Description of the Invention: The present invention relates to a motor stator and a coil assembly thereof, and more particularly to a motor stator and a coil thereof capable of reducing the overall axial height and reducing the volume. [Prior Art] Please refer to As shown in FIG. 2 and FIG. 2, the more common motor stator 8 is disclosed. The motor stator S generally includes a plurality of silicon steel sheets 8 丨, two insulating sleeves 82 and a coil group 83. The plurality of stone slabs 8 具有 each have a ring body 8 丨丨:====, and after each of the cascading patterns are combined with each other, the two insulating sleeves and the two steel sheets 81 are made of a steel sheet 81 The two ends, and the 砵 _ 82 can be respectively coupled to the plurality of extensions 820 of the support arm 812 of the 矽 kiss-insulation sleeve 8 . Z is also provided with a plurality of coils 831 corresponding to each other. In addition, the coil group 83 is wound around the cymbal sheet 8 by a predetermined number of extensions 82 to form the motor & '8' and the insulating sleeve 82. Currently common on the market:::. Designed for R&D's only the customary Majian has gradually formed towards the miniaturized steel cutting piece 81. Therefore, 8 is mainly composed of the number of mutual stackings, and the conventional motor stator 8 is still difficult/not easy. The overall axial height is lowered; the silicon steel sheet 81 and the coil assembly are designed by the insulating sleeve 82 to protect the coil group 83 from being insulated, and the effect is The volume coughing insulation sleeve 82 of the motor stator 8 also causes an increase in the height. In addition, the coil group 201103234 83 must be wound around the respective support arms 812 of the silicon steel sheet 81 and the extension portions 821 of the insulating sleeve 82 by a predetermined number of turns. A plurality of coils 831, which in turn will further increase the axial height of the motor stator 8. Overall, when the motor stator 8 is applied to the motor structure as shown in Fig. 2, the overall volume and axial height of the motor structure cannot be effectively reduced, resulting in the motor being unable to achieve miniaturization. Referring to FIG. 3, another conventional motor stator 9 is disclosed. The motor stator 9 includes a substrate 9 and a coil assembly 92. The coil assembly 92 is composed of a plurality of coils 921.

However, the coil set 92 of the other conventional motor stator 9 is limited to a specific portion of the surface of the substrate 91, and the coils 921 of the coil group 92 protrude from the surface of the substrate 91. The substrate 91 and the coil assembly 92 of the conventional motor stator 9 still form a certain axial height, which makes it difficult for the conventional heat dissipation fan 9 to further reduce the overall axial height, and can also be designed to be lighter, thinner and shorter. The feasibility of the process.
