摘要： An electronic pulse driver includes a motor, a hammer, an anvil, an end tool mounting unit, a power supply unit, a temperature detecting unit, and a controller. The hammer is drivingly rotatable in forward and reverse directions by the motor. The anvil is provided separately from the hammer and rotated upon striking of the hammer. The power supply unit 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 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.
