Manufacturing method of fan stator structure
A manufacturing method of fan stator structure includes the steps of providing a fan stator; providing a plurality of coil lead wire holders at an end of the fan stator; and winding lead wires on the fan stator to form coils, and setting and connecting a front end and a back end of each of the lead wires to the coil lead wire holders. The above method eliminates the drawbacks of the conventional fan stator coil winding operation, such as requiring manual twisting and trimming of the lead wire front ends and back ends and leaking of tin solder occurred during welding of the lead wires to a circuit board.
1. A manufacturing method of a fan stator structure, the method comprising steps of:
providing a fan stator;
providing a plurality of coil lead wire holders at an end of the fan stator, each of the coil lead wire holders including an inserting end, a receiving recess section and a fixing end; the inserting end and the fixing end being located at two opposite ends of the coil lead wire holders; and the receiving recess section being provided near the inserting end on at least one side thereof and located lower than the inserting end;
winding lead wires on the fan stator to form coils; and electrically connecting the front end and the back end of each of the lead wires to the coil lead wire holders at the end of the fan stator.
2. The method as claimed in claim 1 , wherein the providing of the fan stator further comprises laminating a plurality of silicon steel sheets to form a laminated silicon steel core, forming insulation supports at an upper and lower end of the laminated silicon steel core, and locating the coil lead holders on the insulating supports.
3. The method as claimed in claim 1 , further comprising welding joints between the coil lead wire holders and the coils following the winding lead wires on the fan stator.
4. The method as claimed in claim 3 , wherein, in the welding step, the welding is selected from the group consisting of a resistance welding and a laser welding.
5. The method as claimed in claim 1 , further comprising fixing and electrically connecting the coil lead wire holders of the fan stator to a circuit board following the winding lead wires on the fan stator.
6. The method as claimed in claim 5 , wherein the fixing and electrically connecting includes fixing by electrically connecting the coil lead wire holders to the circuit board in a manner selected from the group consisting of a welding manner and a tight fit manner.
7. The method as claimed in claim 1 , wherein the coil lead wire holders have a solder layer applied to surfaces of the coil lead wire holders.
