Abstract

PURPOSE:To permit variable speed control of a motor by eliminating necesity of a reactor variable speed tap, by composing a control circuit of a triac and an instable multi-vibrator which controls the triac. CONSTITUTION:A triac TC, which controls passing of current to a motor FM by repeating turn-on and turn-off motion, and instable multi-vibrators (Q1 and Q2, etc.), which are capable of controlling turn-on and turn-off motions of this triac TC and of setting length of time of turn-on and turn-off motions within a range of several cycles of power source frequency, are provided. By varying resistance value of a variable resistance VR, length of time of turn-on and turn-off motions of the truansistor Q2, that is, length of time of turn-on and turn-off motions of the triac TC, is changed. In other words, setting is made in such a manner that the transistor Q2 is continuously turned on for operating when wind is strong, the transistor Q2 is turn on for 1.5/60sec and off for 0.5/60sec repeatedly for operating when wind is medium, and the transistor Q2 is turned on for 1/60sec and off for 1/60sec repeatedly.
