摘要： Tightening torque is appropriately managed by a simple means. An electric rotating tool (40) has a brushless DC motor (2), an inverter circuit part (3), and a control circuit part (4). The control circuit part (4) has a current detecting circuit (18), which detects a motor current I, a rotation number detecting circuit (17), which detects the number of rotations of the motor (N), and a computing part (19), which calculates first tightening torque (T1) based on the detection information of the motor current (I) and calculates second tightening torque (T2) based on the number of rotations of the motor (N). The computing part (19) estimates tightening torque Tave based on the estimate value of the first tightening torque (T1) or the second tightening torque (T2). The computing part (19) stops driving the motor (2) when the estimated tightening torque Tave exceeds a set value Tset.

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 rotationally driven in forward and reverse directions by the motor. The anvil is rotated upon striking the hammer 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 alternately supplies to the motor a forward electric power and a reverse electric power in a first cycle. The control unit controls the power supply unit 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 increases to a prescribed value.
