Abstract

A motor of a ceiling fan includes a stator, a shaft, a linking seat, and a rotor. The stator has a core with an assembly hole. The linking seat couples with the core and has an axial hole in alignment with the assembly hole in an axial direction of the shaft firmly resting in the axial hole. The rotor is rotatably arranged around the shaft.

First claim

What is claimed is:

1. A motor of a ceiling fan, comprising:
a stator including a core having an assembly hole, wherein the stator further comprises two insulated bobbins, wherein each of the two insulated bobbins has a first coupling portion, and wherein the two insulated bobbins connect with two opposite sides of the core, respectively;
a shaft;
a linking seat coupled with the core and having as axial hole in alignment with the assembly hole in an axial direction of the shaft firmly resting in the axial hole, wherein the linking seat has a second coupling portion in alignment and coupled with the first coupling portions of the two insulated bobbins to connect the linking seat with the core; and
a rotor rotatably arranged around the shaft.

2. The motor of the ceiling fan as claimed in claim 1 , wherein each of the two insulated bobbins has a passageway, and wherein the assembly hole, the passageways of the two insulated bobbins, and the axial hole of the linking seat align with each other in the axial direction of the shaft for the shaft to pass through.

3. The motor of the ceiling fan as claimed in claim 2 , wherein the passageway of each of the two insulated bobbins has a bore larger than a bore of the axial hole.

4. The motor of the ceiling fan as claimed in claim 2 , wherein a positioning portion surrounds the passageway of each of the two insulated bobbins, extends into the assembly hole of the core, and couples with the core.

5. The motor of the ceiling fan as claimed in claim 1 , wherein each of the first coupling portions of the two insulated bobbins comprises a plurality of through holes, wherein the second coupling portion of the linking seat comprises a plurality of fixing holes aligning with the plurality of through holes, respectively, and wherein a plurality of fixing members passes through the plurality of through holes and the plurality of fixing holes to couple therein.

6. The motor of the ceiling fan as claimed in claim 1 , wherein the stator couples with a base having an aperture, and wherein the linking seat further has an opening communicating with the assembly hole of the core and the aperture of the base.

7. The motor of the ceiling fan as claimed in claim 1 , wherein a bore of the assembly hole is larger than a bore of the axial hole.
