not intended to limit the invention to those skilled in the art, without departing from the spirit and scope of the invention. Various changes and modifications are intended to be included, and the scope of the invention is defined by the scope of the appended claims.
