Abstract
PURPOSE: To enhance speed performance by continuing the operational condition of one of a plurality of motors and switching the other motor to stop at the time when the values of the operating currents of a plurality of motors are decreased below a specified value.
CONSTITUTION: A ceiling crane is moved by 2 motors 5 and 6. The motors 5 and 6 are operated in varying ratios associated with the set-up of the combination of opening and closing of secondary acceleration contactors 8∼10 and 12∼14 as directed by handling instructions of a controller and secondary resistors 7 and 11. Switching contactors 3 and 4 and a current relay 15 are provided so that they are linked together. When one motor is stopped, the other switching contactor is cut out by sensed result of the current relay 15. When the acceleration by the motors 5 and 6 has been completed, switching to one-motor operation is automatically made. Therefore, driving energy can be saved, frequencies of using 2 motors are balanced, and the speed-control performance can be enhanced.
