Ceiling Fan Controller Using a Dip Switch to Set Rotation Speed Thereof

Abstract

A ceiling fan controller using a DIP switch to set a rotation speed comprises a rectifying filter circuit, a CPU, a motor driving module, a voltage lowering circuit, an automatic balancing circuit, and a sensing circuit for a DC non carbon brush motor. A DIP switch electrically connects to the CPU to set different maximum rotation speeds for the DC non carbon brush motor.

1 . A ceiling fan controller using a DIP switch to set a rotation speed comprising a rectifying filter circuit, a central processing unit (CPU), a motor driving module, a voltage lowering circuit, an automatic balancing circuit, and a sensing circuit of a DC non carbon brush motor, characterized in that a DIP switch electrically connects to the CPU to set different maximum rotation speeds for the DC non carbon brush motor, thereby matching different loads of the ceiling fan. 
     
     
         2 . The ceiling fan controller using a DIP switch to set a rotation speed according to  claim 1 , wherein the difference between the new maximum rotation speed and the default minimum rotation speed is divided in equal interval into several speeds after the DIP switch sets the maximum rotation speed of the DC non carbon brush motor.
