度制御装置。 This is a device that controls the speed of the fan drive motor installed in a range hood.It inputs a signal modulated in pulse width by a pulse generation circuit to the base of the transistor, and turns on the primary side of the photothyristor.
Turn OFF and turn photo try-attack ON-OFF
When it is turned on, a current is passed through the gate of the triax to turn it on, and the speed of the motor is changed according to the change in the ON time. A stepless speed control device for a motor in a range hood, characterized in that the trigger phase is always set to zero when the load current is ON.
