摘要： A power tool including: a housing configured to support an end bit, a motor accommodated in the housing, a transmission mechanism, a trigger switch, a load judging unit, and a motor stop control unit. The transmission mechanism transmits a rotational force of the motor to the end bit. The trigger switch is configured to switch between instructions to the motor. The instructions include a rotation instruction for providing a rotation state of the motor and a stopping instruction for providing a stopping state of the motor. The load judging unit judges whether or not a load is applied to the end bit during rotation of the motor. The motor stop control unit stops the rotation of the motor irrespective of the instructions of the trigger switch when the load judging unit judges that no load is applied to the end bit and a period of a non-load state exceeds a predetermined time period.

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.

摘要： An electric boring tool comprises an electric motor, a switch trigger, a tip tool driven by driving force of the electric motor, a power transmission mechanism for transmitting the driving force of the electric motor to the tip tool as rotational force and/or hammer force, and a motor control unit for controlling speed of the electric motor in response to an extent of pulling of the switch trigger. The motor control unit subjects the electric motor to low speed control after the electric motor is started up, and controls the speed of the electric motor in response to the extent of pulling of the switch trigger when the load current of the electric motor is set value or greater during the low speed control.
