刈 8892 V. Description of the invention (1) [Fields covered by the present invention] I The field covered by the present invention is the winding method of the traditional inner or outer rotor horse 2 magnetic coils through the "combined type" of the invention. Everywhere, early Λ technology means can separate the motor's exciting coil wire slot seat separately: its neighbor, the winding process of its exciting coil can be used alone.

Equipment (using the drum-type winding machine for manufacturing transformers) is made into a grid. J: ;;; :::: ==: = Combination of structural strength = production *, s 转 Rotary motor is provided as mechanical power * ' The requirements for its operating efficiency and the economics of manufacturing technology are as follows: ΐ 吝 The present invention relates to a "combined motor stator two structure" and the use of raw materials for the purpose of high degree of manufacture, with high mechanical structure strength, ^ 7 Degree and roundness accuracy, inside and outside turn, "Hou Yixin [knowledge technology and its shortcomings]" ,,,, to create a high operating efficiency in the field coil winding problem, because t Most of its manufacturing bottle heads must have relative electrical loading and magnetic loading: 的 Π f operating efficiency, entitled Stator Exciting Coil Amperage Wire Diameter /, Electric Loading = questioning means a higher exciting current To be equal to the size, a higher electric load must have a thicker diameter exciting coil for f than two exciting currents. At the same time, if you want to improve the effective transport of the motor, the two-way exciting current flows through the coil wire. Diameter, so it is necessary to increase the efficiency of 2, and then it is necessary to increase the excitation. The best way to occupy the field coil is to increase the occupancy rate of the magnetic coil by two. However, if you use the 附件 neatly wound wire for the figure of the paper in (Appendix _), as shown in Figure 4 (a),

Description of the invention (2) The slot of the sub-slot must be provided with a winding channel of 2 m / m or more for the winding machine of the inner winding guide needle controlled by the CNC shown in (Annex 2). The inner winding type guide pin enters and exits the stator tooth slot to complete the neat winding of the in-line cable. '(Annex I) Figure 2' Figure 4 (a) The slot must be reserved for more than 2 m / m The winding guide pin channel 'must therefore reduce the winding space of the wire groove, that is, the occupation ratio of the wire groove of the in-line cable can only be increased to about 5 〇 ^ As described in (Annex 1), there is a need to improve this phenomenon. The new manufacturing method is to use the core structure of the stator to manually cut the center position of each wire slot = outside, and make the cutting part have a flexible connection structure, so that the stators are lined up to form each wire slot portal. It is as wide as (Annex 1) The in-line cable in the second embodiment of Figure 3, but the above method is because the tooth end of the wire slot is wider than the tooth root, so the insulated wire slot seat cannot be knotted outside beforehand. Sleeve into the root end of the tooth, but must be a row of wire groove tooth root end as shown in (Attachment 1) Figure 3 The insulation project is as shown in (Appendix 1) gq? ^, Which uses three guide pins to carry out the winding process of the field coil with a CN ^ device / step winding, to reduce red; The volume ratio is about 8 Q%. (The "work" of the two types of in-line cables described above after the combination of accessories ^ ° 卩: pieces: as described in the text, so that machinery with a CNC device must be used to stimulate; ： Two, two, and two elephants' all must be punched out, and the internal engineering of the winding and winding guide pin guided by CNC machinery is shown in (Annex II), ，,， = Consider this—the system of winding machinery 1.

Therefore, the accuracy and system of the Yao line fixture is 2 because the high-precision CNC control is difficult and the operation is difficult. Personnel's 508892 V. Description of the invention (3) The quality must be mentioned two. 3 · The cost of the winding is high 4 · Mechanical operation pm) 5 · Because the winding of the C station is indirect, the cost of the motor is increased as a result of the above. Wire-to-wire type, with more materials [The present invention takes into account the occupation of magnetic coils, so the overall production efficiency becomes The modular monovalent horse guide needle winding machine shall Tinan linear low 'resulting in easy and cost-diameter culture salaries and thickness will be governed by the size of the machine increase amount. Controlling the winding speed of the winding guide pin will cause the production efficiency to be too low. The precision of the NC precision winding machine is about 600,000 yuan, which should be the manufacturing cost of the motor. According to US Patent 5,729,072, a CNC and stator must be used. After the combination, the strength of the mechanical structure of the concentricity can not improve the wire groove excitation line. Purpose] It is known that the direct investment of the stator of the motor increases the investment cost of the horse winding machine so that it is very low. In accordance with the above-mentioned large number of Sunda stator parts, the expensive cost of winding coils and exciting coils, and the mechanical limitations of the solution, caused the degree of mechanical equipment to be too slow (60 ~ 800 r 〇 equipment investment costs are very high (1 to 1 〇 000,000 yuan), so it will be increased. ^ '583,387 and other patent cases, the winding mechanism and the accuracy of ^ roundness caused by the machinery of the device are also poor, and many other problems, the second is the occupation rate of miscellaneous circles, And it will consume more cables and lines to improve the effective operating efficiency in the trunking, but it is greatly increased, and the winding connection reflects the economic benefits of the production of each motor. According to the present invention, the CNC machinery controls the winding method. Formula completely eliminates and disproportionately low production

The pre-transformer drum winding machine and equipment can be used for winding production with high production efficiency. Investment, further mechanical energy can be carried out in the form of coaxial multi-connected winding. The rate of exciting coils on the insulated wire slot seat can be greatly increased. Compressor winding manufacturing technology is further developed; furthermore, due to the indexing arrangement of the stator part of the present invention, such as the pressing arrangement of the stator part (such as the application of the seventh figure and the second south efficiency), considerable material can be saved to ensure the concentricity of the overall stator part and Roundness strength.
