    Abstract: 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.

    Abstract: The present invention provides a power tool for tightening a fastener. The power tool includes a motor, a hammer, an anvil, and a control unit. The hammer is intermittently or continuously rotatable in a forward direction by the motor. The anvil is impacted by the hammer rotated in the forward direction. The control unit controls the hammer to continuously rotate at a first number of rotations, and to intermittently rotate at a second number of rotations lower than the first number of rotations when a prescribed time has elapsed from the rotation of the hammer at the first number of rotations, and then to intermittently rotate at a third number of rotations lower than the second number of rotations when a predetermined time has elapsed from the rotation of the hammer at the second number of rotations.

    Abstract: 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 rotatable together with the anvil. The end tool mounting unit transmits the rotation of the anvil to an end tool. The power supply unit supplies a drive electric power to the motor. The control unit controls the power supply unit to halt a supply of the drive electric power to the motor when an electric current flowing to the motor increases to a prescribed value. The control unit controls the power supply unit to supply to the motor a prestart electric power lower than the drive electric power before supplying the drive electric power in order to permit the power supply unit to supply the drive electric power after the hammer is in contact with the anvil.
