Ceiling fan motor with cooling air channel

A motor of a ceiling fan, comprising:

• a stator having a shaft and a core, wherein the shaft extends in an axial direction;
• a rotor having a first housing rotatably coupling with the shaft, wherein the first housing has a first peripheral portion extending in the axial direction and surrounding the shaft, wherein the first peripheral portion is spaced from the shaft in a radial direction perpendicular to the axial direction;
• and
• a base having a second housing firmly connecting with the stator, wherein the second housing has a second peripheral portion extending in the axial direction and surrounding the shaft, wherein the second peripheral portion is spaced from the shaft in the radial direction and is located radially inward of the first peripheral portion of the first housing,
• wherein the core of the stator is positioned between the first and second housings, wherein an air channel communicates an inside and an outside of the motor, wherein the first peripheral portion of first housing partially overlaps with the second peripheral portion of the second housing in the axial direction and is spaced from the second peripheral portion of the second housing by a gap in the radial direction, wherein the gap communicates the inside and the outside of the motor, wherein the air channel includes the gap, and wherein the first housing is rotatable relative to the second housing for generating an air current inside the motor and guiding the air current out of the motor via the air channel.
