Abstract

PURPOSE:To reduce a voltage drop in starting and diminish the capacity of a power source, by sequentially starting a plurality of motors when power is restored after power failure during the operation of the motors. CONSTITUTION:When power is restored after power failure during the operation of a plurality of motors, a voltage relay E is energized and a contact ea is closed and a timer T1 is energized. After a prescribed time, a timing contact t1 is closed, a relay Y1 is energized and a contact Ya1 is closed. As a result, contacts ga1, ya1 coupled in parallel with a contact xb1 are both closed, a contact eb1 is also closed and a relay X1 is energized to drive a motor M1. When a contact xf1 is closed by the energization of the relay X1, a timer T2 is energized. After a prescribed limit time, a contact t2 is closed and a relay Y2 is energized. As a result, a contact ya2 is closed and a relay X2 is energized to drive a motor M2. The other motors are also sequentially driven in the same manner.
