本發明係關於一種馬達及其定子線圈組與散熱風扇，尤其是一種以佈線方式形成線圈結構的定子線圈組，以及具有該定子線圈組的馬達及散熱風扇。The present invention relates to a motor and its stator coil assembly and a heat dissipating fan, and more particularly to a stator coil assembly in which a coil structure is formed by wiring, and a motor and a cooling fan having the stator coil assembly.
請參照第1圖所示，係揭示目前較常見之習知馬達定子8，該馬達定子8大致包含數個矽鋼片81、二絕緣套82及一線圈組83。該數個矽鋼片81係藉由堆疊方式相互結合；該二絕緣套82可分別結合於堆疊後之各該矽鋼片81的上、下二端；該線圈組83係由數個線圈分別纏繞於該絕緣套82之預定部位。Referring to FIG. 1 , a conventional motor stator 8 is disclosed. The motor stator 8 generally includes a plurality of silicon steel sheets 81 , two insulating sleeves 82 , and a coil assembly 83 . The plurality of silicon steel sheets 81 are combined with each other by stacking; the two insulating sleeves 82 can be respectively coupled to the upper and lower ends of each of the stacked silicon steel sheets 81; the coil group 83 is wound by a plurality of coils respectively. The predetermined portion of the insulating sleeve 82.
然而，目前市面上常見之習知馬達已逐漸朝向微型化方向研發設計，惟該習知馬達定子8主要係由相互堆疊之數個矽鋼片81所構成，因此，並不易降低整體軸向高度；再者，習知馬達定子8仍必須藉由該絕緣套82之設計，用以保護該線圈組83及使該矽鋼片81與該線圈組83之間具有絕緣效果，故該二絕緣套82亦會造成該馬達定子8之體積及軸向高度增加；因此，當該馬達定子8應用於如第2圖所示之習知馬達時，將使該習知馬達之整體體積及軸向高度無法有效縮減，導致該馬達無法達到微型化之目的。However, the conventional motors that are commonly available on the market have gradually been developed in the direction of miniaturization. However, the conventional motor stator 8 is mainly composed of a plurality of silicon steel sheets 81 stacked on each other, and therefore, it is not easy to reduce the overall axial height; Moreover, the conventional motor stator 8 must still have the design of the insulating sleeve 82 for protecting the coil assembly 83 and the insulating effect between the silicon steel sheet 81 and the coil assembly 83. Therefore, the two insulating sleeves 82 are also This will cause an increase in the volume and axial height of the motor stator 8; therefore, when the motor stator 8 is applied to a conventional motor as shown in Fig. 2, the overall volume and axial height of the conventional motor will not be effective. The reduction has caused the motor to fail to achieve miniaturization.
為此，如第3圖所示之中華民國專利號201103234號「馬達定子及其線圈組」發明專利申請案係揭示一種可以用以取代前述馬達定子8的習知定子線圈組9，該定子線圈組9包含一基板91及一線圈組92。該線圈組92係形成於該基板91之表面，且該線圈組92包含有數個佈線層921，該數個佈線層921表面分別形成數個線圈922及一導接部923，各該線圈922電性連接該導接部923，其中相鄰二佈線層921之導接部923係相互電性導通。藉此，該定子線圈組9應用於馬達結構時，可有效降低軸向高度及縮減體積。To this end, the invention patent application of the "Motor Stator and Its Coil Set", as shown in Fig. 3, discloses a conventional stator coil assembly 9 which can be used in place of the aforementioned motor stator 8, which stator coil Group 9 includes a substrate 91 and a coil assembly 92.

然而，該定子線圈組9之各佈線層921必須利用該導接部923予以電性導通，惟各該佈線層921之導接部923係設置於二相鄰線圈922之間；因此，造成該二相鄰線圈922之間必須預留空間，以供容設該導接部923，導致該線圈922之繞線匝數或線徑不易增加，當該定子線圈組9應用於馬達結構時，將影響該馬達之運作效能。However, the wiring layers 921 of the stator coil group 9 must be electrically connected by the guiding portion 923, but the guiding portions 923 of the wiring layers 921 are disposed between the two adjacent coils 922; A space must be reserved between the two adjacent coils 922 for receiving the guiding portion 923, so that the winding number or the wire diameter of the coil 922 is not easily increased. When the stator coil group 9 is applied to the motor structure, Affect the operational efficiency of the motor.
