Usually, fluid or fuel supply device need space to need special sensor to control motor, attaches with ancillary equipment to attach sensor. Also, difficult point follows need signal line and other circuit etc. In this paper, used that proposed control system that use hall sensor to solve discomfort and problem and difference control principle of system happens in current flow according to motor action step. Also, could reduce breakdown by sensor establishment, reduce material costs and personnel expenses as well as control system superior. Auto-pumping system sees that will can apply, develop several kind of device that use system hereafter to all fluid supply systems through soft-ware adaptation.
