摘要：An energy-efficient electric screw driver equipped with MCU, and has threeadjustment modes, including: Sport, Normal and ECO. Meanwhile, the capacitor ismounted in the control panel of the electric screw driver and is combined with the
battery for use. MCU can limit and change current at different torsions and startupcurrent when the rotating speed is constant. The battery current output can becontrolled. At different modes, the power saving effect can be achieved. Lower currentalso reduces battery temperature, saves power and prolongs battery life.
