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： A power tool includes: a battery cell group including a plurality of secondary battery cells; a motor to which an electric power is supplied from the battery cell group through a switching element and a trigger switch; a current detector detecting a current value flowing in a current path; and a controller configured to receive a detection signal from the current detector and controls on/off operation of the switching element. If the current detector detects that the current value flowing in the battery cell group continuously exceeds a given value for a first time period, the controller conducts one of alarm display and alarm control for allowing an operator to recognize that a high load operation continues. If the current value continuously exceeds the given value for a second time period longer than the first time period, the controller turns off the switching element to interrupt the current path.

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), a temperature detecting unit, and a controller (72). The hammer (4) is drivingly rotatable in forward and reverse directions by the motor (3). The anvil (5) is provided separately from the hammer and rotated upon striking of the hammer. The power supply unit (24) alternately supplies a forward electric power and a reverse electric power to the motor in a first cycle. The temperature detecting unit is configured to detect a temperature of the motor. The controller (72) is configured to control the power supply unit to alternately supplies the forward electric power and the reverse electric power in a second cycle longer than the first cycle when the temperature of the motor detected by the temperature detecting unit increases to a prescribed value.
