Patents by Inventor Yeh-Chih Lu

Yeh-Chih Lu has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11894735
    Abstract: 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.

  • Publication number: 20220115928
    Abstract: A fan stator structure includes a silicon steel sheet lamination formed of a plurality of laminated silicon steel sheets located between a set of insulating supports and having coils wound thereon; and a plurality of conducting coil end holders respectively including a fixing section and a connecting section, and a receiving zone located between the two sections. The fixing and the connecting section are located at two opposite ends of the conducting coil end holder, and the fixing section is connected to the set of insulating supports. The receiving zone is configured for receiving a front and a back end of the coils, so that the front and back ends of the coils are in contact with the conducting coil end holders. With the conducting coil end holders, the fan stator structure can be manufactured with simplified procedures, reduced time and labor costs, and upgraded good yield rate.
