Patent ID: 8314523

Claim:
A fixing structure for the sensor of a ceiling fan motor having a motor axle, a stator fixed on the motor axle, and a rotor, pivotally mounted on the motor axle and around the stator, consisting of a predetermined number of silicon steel sheets stacked on the motor axle, the rotor having a predetermined number of sensing magnets, and the sensing magnets being disposed around the stator; the stator having a plurality of coil arms, separated from each other in equal spacing, for field coils to wind around, a magnetic pole spacer being formed between two adjacent coil arms, a magnetic pole spacer having a supporting base for accommodating a sensor for detecting positions of the sensing magnets on the rotor, wherein the magnetic pole spacer accommodates a U-shaped insulating plate with an opening end and a supporting base, the opening end of the insulating plate forms two opposite pinching arms, the supporting base is formed by the two opposite pinching arms at the opening end of the insulating plate, and the sensor is embedded in the supporting base.
