摘要： An impact tool includes a motor, a hammer, an anvil, and a control unit. The hammer is configured to be driven by the motor and be movable in an axial direction of the motor. The anvil is configured to be struck by the hammer. The control unit is configured to control a rotation of the motor. The impact tool further includes a restricting unit configured to restrict the movement of the hammer in the axial direction. The control unit is configured to select a driving mode of the motor between a first mode and a second mode. The control unit selects the first mode when a load of the motor is less than or equal to a prescribed value regardless of a restriction of the restricting unit, whereas the control unit selects the second mode when the load exceeds the prescribe value and the restricting unit restricts the movement of the hammer.

摘要： An electronic pulse driver (1) includes a motor (3), a hammer (4), an anvil (5), an end tool mounting unit (51), a power supply unit (24), and a control unit (72). The hammer (4) is rotationally driven in forward and reverse directions by the motor (3). The anvil (5) is rotated upon striking the hammer (4) 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 (24) alternately supplies to the motor (3) a forward electric power and a reverse electric power in a first cycle. The control unit (72) controls the power supply unit (24) 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 (3) increases to a prescribed value.
