摘要： An electronic pulse driver includes a motor, a hammer, an anvil, an end tool mounting unit, a power supply unit, and a control unit. The hammer is rotationally driven in forward and reverse directions by the motor. The anvil is rotated upon striking the hammer against the anvil as a result of a rotation of the hammer in the forward direction after rotation of the hammer in the reverse direction for obtaining a distance for acceleration in the forward direction. The power supply unit alternately supplies to the motor a forward electric power and a reverse electric power in a first cycle. The control unit controls the power supply unit to alternately supplies the forward electric power and the reverse electric power in a second cycle shorter than the first cycle when an electric current flowing to the motor increases to a prescribed value.
