Abstract
A fastener driving tool is provided with a plunger, an impact spring, a motor, a drive mechanism, a motor drive control unit, a position detection unit, and a timer unit. The drive mechanism moves the plunger from a stop position to top dead center by rotation of the motor. The impact spring moves the plunger in a driving direction. The position detection unit detects that the plunger has reached a predetermined position by the rotation of the motor, and the timer unit measures time therebetween. The motor drive control unit, after power supply to the motor is cut off, performs a stop control for stopping the motor at the predetermined stop position based on the time measured by the timer unit.
