Fan stator structure
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.
1. A fan stator structure, comprising:
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, the set of insulating supports including an upper and a lower insulating support, the silicon steel sheet lamination being located between the upper and the lower insulating support, the lower insulating support defining a plurality of insulating support holes; and
a plurality of conducting coil end holders, each of which includes a fixing section, a connecting section, and a receiving zone located between the fixing section and the connecting section; the fixing section and the connecting section being located at two opposite ends of the conducting coil end holder, and the fixing section of each of the plurality of conducting coil end holders being received in a separate one of the plurality of insulating support holes of the lower insulating support of the set of insulating supports; and the receiving zone being configured for receiving a front end and a back end of the coils therein, so that the front and back ends of the coils are in contact with the conducting coil end holders;
wherein each of the conducting coil end holders further includes a projected section sidewardly extended from a position near the connecting section; and the connecting section and the projected section together defining the receiving zone as a recess;
wherein the connecting section of the conducting coil end holder is extending through and electrically connected to a circuit board, the circuit board having a first surface and an opposite second surface, the connecting section being extending from the second surface to the first surface directly and exposing from the first surface, and the projected section being abutted on the second surface of the circuit board that faces toward the silicon steel sheet lamination.
