Abstract

PURPOSE: To determine a motor to be started or stopped by performing overall decision in accordance with the number of motor starts and stops, its operation time, and its excessive winding and load consition in the number of motor units control operation.
CONSTITUTION: When a part of a number of motor groups operates, start or stop is discriminated and it is also discriminated whether the motor is under operation or during stop by externally inputting start or stop command signals in a start or stop discriminator 11 with a pressure switch. An operation time selector 12 inputs timing output signals t1 to tn to time the operation time of each motor and compares its length, then determines the priority so that a motor of which operation time is shortest can obtain the first priority. A start or stop frequency selector 13 inputs signals n1 to nn and selects start frequency in small order and a temperature condition selector 14 inputs output signals td1 to tdn of a temperature detector and selects temperature in low order. Each signal is input to a priority selector 17 and the optimum driving motor is selected.
