Therefore, in the prior art, the industry mostly uses the winding shaft. The plastic injection system is used to bury the two iron rods in the position of the two terminal heads, and then is integrally coated with plastic coating. ..., 20 However, the aforementioned stator structure has some problems. Embedding the iron rod in the plastic injection mold will increase the manufacturing cost of the winding shaft, and since the outer layer of the terminal terminal is made of plastic material, the soldering does not help the heat conduction and the soldering property is extremely poor, so that the coil head of the enameled wire must be Multi-circle vegetation, and each circle must be close together but not overlapped, so that the wire -4-M330678 can form a better thermal conductivity ferrule to improve the soldering result, but the wire diameter of the enameled wire itself Very thin, so when the coil head improves the thermal conductivity, the high temperature during soldering is directly transmitted to the terminal head, which makes the terminal head easily deformed or damaged, and relatively disadvantageously causes the stator. Therefore, there are still some improvements in the basic structure of the conventional skills. [New content] In view of the above-mentioned shortcomings, the creator has painstakingly studied and created a small motor that improves the stator structure. 10 The main purpose of this creation, The utility model relates to a small motor which provides a modified stator structure, which changes the manufacturing process of the stator by modifying the structure of the stator to reduce the production cost of the stator.
