習知散熱風扇通常係藉由一馬達驅動其扇輪旋轉作動，以達到預定之散熱作用。一般而言，習知馬達大致包含一基座(或基板)、一定子及一轉子；該基座用以支撐該定子及該轉子，該定子結合該基座，該轉子可旋轉地結合該定子，以便利用該定子驅動該轉子旋轉作動。又，為使該轉子可穩定旋轉，目前市面上常見之習知馬達另可在該基座或基板上設置如平衡磁鐵、平衡環、平衡片或其他具有相同功能之構件，用以維持該轉子平衡旋轉；以下係揭示數種具有可使轉子平衡旋轉之習知馬達結構，其中：請參照第1圖所示，如中華民國第I256440號之「風扇馬達轉子之轉動平衡構造」發明專利案；係揭示第一種習知馬達5，該習知馬達5係於一基座51上設有一軸管52、一轉子53、一平衡磁鐵54及一感磁部55。該軸管52設於一定子56之中央；該轉子53設有一軸座531及一軸桿532，該軸桿532一端結合該軸座531，另一端可旋轉地結合該軸管52；該平衡磁鐵54設在該軸管52之頂端；該感磁部55結合於該軸座531。藉此，該平衡磁鐵54可對應磁吸該感磁部55，以維持該轉子53之轉動及啟動之平衡。Conventional cooling fans are usually driven by a motor to drive their fan wheels to achieve a predetermined heat dissipation. In general, a conventional motor generally includes a base (or substrate), a stator and a rotor for supporting the stator and the rotor, the stator is coupled to the base, and the rotor rotatably couples the stator In order to use the stator to drive the rotor to rotate. Moreover, in order to make the rotor stably rotate, conventional motors commonly available on the market may be provided with a balancing magnet, a balance ring, a balance piece or other components having the same function on the base or the substrate for maintaining the rotor. Balanced rotation; the following discloses several conventional motor structures that can make the rotor balance and rotate. Among them, please refer to the invention patent case of "Rotational Balance Structure of Fan Motor Rotor" of the Republic of China No. I256440; The first conventional motor 5 is disclosed. The conventional motor 5 is provided with a shaft tube 52, a rotor 53, a balance magnet 54, and a magnetic sensing portion 55 on a base 51. The shaft tube 52 is disposed at the center of the stator 56. The rotor 53 is provided with a shaft seat 531 and a shaft 532. The shaft 532 is coupled to the shaft seat 531 at one end and rotatably coupled to the shaft tube 52 at the other end. 54 is disposed at a top end of the shaft tube 52; the magnetic sensitive portion 55 is coupled to the shaft seat 531. Thereby, the balance magnet 54 can magnetically absorb the magnetic sensitive portion 55 to maintain the balance of rotation and activation of the rotor 53.
然而，上述第一種習知馬達5必須另行將該平衡磁鐵54安裝於該軸管52之頂端，以及將該感磁部55安裝於該轉子53之軸座531；因此，造成組裝作業上極大的不便，並導致該馬達5之構件數量繁多且製造成本提高；再者，該轉子53之軸座531與該軸管52之間必須保留可供該感磁部55及該平衡磁鐵54容置的空間，故亦無法有效降低該馬達5之整體軸向高度。However, the first conventional motor 5 described above must separately mount the balance magnet 54 to the top end of the shaft tube 52, and the magnetic sensitive portion 55 is attached to the shaft seat 531 of the rotor 53; therefore, the assembly work is extremely large. Inconvenience, and the number of components of the motor 5 is increased and the manufacturing cost is increased. Further, the shaft seat 531 of the rotor 53 and the shaft tube 52 must be retained for the magnetic sensitive portion 55 and the balance magnet 54 to be accommodated. Therefore, the overall axial height of the motor 5 cannot be effectively reduced.
請參照第2圖所示，如中華民國第590330號之「具平衡馬達轉子之構造」新型專利案；係揭示第二種習知馬達6，該習知馬達6大致包含一定子61、一平衡磁鐵62、一轉子63及一金屬殼64。該平衡磁鐵62設置於該定子61上；該轉子63具有與該定子61相對的一永久磁鐵631；該金屬殼64結合於該轉子63內側。藉此，該平衡磁鐵62與該金屬殼64之間可產生平衡磁力，以維持該轉子63平衡旋轉。Please refer to FIG. 2, for example, the new patent of "Construction with Balanced Motor Rotor" of the Republic of China No. 590330; revealing a second conventional motor 6, which generally comprises a stator 61, a balance A magnet 62, a rotor 63 and a metal shell 64. The balance magnet 62 is disposed on the stator 61; the rotor 63 has a permanent magnet 631 opposite to the stator 61; the metal shell 64 is coupled to the inside of the rotor 63. Thereby, a balance magnetic force can be generated between the balance magnet 62 and the metal shell 64 to maintain the rotor 63 in balanced rotation.
然而，上述第二種習知馬達6必須於該轉子63內側結合該金屬殼64，造成該轉子63之製作成型時的諸多不便，且亦必須另行將該平衡磁鐵62安裝於該定子61上，因此，該馬達6之組裝便利性仍不佳，其同樣具有構件數量繁多且製造成本較高等缺點；再者，該轉子63與該定子61之間必須保留可供該金屬殼64及該平衡磁鐵62容置的空間，故仍無法有效降低該馬達6之整體軸向高度。However, the second conventional motor 6 described above must be coupled to the metal shell 64 inside the rotor 63, which causes inconvenience in the molding of the rotor 63, and the balance magnet 62 must be separately attached to the stator 61. Therefore, the assembly convenience of the motor 6 is still poor, and it also has the disadvantages of a large number of components and a high manufacturing cost. Further, the metal shell 64 and the balance magnet must remain between the rotor 63 and the stator 61. The space occupied by 62 is still unable to effectively reduce the overall axial height of the motor 6.
請參照第3圖所示，如中華民國第I257757號之「馬達之轉子平衡構造」發明專利案；係揭示第三種習知馬達7，該習知馬達7至少包含一基座71、一第一平衡磁鐵72、一轉子73、一第二平衡磁鐵74。該基座71用以支撐一定子711；該第一平衡磁鐵72結合於該基座71上；該轉子73可旋轉地結合該定子711；該第二平衡磁鐵74結合該轉子73且與該第一平衡磁鐵72相對。藉此，該第一及第二平衡磁鐵72、74可在軸向上對應磁吸，以有效維持該轉子73之旋動平衡。Please refer to FIG. 3, for example, the invention patent of the "motor rotor balance structure" of the Republic of China No. I257757; the third conventional motor 7 is disclosed, the conventional motor 7 includes at least a base 71, a first A balance magnet 72, a rotor 73, and a second balance magnet 74. The base 71 is for supporting a stator 711; the first balance magnet 72 is coupled to the base 71; the rotor 73 is rotatably coupled to the stator 711; the second balance magnet 74 is coupled to the rotor 73 and A balance magnet 72 is opposite. Thereby, the first and second balance magnets 72, 74 can be magnetically attracted in the axial direction to effectively maintain the swirl balance of the rotor 73.
然而，上述第三種習知馬達7必須於該基座71及該轉子73分別安裝該第一及第二平衡磁鐵72、74，因此，同樣具有組裝不便、結構複雜及製造成本較高等諸多缺點；另外，該轉子73於長時間旋轉作動的過程中，亦可能產生如該第二平衡磁鐵74容易脫落等問題；再者，由於該軸座71安裝有該第一平衡磁鐵72，故仍無法有效降低該馬達7之整體軸向高度。However, the third conventional motor 7 described above has to mount the first and second balance magnets 72, 74 on the base 71 and the rotor 73, respectively, and thus has the disadvantages of inconvenient assembly, complicated structure, and high manufacturing cost. In addition, during the long-time rotation of the rotor 73, problems such as the second balance magnet 74 being easily detached may occur. Further, since the first balance magnet 72 is mounted on the shaft base 71, it is still impossible. The overall axial height of the motor 7 is effectively reduced.
請參照第4圖所示，如中華民國第501823號之「馬達之平衡環構造」發明專利案；係揭示第四種習知馬達8，該馬達8係以一基板81供一定子座82結合，該定子座82可供一轉子83可旋轉地結合，該轉子83具有一永久磁鐵831，該基板81另結合一平衡環84，該平衡環84具有一環牆841。藉此，該平衡環84之環牆841可與該永久磁鐵831之底段對應相磁吸，以維持該轉子83之旋轉平衡。Please refer to FIG. 4, for example, the invention patent of the "motor balance ring structure" of the Republic of China No. 501823; the fourth conventional motor 8 is disclosed, which is coupled with a certain base 82 by a substrate 81. The stator base 82 is rotatably coupled to a rotor 83 having a permanent magnet 831 which is further coupled to a balance ring 84 having a ring wall 841. Thereby, the ring wall 841 of the balance ring 84 can be magnetically attracted to the bottom section of the permanent magnet 831 to maintain the rotation balance of the rotor 83.
然而，上述第四種習知馬達8之平衡環84必須另形成豎立狀之環牆841，故該平衡環84之結構較為複雜，且製造成型較為不易，而該環牆841之設計亦會導致該馬達8之整體軸向高度增加；再者，於實際使用時，仍必須另行將該平衡環84安裝於該基板81上，因此，同樣會造成組裝作業上極大的不便。However, the balance ring 84 of the above-mentioned fourth conventional motor 8 must be formed into a vertical annular wall 841. Therefore, the structure of the balance ring 84 is relatively complicated, and manufacturing is relatively difficult, and the design of the ring wall 841 can also result in The overall axial height of the motor 8 is increased. Further, in actual use, the balance ring 84 must be separately attached to the substrate 81, which also causes great inconvenience in assembly work.
綜上所述，上述各種具有可使轉子平衡旋轉之習知馬達5、6、7、8普遍皆具有結構複雜、組裝不便、不易縮減軸向高度及製造成本較高等缺點；另外，以上僅揭示數種較具代表性之馬達結構，其他如中華民國公開第200638658號「馬達構造」發明專利案、中華民國第I246817號「馬達轉子之轉動平衡構造」發明專利案、中華民國第M243848號「馬達之旋轉平衡構造」新型專利案等，大致皆是在基座或基板上另結合有平衡片等構件，因此，同樣具有前揭各項缺點；另外，如中華民國第421369號之「無刷直流馬達平衡定位及其磁極片構造」新型專利案，則是直接於一定子的其中一磁極片形成具有平衡功能之環體磁極片，造成該定子在製造組裝上之諸多不便，故皆有加以改善之必要。In summary, the above-mentioned various conventional motors 5, 6, 7, and 8 which can balance the rotation of the rotor generally have the disadvantages of complicated structure, inconvenient assembly, difficulty in reducing axial height, and high manufacturing cost; Several representative motor structures, such as the invention patent case of "Motor Construction" issued by the Republic of China Public No. 200638658, the invention patent case of "Rotary Balance Structure of Motor Rotor" of the Republic of China No. I246817, and the motor of the Republic of China No. M243848 The new patent case of the rotary balance structure, etc., is basically a combination of a balance piece and the like on the base or the substrate, and therefore has the disadvantages disclosed above; and, for example, the "brushless DC" of the Republic of China No. 421369 In the new patent case of motor balance positioning and pole piece construction, a magnetic pole piece with balanced function is formed directly on one of the pole pieces of the stator, which causes many inconveniences in the manufacture and assembly of the stator, so it is improved. Necessary.
本發明目的乃改良上述各種具有可使轉子平衡旋轉之習知馬達的缺點，其係藉由一平衡件取代習知馬達之基座，以便在保有使轉子可平衡旋轉之功能的條件下，可更進一步降低整體結構複雜度。SUMMARY OF THE INVENTION The object of the present invention is to improve the above-mentioned various conventional motors having a balance of rotation of the rotor, which replaces the base of the conventional motor by a balance member so as to maintain the function of balancing the rotation of the rotor.

The balance member 11 is for supporting the stator 12 and the rotor 13; the stator 12 is coupled to the balance member 11; the rotor 13 is rotatably coupled to the stator 12; thereby, the stator 12 can be used to drive the rotor 13 to rotate. The balance piece 11 is used to make the rotor 13 stably rotate.
該平衡件11具有一表面111，該表面111設有一軸接部112及一感磁部113；其中該軸接部112可一體成型於該表面111，或可利用組裝方式結合於該表面111，且該軸接部112可為軸管、軸座或其他可供該轉子13可旋轉地結合之構件或結構設計；於本實施例中，該軸接部112係為一軸管，該軸管可供容置如耐磨片114、扣持片115或軸承116等構件；另外，該感磁部113較佳為形成於該平衡件11之表面111的凸環。The balance member 11 has a surface 111. The surface 111 is provided with a shaft portion 112 and a magnetic sensing portion 113. The shaft portion 112 can be integrally formed on the surface 111 or can be assembled to the surface 111 by assembly. The shaft joint portion 112 can be a shaft tube, a shaft seat or other member or structural design that can be rotatably coupled to the rotor 13; in the embodiment, the shaft joint portion 112 is a shaft tube, and the shaft tube can be The magnetic sensitive portion 113 is preferably a convex ring formed on the surface 111 of the balance member 11 for receiving a member such as the wear-resistant piece 114, the fastening piece 115 or the bearing 116.
該定子12係結合該平衡件11，於如圖所示之實施例中，該定子12係結合於該軸接部112之外周面。The stator 12 is coupled to the balance member 11. In the embodiment shown in the figure, the stator 12 is coupled to the outer peripheral surface of the shaft portion 112.
該轉子13包含一輪轂131、一轉動軸132及一永久磁鐵133，該轉動軸132及該永久磁鐵133設置於該輪轂內側131，該轉動軸132可旋轉地結合該平衡件11之軸接部112，該永久磁鐵133與該定子12之間具有一氣隙；又，該永久磁鐵133另具有一磁吸面134，該磁吸面134朝向該平衡件11之表面111，且該磁吸面134與該平衡件11之感磁部113相互對位。The rotor 13 includes a hub 131, a rotating shaft 132 and a permanent magnet 133.

更詳言之，本發明之平衡件11係選用可與該永久磁鐵133相互磁吸之構件，例如：該平衡件11可為磁鐵板片、金屬板片、......等；藉此，本發明馬達1不論在運轉、靜止或啟動時，由於該平衡件11之感磁部113皆可與該磁吸面134在軸向上相互磁吸，因此，可適當維持該轉子13之旋轉平衡及轉動穩定性。More specifically, the balance member 11 of the present invention is a member that can be magnetically attracted to the permanent magnet 133.

Balance and rotational stability.
藉由前揭之結構特徵，本發明第一實施例之馬達1的主要特點至少包含有：可利用該平衡件11直接取代習知馬達的基座或基板，該平衡件11可用以支撐該定子12及該轉子13等構件，並利用取代基座或基板的該平衡件11予以維持該轉子13的旋轉平衡；因此，相較於習知馬達普遍必須在基座或基板上另行設置如平衡磁鐵、平衡環、平衡片等構件(或於定子形成具有相同功能的結構等)，本發明馬達1無疑可降低結構複雜度、提升組裝便利性及減少製造成本，並兼可有效縮減該馬達1之整體軸向高度，以便朝向更輕薄短小化的方向研發設計。另外，亦由於本實施例之感磁部113係為形成於該平衡件11之表面111的凸環，因此，使得該感磁部113更為貼近該磁吸面134，以更進一步提升該平衡件11之平衡效果，進而有效防止該轉子13於旋轉過程中產生不當晃動及噪音等情形；再者，利用該凸環之結構設計，亦可增加該平衡件11之結構強度，使該平衡件11可更適合作為支撐該定子12及該轉子13之用途。The main features of the motor 1 of the first embodiment of the present invention include at least a base or a substrate that can directly replace a conventional motor, and the balance member 11 can be used to support the stator. 12 and the rotor 13 and the like, and the balance of the rotor 13 is maintained by the balance member 11 instead of the base or the substrate; therefore, it is generally necessary to separately provide a balance magnet on the base or the substrate as compared with the conventional motor. , such as a balance ring, a balance piece, etc. (or forming a structure having the same function in the stator, etc.), the motor 1 of the present invention can undoubtedly reduce structural complexity, improve assembly convenience, and reduce manufacturing cost, and can effectively reduce the motor 1 The overall axial height is designed to be developed in a direction that is lighter, thinner and shorter. In addition, since the magnetic sensitive portion 113 of the present embodiment is a convex ring formed on the surface 111 of the balance member 11, the magnetic sensitive portion 113 is brought closer to the magnetic surface 134 to further enhance the balance.
