Abstract
A motor of a ceiling fan includes a support unit, a rotor unit, a first bearing, a supporting bearing and a stator unit. The support unit has a shaft. The rotor unit has a rotational connecting member. The rotational connecting member includes a central hole through which the shaft extends, as well as an inner flange extending inwardly of the central hole. The first bearing includes an inner race fit around the shaft and an outer race connected to an inner periphery of the rotational connecting member. The inner and outer races are spaced from each other in a radial direction perpendicular to the shaft. The supporting bearing includes a fixed race fit around the shaft and a rotational race abutting with the inner flange. The fixed race and the rotational race are spaced from each other in an axial direction. The stator unit is connected to the support unit.
