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 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.

摘要： A power tool includes a battery pack, a motor, a switching element, a detecting circuit, and a protecting circuit. The battery pack includes a battery. The motor is driven with an electrical power supplied from the battery pack. The switching element is provided between the battery pack and the motor to selectively allow the electrical power to be supplied to the motor when the switching element is turned on and prevent the electrical power from being supplied to the motor when the switching element is turned off. The detecting circuit detects an operating voltage of the switching element. The protecting circuit turns off the switching element when the operating voltage detected by the detecting circuit drops below a first voltage.
