The invention relates to a ceiling-fan motor, comprising a motor upper shell (3), a motor lower shell (6), a motor shaft (1), an upper bearing (2), a lower bearing (7), a motor stator (4) and a motor rotor (5), wherein the motor rotor (5) is arranged outside the motor stator in a matching mode; the center of the motor upper shell (3) is provided with an upper bearing chamber (31); the upper bearing (2) is positioned in the upper bearing chamber (31) and sleeved on the motor shaft (1); the center of the motor lower shell (6) is provided with a lower bearing chamber (61); the lower bearing (7) is arranged in the lower bearing chamber and sleeved on the motor shaft (1); and the motor rotor (5) is arranged in the inner circles of the motor upper shell (3) and the motor lower shell (6). The ceiling-fan motor is characterized by further comprising a wave-shaped spring gasket ring (8) which is arranged in the lower bearing chamber (61) and positioned at the bottom of the lower bearing (7); the upper bearing (2) is in clearance fit with the upper bearing chamber (31); and the lower bearing (7) is in clearance fit with the lower bearing chamber (61). The upper bearing, the lower bearing and the motor rotor are maintained at proper positions; the radial and axial positioning precision of the upper bearing and the lower bearing is improved; the rotary precision is improved; the vibrationis reduced; and the bearing noise caused by resonance is avoided.
