  • Patent number: 8241017
    Abstract: A ceiling fan includes a motor for rotating multiple blades. This motor includes a hollow shaft that is disposed upright on the center of a disc-like stator, and a rotor around an outer periphery of the stator. The rotor integrally rotates with the blades. This motor further includes a cylindrical bearing housing, and a pair of ball bearings including an upper ball bearing and a lower ball bearing housed in this bearing housing. This bearing housing has a base in its center. The upper ball bearing is disposed over the base, and the lower ball bearing is disposed under the base in this bearing housing. Both bearings are fixed onto the hollow shaft.
