Patent ID: 7664377

Claim:
An driving apparatus for being applied in a ceiling fan, the ceiling fan comprising a direct current (DC) brushless motor, an axle, and a controller, the driving apparatus being configured between the DC brushless motor and the controller and being electrically connected to the controller, the DC brushless motor comprising a stator and at least one pair of magnetic poles, the driving apparatus comprising: a supporting element, being connected to the DC brushless motor via the axle; at least one coder, each of the at least one coder being set on the shell of the DC brushless motor corresponding to the position of the at least one pair of magnetic poles, each of the at least one coder having a lateral dimension and synchronously rotating with the DC brushless motor; at least one sensor being electrically connected to the controller, the at least one sensor being set on the supporting element corresponding to the position of the stator and between the supporting element and the shell of the DC brushless motor, the at least one sensor being configured to sense the motion of the at least one coder; wherein each of the at least one sensor generates at least one output signal in response to the lateral dimension of the at least one coder, the controller controls operation of the DC brushless motor according to the at least one output signal.
