Description of the Invention: [Technical Field] The present invention relates to an integrated permanent magnet synchronous power generation system, and more particularly to a same drive shaft capable of efficiently generating power at different speeds. An integrated permanent magnet synchronous power generation system that can effectively reduce its overall size. [Prior Art] In the case where the petrochemical energy is nearing depletion, renewable energy sources such as wind power or solar energy have been widely used to generate electricity. Among them, because the power generation efficiency of solar power generation is still very limited, the current commercial solar power generation applications require a large amount of space for solar panels, such as the size of dozens of football fields, in order to generate enough power for consumers to use. In comparison, wind power generation does not require much space, and because wind power = the fan blades of the motor unit are vertically disposed, the wind turbine can be applied to two limited environments, such as urban areas. At present, the Wu group included in the wind power generation includes: an axial flux type permanent magnet synchronous power generation module and a radial flux type hydromagnetic synchronous power generation module, each of which has the advantages and disadvantages of not (four), as shown in the following, The axial flux type permanent magnet synchronous power generation module has the advantage of having a very small torque due to its stator side in the wind=iron"1, which is suitable for using rd%4. However, due to the axial flux type The magnet system setting of the magnetic synchronous power generation board group / % package is always large (the magnet needs to reach _==:, so the thickness of the magnet _ 疋), in order to generate a magnetic field of sufficient intensity of 201208232 in the central part to generate electricity. The bulky magnet not only has a weight of one turn, but also has a considerable material cost, which limits the application field of the axial flux permanent magnet synchronous power generation module. In addition, since the winding guide system is placed in the center thereof Partly, the thermal energy generated by the magnetic field cutting is not easy to dissipate, and it is easy to generate overheating. Secondly, the radial flux type permanent magnet synchronous power generation module has its stator windings placed in the slots of its stator core, so Process For the sake of simplicity, the radial flux type permanent magnet synchronous power generation module uses much less magnet than the axial magnetic flux-type permanent magnet synchronous power generation module, so its weight and cost are much smaller than the axial flux type. The magnetic synchronous power generation module. However, the radial magnetic flux type permanent magnet synchronous power generation module has a high "torque torque", which is easy to cause the radial magnetic flux type permanent magnet synchronous power generation module to be difficult to start (ie, its startup) Higher wind speed). Wherein, the aforementioned "torque torque" is a rotor of a permanent magnet synchronous motor having a tendency to align with the stator in a certain direction, and an oscillating torque is generated, which is called cogging torque or Turn torque. Therefore, the axial flux type permanent magnet synchronous % power generation module and the radial magnetic flux type permanent magnet synchronous power generation module currently applied to wind power generation have their application limitations and cannot be widely applied in various environments. (If it can be applied to small winds in urban areas and large winds in the sea), it still cannot achieve a better balance between cost and power generation efficiency. Therefore, there is a need in the industry for an integrated permanent magnet synchronous power generation system that can efficiently generate power at different drive bearing speeds and that can effectively reduce its overall size. 201208232 SUMMARY OF THE INVENTION The main object of the present invention is to provide an integrated permanent magnet synchronous power generation system, which refers to a same drive shaft and different speeds, and is efficiently generated by different permanent magnet synchronous power generation modules. electric power. Another object of the present invention is to provide an integrated permanent magnet synchronous power generation system capable of effectively reducing the overall size of a permanent magnet synchronous power generation system while generating the same amount of electric power. To achieve the above object, the integrated permanent magnet synchronous power generation system of the present invention comprises an axial flux type permanent magnet synchronous power generation module comprising an axial rotor unit, an axial stator unit and a front axial fixed portion. a radial magnetic flux type permanent magnet synchronous power generation module comprising a radial direction stator unit, a front radial fixed casing and a rearward slanting port * and a solid The outer casing has a front surface, and the fixed outer casing is formed by the axial flux permanent magnet synchronous power generation module and the radial magnetic flux permanent magnet synchronous power generation module; and the drive bearing system Passing through the front surface of the fixed casing and connecting with the axial rotor unit and the radial rotor unit. The radial flux permanent magnet synchronous power generation module is the axial flux permanent magnet synchronous power generation module. The group is surrounded by it. Therefore, since the integrated permanent magnet synchronous power generation system of the present invention includes both an axial magnetic flux type permanent magnet synchronous power generation module and a radial magnetic flux type permanent magnet synchronous power generation group, the integrated permanent magnet synchronization of the present invention The power generation system can efficiently generate electricity with different permanent magnet synchronous power generation modules in the same-drive shaft and different speeds. For example, in a wind power environment with less wind power, use - including an axial 201208232 magnetic flux j permanent magnet synchronous power generation module with a large power generation and a radial magnetic flux permanent magnet with a small power generation. The matching mode of the synchronous power generation module is to effectively utilize the advantage that the axial flux type permanent magnet synchronous power generation module has a small torque. On the other hand, in a wind power environment with large wind power, an axial flux permanent magnet synchronous power generation module including a small power generation power and a radial magnetic flux type with a large power generation are used. The matching method of the magnetic synchronous power generation module is advantageous in that the radial magnetic flux type permanent magnet synchronous power generation module is low in cost and easy to dissipate heat. In addition, since the radial magnetic flux type permanent magnet synchronous power generation module of the integrated permanent magnet synchronous power generation system of the present invention surrounds the axial magnetic flux type permanent magnet synchronous power generation module, The integrated permanent magnet synchronous power generation system of the present invention can effectively utilize the space in the center of the radial flux type permanent magnet synchronous power generation module, that is, the axial magnetic flux type permanent magnet synchronous power generation module is accommodated therein to make the integration of the present invention The permanent magnet synchronous power generation system can effectively reduce the overall size under the premise of generating the same amount of power.

In the present embodiment, the axial rotor unit 11 has a front axial rotor magnet 111 and a rear axial rotor magnet 112. The axial stator unit 12 has a first axial stator coil winding 121 and a second. An axial stator coil winding 22 and a third axial stator coil winding 1 23 . Further, in the present embodiment, the first axial stator coil winding 1 21, the second axial stator coil winding 1 22, and the third axial stator coil winding 123 have different phases, respectively. As shown in FIG. 4, in the axial magnetic flux type permanent magnet synchronous power generation module of the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention, the front axial rotor magnet 111 and the rear axial rotor magnet The first axial stator coil winding 12 1 , the second axial stator coil winding 1 22 and the third axial stator coil winding 123 are sandwiched between the two. On the other hand, the front axial fixed casing 3 and the rear axial fixed casing 14 sandwich the front axial rotor magnet 1 and the rear axial rotor magnet 112 therebetween. Further, the front axial rotor magnet 111 is fixed to the front axial fixed casing 13, and the rear axial rotor magnet 1 I 2 is fixed to the rear axial fixed casing 4. 201208232 Moreover, the thickness of the front axial rotor magnet Η丨 is the same as the thickness of the rear axial rotor magnet Π 2 to provide a symmetrical magnetic field distribution. In this embodiment, the material of the front axial rotor magnet m and the rear axial rotor magnet 丨丨2 may be neodymium iron boron or iron oxide magnet; preferably, the neodymium iron boron magnet material can provide a larger The magnetic field strength increases the back electromotive force peak and increases the power. In addition, since the front axial rotor magnet 丨n and the rear axial rotor magnet 112 have the same cross-sectional area, and the magnetic field strength that the magnet can provide is related to the magnet The volume is proportional to the relationship, and the power of the generator (the ability to generate electricity) is proportional to the strength of the magnetic field cut by the coil.

At this time, the axial rotor single-turner of the axial flux type permanent magnet synchronous power generation module starts to move relative to the axial stator unit 丨2 of the axial flux type permanent magnet synchronous power generation module 1, so that The first axial stator coil winding 121, the second axial stator coil winding 22, and the third axial stator coil winding 123 begin to cut a magnetic field jointly generated by the axial rotor magnet 1丨丨 and the rear axial rotor magnet U2. Further, power generation (power generation) is started. At the same time, the radial rotor unit 21 of the radial flux type permanent magnet synchronous power generation module 2 also starts to move relative to the radial stator unit 22 of the radial flux type permanent magnet synchronous power generation module 2, The radial stator coil windings of the radial stator unit 22 begin to cut a magnetic field generated by the radial rotor magnets 212, thereby initiating the generation of electrical power (power generation). Therefore, in the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention, the 'axial magnetic flux type permanent magnet synchronous power generation module 201208232 1 and the radial magnetic flux type permanent magnet synchronous power generation module 2 can simultaneously generate electric power ( Power generation).
況且,如圖1及圖3所示,在本發明一實施例之整合 式永磁同步發電系統中,徑向磁通型永磁同步發電模組2 係將轴向磁通型永磁同步發電模組1圍繞於其中,且軸向 磁通型永磁同步發電模組1之轴向轉子單元n之後軸向轉 子磁石1 1 2的外徑(R 1)係略小於徑向磁通型永磁同步發電 模組2之徑向轉子單元2 1之徑向轉子矽鋼片21 1的内徑 (R2)。所以,位於徑向磁通型永磁同步發電模組2中央的 空間便可用於容納軸向磁通型永磁同步發電模組丨於其 中,使得原本在習知徑向磁通型永磁同步發電模組2中被 閒置的中央空間可被有效地被利用。 因此,本發明一實施例之整合式永磁同步發電系統 便可於產生相同數值之電力的前提下,有效地縮小永磁同 步發電系統的總體尺寸。相對地,在以往的發電系統中, 如果要將軸向磁通型永磁同發電模組與徑向磁通型永磁同 步發電模組整合在—起時,—般的處理方式係將轴向磁通 型水磁同步發電模組與徑向磁通型永磁同步發電模組分別 利用兩座平台架構相鄰地排列’再利用控制電路將兩者作 連接,不只結構複雜且所耗成本也較高。 …需注意的是,在某些制環境下,前述之轴向轉子 =11之❹向轉子磁石112的外徑(Rl)亦可與徑向轉子 早兀21之徑向轉子矽鋼片211的内徑相同。如此, 3將轴向轉子單70丨1(如後轴向轉子磁石丨12)與經向轉子 201208232 單元21 (如徑向轉子矽鋼片2 11)結合在一起,使得兩者以 相同的速率轉動,亦可簡化本發明一實施例之整合式永磁 同步發電系統之轉子結構。 而如前所述’雖然習知之軸向磁通型永磁同步發電 模組具有體積龐大,材料(磁石)成本高,且散熱不易等缺 點,但由於其具有頓轉轉矩非常小的優點,所以習知之軸 向磁通型永磁同步發電模組的啟動風速較低,較適合用於 位於市區的風力發電系統。另一方面,雖然習知之徑向磁 通型永磁同步發電模組具有頓轉轉矩較大的缺點,但由於 其具有製程fel單、材料(磁石)成本低,易於散熱的優點, 所以習知之徑向磁通型永磁同步發電模組的啟動風速較 高,較適合用於位於海邊的風力發電系統。 因此,由於本發明一實施例之整合式永磁同步發電 系統係同時包括一軸向磁通型永磁同步發電模組及一徑向 磁通型永磁同步發電模組,且徑向磁通型永磁同步發電模 組係將軸向磁通型永磁同步發電模組圍繞於其中。所以本 發明一實施例之整合式永磁同步發電系統不僅可有效地利 用其内部空間’更可於不同的驅動軸承轉速情況下,以不 同的永磁同步發電模組搭配方式有效率地產生電力。例 如’在風力較小的風力發電環境中(如都會及市區),本發 明一實施例之整合式永磁同步發電系統便可採用一發電功 率為7 kW(6〜8 kW)之軸向磁通型永磁同步發電模組及一 發電功率為3 kW(4〜2 kW)之徑向磁通型永磁同步發電模 組的搭配方式’以避免用已經較小的風力去推動頓轉轉矩 201208232 較大之徑向磁通型永磁同步發電模組,造成發電效率無法 J.Q 曰 提幵0 另一方面,在另一風力較大的風力發電環境中(如海 邊)’本發明一實施例之整合式永磁同步發電系統便可採 用一發電功率為3 kW(4〜2 kW)之軸向磁通型永磁同步 發電模組及一發電功率為7 kW(6〜8 kW)之徑向磁通型 永磁同步發電模組的搭配方式,以用較大的風力推動頓轉 轉矩較大之徑向磁通型永磁同步發電模組,有效提昇發電 的總量’且避免讓不易散熱的軸向磁通型永磁同步發電模 組積存過多的熱量,造成發電機過熱。 上述實施例僅係為了方便說明而舉例而已,本發明 所主張之權利範圍自應以申請專利範圍所述為準,而非僅 限於上述實施例。 【圖式簡單說明】 圖1係本發明一實施例之整合式永磁同步發電系統的爆炸 示意圖。 圖2係顯示本發明一實施例之整合式永磁同步發電系統之 外觀的示意圖。 圖3係沿著圖2中之A A’連線所得之剖面示意圖。 圖4係本發明一實施例之整合式永磁同步發電系統所具之 轴向磁通型永磁同步發電模組的爆炸示意圖。 圖5係本發明一實施例之整合式永磁同步發電系統所具之 把向磁通型永磁同步發電模組的爆炸示意圖。 201208232 【主要元件符號說明】 1 軸向磁通型永磁同步發電模組 2 徑向磁通型永磁同步發電 3 固定外殼 11 軸向轉子單元 1 3前軸向固定殼 21 徑向轉子單元 23前徑向固定殼 31前表面 112 後軸向轉子磁石 122第二軸向定子線圈繞組 2 H fe向轉子石夕鋼片 221徑向定子線圈繞組 R1後軸向轉子磁石的外徑 模組 4 驅動車由承 1 2 軸向定子單元 1 4後軸向固定殼 22 徑向定子單元 24後徑向固定殼 111 前軸向轉子磁石 121 第一軸向定子線圈繞組 123 第三軸向定子線圈繞組 212徑向轉子磁石 222 空向定子珍鋼片 R2把向轉子石夕鋼片的内徑Moreover, as shown in FIG. 1 and FIG. 3, in the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention, the radial magnetic flux type permanent magnet synchronous power generation module 2 is an axial magnetic flux type permanent magnet synchronous power generation system. The module 1 is surrounded therein, and the outer diameter (R 1) of the axial rotor magnet 1 1 2 after the axial rotor unit n of the axial flux permanent magnet synchronous power generation module 1 is slightly smaller than the radial flux type The inner diameter (R2) of the radial rotor steel piece 21 1 of the radial rotor unit 21 of the magnetic synchronous power generation module 2. Therefore, the space in the center of the radial flux type permanent magnet synchronous power generation module 2 can be used to accommodate the axial flux type permanent magnet synchronous power generation module, so that the conventional radial flux type permanent magnet is synchronized. The central space that is idle in the power generation module 2 can be effectively utilized. Therefore, the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention can effectively reduce the overall size of the permanent magnet synchronous power generation system while generating the same amount of electric power. In contrast, in the conventional power generation system, if the axial flux permanent magnet is integrated with the power generation module and the radial flux permanent magnet synchronous power generation module, the general processing method is to rotate the shaft. The flux-type hydromagnetic synchronous power generation module and the radial magnetic flux type permanent magnet synchronous power generation module are respectively arranged by using two platform architectures to re-use the control circuit to connect the two, which is not only complicated in structure but also costly. Also higher. It should be noted that, in some manufacturing environments, the outer diameter (R1) of the axial rotor = 11 to the rotor magnet 112 may also be within the radial rotor steel sheet 211 of the radial rotor 21 The path is the same. Thus, 3 combines the axial rotor single 70丨1 (such as the rear axial rotor magnet 丨12) with the warp rotor 201208232 unit 21 (such as the radial rotor 矽 steel sheet 2 11) so that both rotate at the same rate. The rotor structure of the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention can also be simplified. As mentioned above, although the conventional axial flux type permanent magnet synchronous power generation module has the advantages of bulky size, high material (magnet) cost, and low heat dissipation, it has the advantage of having a very small torque. Therefore, the axial flux type permanent magnet synchronous power generation module of the prior art has a low starting wind speed, and is suitable for a wind power generation system located in an urban area. On the other hand, although the conventional radial flux type permanent magnet synchronous power generation module has the disadvantage of large torque, but it has the advantages of a process fel, a low material (magnet) cost, and easy heat dissipation. The radial flux type permanent magnet synchronous power generation module has a high starting wind speed and is suitable for a wind power system located at the seaside. Therefore, the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention includes an axial flux permanent magnet synchronous power generation module and a radial magnetic flux permanent magnet synchronous power generation module, and the radial magnetic flux The permanent magnet synchronous power generation module surrounds the axial flux permanent magnet synchronous power generation module. Therefore, the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention can effectively utilize the internal space to efficiently generate electric power with different permanent magnet synchronous power generation modules in different driving speeds of different driving bearings. . For example, in a wind power environment with less wind power (such as metropolis and urban area), the integrated permanent magnet synchronous power generation system according to an embodiment of the present invention can adopt an axial power generation capacity of 7 kW (6 to 8 kW). Magnetic flux type permanent magnet synchronous power generation module and a matching mode of radial flux type permanent magnet synchronous power generation module with a power of 3 kW (4~2 kW) to avoid using the already small wind force to push the turn Torque 201208232 Large radial flux-type permanent magnet synchronous power generation module, resulting in power generation efficiency can not be JQ 幵 幵 0 On the other hand, in another wind power environment with large wind power (such as the seaside) 'The invention one The integrated permanent magnet synchronous power generation system of the embodiment can adopt an axial magnetic flux type permanent magnet synchronous power generation module with a power generation of 3 kW (4 to 2 kW) and a power generation of 7 kW (6 to 8 kW). The matching method of the radial magnetic flux type permanent magnet synchronous power generation module is to promote the total amount of power generation by using a radial wind flux type permanent magnet synchronous power generation module with a large wind force and a large torque. Avoid excessive accumulation of axial flux permanent magnet synchronous power generation modules that are not easy to dissipate heat Amount, causing the generator to overheat. The above-described embodiments are merely examples for the convenience of the description, and the scope of the claims is intended to be based on the scope of the claims, and not limited to the above embodiments.
