Patent ID: 7786692

Claim:
A signal transmission apparatus of a DC brushless motor for a ceiling fan, being electrically connected to the DC brushless motor of the ceiling fan and a controller, the DC brushless motor comprising a plurality of magnetic poles and at least one sensor, the controller comprising a signal restorer, the signal transmission apparatus comprising: a transmission line; a reference level line for providing a reference voltage level; and a signal processor; wherein each of the at least one sensor is configured to sense variation of operation of the magnetic poles of the DC brushless motor, and generate at least one output signal, the signal processor configured to receive and process the at least one output signal into a sequenced signal, the sequenced signal in which the at least one output signal is being transmitted to the controller via the transmission line, the signal restorer configured to receive and restore the sequenced signal to the at least one output signal, and the controller configured to control the DC brushless motor to operate according to the restored at least one output signal.
