ABSTRACT:
A wireless signal transmission device for a DC brushless ceiling fan motor that includes a wireless signal transmission device to receive and transmit a signal to a controlling unit, and the controlling unit transmits the control signal to the motor via an electric wire. A wireless signal-transmitting device is installed above the motor. The signal-transmitting device detects the position of the motor and transmits a wireless signal to a signal receiving device, which then transmits the signal to the controlling unit, which further transmits the controlling signal to the motor via of the electric wire, for the purpose of controlling the rotation of the motor. Due to the fact that the signal is transmitted wirelessly, it is not necessary to use any destructive process such as drilling a hole on the body of the ceiling fan, and thus the rigidity and the strength of the components are preserved.
