Abstract
PURPOSE: To prevent shorts due to the simultaneous continuity of semiconductors for positive and reverse revolution in the case when changing over positive or reverse sides, by installing transistors for interlocking transistors for positive and reverse revolution.
CONSTITUTION: When a positive-revolution signal contact F is closed, a condenser C11 is charged while a transistor Q11 for positive revolution is ON, and semiconductor elements F1, F2 for positive revolution are energized, thus operating an alternating current motor M in positive revolution. Interlock signals flow through a diode D14 at the same time, and a transistor Q21 for reverse revolution does not function by means of a transistor Q22 for reverse revolution interlocking even if a reverse-revolution signal contact R is closed. When the contact F is opened and the contact R is closed, the C11 is discharged, and the Q22 works during a discharge period to lock the Q21. And the Q22 is OFF, the transistor Q21 for reverse revolution is ON, and semiconductor elements for reverse revolution R1, R2 are energized, thus reversing the motor M. In this case, a transistor Q12 for positive revolution interlocking locks the Q11. Thus, shorts due to simultaneous continuity can be prevented.
