Patent ID: 8497610

Claim:
A ceiling fan motor comprising a motor axle, a stator and a rotor; wherein the stator includes a predetermined number of silicate steel plates stacked on the motor axle, the rotor is pivotally installed on the motor axle of the stator and has a predetermined sensing magnets surrounding the stator, and the ceiling fan motor is further characterized in that: the stator has a plurality of coil arms disposed at interval for the winding of magnetizing coils, a magnetic pole spacer is formed between each pair of adjacent coil arms, a supporting base is provided in a predetermined magnetic pole spacer for accommodating a sensor that detects the positions of the sensing magnets of the rotor, and the rotor consists of an upper shell, a lower shell, and a predetermined number of sensing magnets; the upper shell has a downward-extending annular wall, the bottom of which is provided with a connecting ring; the sensing magnets are fixed on the inner wall of the annular wall and correspondingly around the stator; the edge of the lower shell extends outward to form a connecting part correspondingly connecting to the connecting ring of the upper shell; and a plurality of locking elements go through the connecting ring of the upper shell and the connecting part of the lower shell, thereby connecting the upper and lower shells.
