As shown in the figure, in addition to the speed adjustment, the controller can repeat the start and repeat the timing operation after the preset timing time. The controller is composed of a speed regulating choke, a step-down rectifier circuit, and timing control.
The control mode of the electric fan is divided into three types: straight through, intermittent and timing. In the intermittent state, 555 and R2, R3, RP1 and C2, and R7, C3, etc. constitute an astable multivibrator. In the timing state, 555 is connected to a single stable circuit, and the timing charge and discharge time constant is determined by R2~6, RP1 and C2.
