Description of the invention: [Technical field to which the invention pertains] The present invention relates to a motor stator structure and a method of manufacturing the same, and more particularly to a structure for manufacturing a motor stator with a silicon steel sheet and a method for manufacturing the stator thereof, which can lift the motor Performance and reduce magnetic loss and iron loss. [Prior Art] According to the motor, the motor is widely used and widely used. It is mainly composed of a stator and a rotor. The stator can be a toroidal core (commonly called an electromagnet) wound around a coil, covering the rotor, and the rotor is a magnet. The electromagnetic field causes the rotor to rotate in the center of the stator, but conversely, the stator is a magnet and the rotor is an electromagnet. According to the application of the motor, it can be divided into a speed control type motor and a precision control motor. The speed control type motor is relatively simple and can control the rotation speed of the motor. The precision control type motor can not only control the rotation speed of the motor, but also control The angle (or position) at which the motor rotates, such as a stepper motor or servo motor. The rotation angle of the motor rotation is determined by the electromagnetic polarity generated by the stator. Figure 1 is a perspective view of a stator of a conventional servo motor, and Figure 2 is a perspective view of a stator of a conventional stepping motor. The servo motor produces nine levels (groups) of electromagnetic fields, while the stepper motor of Figure 2 can have up to sixteen (group) electromagnetic fields. As shown in Fig. 1, the structure of the motor stator is composed of a yoke core, nine sets of tooth cores and nine sets of winding grooves. The core of the car is hollow and the inner part of the 201006101 is formed into a nine-corner shape. The core of the tooth is in the shape of τ. The winding wire is wound around the wire slot and then inserted into the tooth core, and then assembled into the yoke core. The components are numerous and complicated in structure, but the advantage is that the winding is easy. Further, as shown in FIG. 2, the structure of the motor stator is composed of a plurality of silicon steel sheets which are overlapped and formed by integral stamping. The advantage is that the structure is simple, and the disadvantage is that the winding is difficult, and a special winding machine is needed. Moreover, the mold for stamping the silicon steel sheet has high precision and high cost, so the manufacturing cost is quite high. ® As can be seen from Figure 1 and Figure 2, the motor stators are composed of stacks of silicon steel sheets. The motor stator consisting of silicon steel sheets has the highest efficiency, the least magnetic loss and the iron loss, so it is used by the precision motor manufacturing industry. . However, in order to connect the combined silicon steel sheets, it is necessary to additionally weld the steel sheets by laser, or punch out the bumps on each of the steel sheets to be combined with each other, and laser welding is required to separately purchase a laser machine, which is expensive, and The bump point is connected to the silicon steel sheet, which will affect the electromagnetic field on the silicon steel sheet, causing magnetic loss and eddy current loss. ® In addition, the domestic invention patent No. 1288518 is a modified patent of a conventional stator, as shown in Fig. 3 is a schematic view of a planar structure. The stator of the patent is composed of nine sets of single magnetic poles, which are rounded. The single magnetic pole is a one-piece shaped core, which is not composed of silicon steel sheets. Therefore, it can solve the shortcomings of laser welding or picking up the steel sheet with bumps, but the cost of the core is much higher than that of the steel sheet. Not as good as Dream Steel. The above-mentioned conventional motor stator has advantages in structure or material, but 201006101 also has shortcomings to be overcome. Therefore, the hair shape of the case (4) - the structure and manufacturing method of Shixia steel sheet = horse nucleus can overcome the conventional knowledge. The motor has a shortcoming in the structure and process' while retaining all the advantages. [Summary of the Invention] The purpose of this month is to provide the "state ❹ stator structure, the system of conversion, the structure is simple, the material cost is low, the mold cost is low, and the advantages of automatic mass production are To achieve the above object, the main technical feature of the present invention is to provide a method for manufacturing a horse, the steps comprising: first punching a plurality of steel cutting sheets to form a plurality of plastic monopolar sheets, and then consisting of a plurality of stacked monopolar sheets a plurality of work-type monopole strips, followed by gluing and bonding the work-type monopole strips, and then winding the coils on each of the work-type monopole strips, and then enclosing the work-type military strips into a circle, and finally Glue to form the stator. In order to achieve the above object, the second technical feature of the present invention is to provide a motor stator structure, which is a plurality of monolithic sheets made of a plurality of patches, which are stacked to form a plurality of monolithic strips and then glued together. a coil is wound on the single-pole strip, and the coil is formed into a circle to form a post-sleeve adhesive. The work-type monopole sheet and the stacked monopole strip are formed into a long surface and A short surface, which is slightly guillotine, and has a short facing inner circumference to form a 201006101 circular shape; a positioning flange is formed on one side end surface of the long surface, and a positioning groove is formed on the other end surface, so that two and two types are formed When the monopole strips are combined, the positioning flange of one of the working monopole strips can be accommodated in the positioning groove of the other type of strips, so that the monolithic strips can be accurately positioned to form a circle. shape. [Embodiment] In order to enable the reviewing committee to better understand the techniques, means, and effects of the present invention for achieving the intended purpose, refer to the following detailed description of the invention and the accompanying drawings, The features and features of the invention are to be understood as being limited and not limited by the description.凊 Refer to FIG. 4, which is a three-dimensional schematic diagram of a monopolar strip composed of a monolithic sheet of the invention. The manufacturing process of the motor stator of the present invention is first formed by stamping a plurality of silicon steel sheets with a precision tooling die to form a plurality of work orders. The pole piece 11 is further stacked into a single-pole strip 12 by a plurality of working monopole sheets 11 , and the invention is coated with a glue on the joint surface of each type of monopole sheet U, and is formed after the glue is dried. This type of monopole strip 12. Then, after winding the coil on each of the work type monopole strips 12, a plurality of stages (groups of electromagnetic poles) are formed, and then the plurality of stages (groups) of the work type monopole strips 12 are rounded to form a stator of the motor. 1〇, as shown in Fig. 5, is a three-dimensional schematic diagram of the stator 1〇 composed of the work type monopole strip 12 of the present invention. After the stator 1〇 is formed, the joint surface of the two joints and the single strip is coated with glue, etc. After drying, a stator 10 of a motor is formed. However, in the present invention, after the adhesive is applied, the adhesive can be quickly dried and fixed by using an oven baking method or an ultraviolet baking method, or the glue can be dried by the natural air drying method 201006101. Since the stator of the motor determines the multi-raise of the electromagnetic pole, and the motor stator of the present invention is completely composed of a silicon steel sheet, the present invention only needs to precisely control the mold of the stamped steel sheet to form the size and shape of the shaped monopole piece u. Then, the number of electromagnetic poles forming the stator of the forming monopole strip 12 can be controlled, and the mold for stamping the rare steel sheet is relatively low in cost because of its simple structure.
