<p>TITLE: MOTOR FOR USE IN CEILING FAN, AND CEILING FAN A motor for use in a ceiling fan includes a st ationary portion, a rotating portion, and a bearing portion. The stationary portion includes a shaft arranged along a central axis extending in a vertical direction; an armature directly or indirectly fixed to the shaft; and a circuit board arranged to supply power to the armature. The rotating portion includes a rotor holder made up of an upper rotor holder member and a lower rotor holder member, and arranged to cover the armature from above and below; and a rotor magnet or magnets arranged radially opposite the armature, and arranged in an annular shape on an inner circumferential surface of the rotor holder. The bearing portion is arranged to support the rotating portion such that the rotating portion is rotatable with respect to the stationary portion, and includes an upper bearing member arranged between the shaft and the upper rotor holder member on an axially upper side of the armature; and a lower bearing member arranged between the shaft and the lower rotor holder member on an axially lower side of the armature. The circuit board is positioned inside the rotor holder, and is positioned on the axially upper side of the armature. Reference Figure: Fig. 1.</p> |
