摘要： An impact power tool includes an impact mechanism for applying a striking impact to an output shaft by using an output power of a motor. A strike detection unit detects the striking impact applied by the impact mechanism to obtain a striking timing and a striking speed detection unit calculates a striking speed from the striking timing obtained by the strike detection unit and a rotation angle of the motor obtained by a rotation angle detection unit. A control unit counts the number of striking impact detected by the strike detection unit and stops the motor if the number of striking impact reaches a predetermined strike number. The control unit is designed to correct the predetermined strike number when the striking speed obtained in the striking speed detection unit is equal to or lower than a specified striking speed.

摘要： A impact power tool includes a motor rotating a drive shaft, an output shaft holding a tool bit, and a hammer coupled to the drive shaft. The hammer is rotatable together with the drive shaft and is engageable with an anvil fixed to the output shaft so as to give a rotary impact to the output shaft. The tool includes a speed commander generating a target speed intended by a user, and a speed detector for detection of a speed of the drive shaft. A speed controller generates a control signal for driving the motor by referring to the target speed and the detected speed. The speed controller provides a detection time frame, and to adopt a predefined pseudo-detection speed as a substitute for the detected speed when no speed detection is available within the detection time frame. Accordingly, even if no speed detection continues, i.e., the motor is stalled over the detection time frame, the speed controller can successfully generate the control signal by making the use of the pseudo-detection speed, thereby continuing to rotate the drive shaft for generating the impact regularly and consistently without causing a delay.

摘要： An electric power tool includes a motor; a battery unit for supplying an electric power for driving the motor; a driving force transmission mechanism for transmitting a driving force of the motor; a manipulation unit for receiving input data including a rotation number and an on/off manipulation of the motor; a motor control unit for controlling the motor based on the input data from the manipulation unit; and a temperature sensor for detecting a temperature of the battery unit as a temperature value. If the temperature value detected by the temperature sensor while being operated in an normal operation mode is higher than or equal to a first abnormal temperature value, the motor control unit determines that the battery unit is in an abnormal state, and converts an operation mode of the motor to a limited operation mode in which a rotation of the motor is stopped or suppressed.

摘要： In a power fastening tool for fastening a fastening member such as a screw or a fastening member, malfunction that driving of a motor is stopped before the fastening member is fastened completely can be prevented. A fastening judger judges that the fastening operation is completed when a value of an estimated torque T for fastening the fastening member becomes larger than a predetermined lower limit value T1 previously set by a user and a value of a torque variation ratio ΔΔT varies from positive to negative. Thus, it is possible to prevent malfunction for stopping driving of a motor even when the value of the torque variation ratio ΔΔT varies from positive to negative due to trouble before the vale of the estimated torque T becomes larger than the lower limit value T1.
