The socket is rotatably mounted to the fixed shaft by the first and second bearings. The annular magnet is placed on the socket corresponding to the stator position. Wherein, the socket has a blade fixing portion, and the blade is attached to the blade fixing portion. In order to make the above content of the creation more obvious and easy to understand, the following is a detailed description of the embodiment and the accompanying drawings, and the following detailed description is given as follows: [Embodiment] The present invention proposes a ceiling fan and an outer rotor motor thereof, which are designed. Upper, the motor shaft is fixed, and the two bearing systems are disposed at the same-side end of the opposite stator position M365605. According to the structure proposed in this creation, the process used in this creation is simpler and faster than the conventional ceiling fan in the production crane (4) assembly process. Moreover, when the ceiling fan is in operation, the rotating components do not have to be covered with the upper cover, which is advantageous for improving the operation efficiency. Those with ordinary knowledge know that in the assembly process of producing ceiling fans, the fixed methods that can be applied between parts are countless. In addition to the most common screws and nuts, it is often used in shafts, bearings, etc. The design of the retaining ring, the fixing pin, the rib and the groove, etc. Therefore, in the following embodiments, the so-called fixing method may be various applicable conventional techniques, and the scope to be protected by the present invention is not limited thereto. . In addition, in the drawings, unnecessary components and design drawings are omitted, and the creative features are highlighted. Please refer to FIG. 2 to FIG. 3, and FIG. 2 illustrates an explosion diagram of the ceiling fan according to an embodiment of the present invention, and the third _ A cross-sectional view of the outer rotor motor after the ceiling fan assembly of Fig. 2 is shown. The ceiling fan 200 includes a support base 21, an outer rotor motor 22A, and a vane 230. The outer rotor motor 22A includes a fixed shaft center 221, a stator 222, and a rotor 223. The fixed shaft 221 is fixed to the support base 21, and the fixed latch 222 includes a set of cores 222c and excitation coils 222w, and is fixed to the fixed shaft 221 .

另外，外轉子馬達220更包括上蓋224，其固設於 固定軸心2U，用以遮罩住定子222及轉子223，以防 止積塵，提高產品壽命。 此外，外轉子馬達220更包括磁場感應元件225a。 磁場感應元件225a設置於電路板225b，連接一控制電 用以偵測轉子223之相對位置和轉速。磁場感應元 件225例如為一霍爾元件。 於疋，在生產吊扇的鈑立製程中，可以簡化傳統吊 扇結合上蓋與承座之步驟。而且，在定子奶、轴承⑽ 二223b、固定轴心221等部位，可以選用習知技藝中簡 單的固5又方式’例如凸肋與凹槽之設計限制旋轉自由 度’並搭配C型環限制上下位移等方法。 在第2圖及第3圖中’承座223d具有-貫穿孔 獅。在貫穿孔伽的”，具有—内凸緣223p% 轴承223a係位於内凸緣223p的上側，第二車由承雇 係位於内凸緣223p的下側。 由於在吊扇組立的製種中，組立偏斜是難以完全 M365605 避免的。因此’内凸緣223p上側之貫穿孔223h的直徑 較佳且非限定地係大於第一軸承223a的外徑，内凸緣 223p下侧之貫穿孔223h的直徑較佳且非限定地係大於 第二軸承223b的外徑。如此一來，當吊扇於運轉時， 環狀磁石223m帶動承座223d轉動，在組立偏斜之影 響下’此間隙可提供緩衝的空間。同時，在磁場的作用 下，此間隙可以予轉子浮動的空間，降低轉動產生的磨 擦。 在本實施例中，承座223d係使用一體成形的方式 製成，但其成本較咼。因此，為了進一步地降低成本 本創作更提出另一實施例，予熟悉此技藝者作為參考。 請參照第4圖，其緣示本創作另一實施例之外轉 子馬達的剖面圖。第4圖係相似於第3圖，兩者之差別 在於外轉子馬達420之承座423d係由一軸承襯套42^ 及一沖壓製造的盤體423r組合而成’藉此可大幅地降 低零部件的成本。第4圖其他元件係與第3圖相似，故 不再贅述。 综上所述，雖然本創作已以較佳實施例揭露如上， 然其並非用以限定本創作。本創作所屬技術領域中具有 通常知識者，在不脫離本創作之精神和範圍内，當可作 各種之更動與潤飾。因此，本創作之保護範圍當視後附 之申請專利範圍所界定者為準。 M365605 【圖式簡單說明】 第1圖繪示一種應用外轉子馬達之吊扇的爆炸圖。 第2圖繪示本創作一實施例之吊扇的爆炸圖。 第3圖繪示第2圖之吊扇組立後的外轉子馬達的 剖面圖。 第4圖緣不本創作另一實施例之外轉子馬達的剖 面圖。 【主要元件符號說明】 〔習知〕In addition, the outer rotor motor 220 further includes an upper cover 224 fixed to the fixed shaft center 2U for covering the stator 222 and the rotor 223 to prevent dust accumulation and improve product life. Further, the outer rotor motor 220 further includes a magnetic field sensing element 225a. The magnetic field sensing element 225a is disposed on the circuit board 225b and is coupled to a control circuit for detecting the relative position and rotational speed of the rotor 223. The magnetic field sensing element 225 is, for example, a Hall element. Yu Yu, in the process of producing a ceiling fan, can simplify the steps of combining the traditional ceiling fan with the upper cover and the seat. Moreover, in the stator milk, the bearing (10) two 223b, the fixed axis 221, etc., it is possible to select a simple solid 5 in the conventional technique, such as the design of the rib and the groove to limit the rotational freedom, and with the C-ring limit. Up and down displacement and other methods. In Figures 2 and 3, the shoe 223d has a through-hole lion. In the through-hole gamma, the inner flange 223p% is located on the upper side of the inner flange 223p, and the second vehicle is located on the lower side of the inner flange 223p. The set skew is difficult to completely avoid by M365605. Therefore, the diameter of the through hole 223h on the upper side of the inner flange 223p is preferably and not limited to be larger than the outer diameter of the first bearing 223a, and the through hole 223h of the lower side of the inner flange 223p The diameter is preferably and non-limitingly larger than the outer diameter of the second bearing 223b. Thus, when the ceiling fan is in operation, the annular magnet 223m drives the bearing seat 223d to rotate, and the gap can provide cushioning under the influence of the group deflection. At the same time, under the action of the magnetic field, the gap can pre-rotate the space of the rotor, reducing the friction caused by the rotation. In the present embodiment, the socket 223d is made by an integral forming method, but the cost is relatively low. Therefore, in order to further reduce the cost, another embodiment is proposed, which is referred to by those skilled in the art. Referring to Figure 4, there is shown a cross-sectional view of a rotor motor in accordance with another embodiment of the present invention. Similar to Fig. 3, the difference between the two is that the bearing 423d of the outer rotor motor 420 is formed by a combination of a bearing bush 42^ and a stamped disc 423r, thereby greatly reducing the cost of components. The other components in Fig. 4 are similar to those in Fig. 3, and therefore will not be described again. In summary, although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present invention. Those who have the usual knowledge can make various changes and refinements without departing from the spirit and scope of this creation. Therefore, the scope of protection of this creation is subject to the definition of the patent application scope attached.
