Abstract

PURPOSE:To economize energy by cutting the AC power supply to the induction motor at every given period. CONSTITUTION:It consists of a cutting period setting circuit 5 to set a cutting period previously, a counting circuit 6 transmitting output signals every time the cutting value reaches a quantity corresponding to the magnitude of the cutting period display signals entered from the cutting period setting circuit 5 while the number of periodic waves synchronizing to the AC power source 1 being counted, and a cutting command circuit 7 issuing a cutting command to open this switching circuit 3 for a given time space, to the switching circuit 3 based on the output signals from this counting circuit 6. Thereby, the AC power supply to the motor load at every given period is cut, thus, it is feasible to economize energy.
