The invention teaches a ceiling fan motor, and specifically, a brushless DC external rotor motor, comprising an electrical control member and a motor structural member, wherein the motor structural member comprises a shaft 1 , a stator 2 , and a rotator 3 , the stator is fit over the shaft 1 , the rotator is fit over the stator 2 , and the stator 3 is engaged with the shaft 1 via a pair of bearings 4 . The rotator 3 comprises a top end cover 5 , a bottom end cover 6 , an outer shell cover ring 7 , and a plurality of magnets 8 , wherein the magnets 8 are positioned along the circumferential direction of the inner wall of the outer shell cover ring 7 . The top end cover 5 and the bottom end cover 6 are installed on the top and bottom of the cover ring 7 , respectively, and are connected to each other by means of a plurality of bolts and nuts. The ceiling fan motor of the invention provides the advantages of efficient energy consumption, low noise, and high operational stability at low speeds.
