摘要： A fan shutter device includes a frame, multiple slats and multiple sleeves. The frame has a first side and a second side, each of which is formed with multiple assembling channels, multiple fixing holes and multiple displacement slots. Each slat has two extension sections and a connection shaft. Each of two ends of the connection shaft is formed with a connection socket. Each sleeve has a pivot pin and a sleeve section. The pivot pin is assembled and connected in the connection socket. Multiple fixing members are respectively passed through the fixing holes to directly fix the sleeves so that the first and second sides are prevented from deforming in assembling process. The slats are spaced from the frame by a gap without abrading with or interfering with the frame. The extension sections are disposed in the displacement slots, which restrict the rotational angle of the slats.

摘要： A fan motor control device includes a zero-crossing detection unit, a phase control unit, an operation processing unit, a first rectifier element and a second rectifier element. The zero-crossing unit generates a synchronization reference signal to the phase control unit, which in turn generates a phase control signal to the operation processing unit. According to the received phase control unit, the operation processing unit generates a motor-starting processing signal to the first and the second rectifier element for driving a fan motor to rotate. Since the phase control unit provides the effect of controlling the fan motor's output power and rotational speed, it enables the fan to have increased rotational speed and provide improved heat dissipation and ventilation effects.
