A ceiling fan motor includes a sleeve, a stator unit fixed around the sleeve, a rotor unit rotatably mounted around the sleeve, and an axle detachably mounted to the sleeve. The axle can include an extending section and a suspension section. The extending section extends through and is coupled to the sleeve. The suspension section is exposed outside of the sleeve. The extending section can be contiguous to the suspension section. An outer diameter of the axle at the extending section can be smaller than an outer diameter at the suspension section to form a shoulder. An end of the sleeve can abut the shoulder.
