An energy-efficient electric screw driver equipped with MCU, and has three adjustment modes, including: Sport, Normal and ECO. Meanwhile, the capacitor is mounted 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 startup current when the rotating speed is constant. The battery current output can be controlled. At different modes, the power saving effect can be achieved. Lower current also reduces battery temperature, saves power and prolongs battery life. |
