  • Publication number: 20210331305
    Abstract: An electric power tool includes: a motor; an output shaft; and a power transmission mechanism that transmits a rotational output of the motor to the output shaft. A motor control unit controls rotation of the motor in accordance with an on operation of the user operation switch performed by a user. A detector detects physical quantity data while the motor is being rotated. A status determination unit determines whether the electric power tool is in a deteriorated status, by using the physical quantity data. A notification interface communicates that the electric power tool is in a deteriorated status while the motor is not being rotated.

  • Publication number: 20210323125
    Abstract: In an electric power tool, an acquisition unit acquires physical quantity data detected while a motor is being rotated. A storage unit stores the physical quantity data and time information related to time when the physical quantity data is acquired, mapping the physical quantity data and the time information to each other. A transmission unit transmits the physical quantity data and the time information to a server system. The server system includes: a server-side reception unit that receives the physical quantity data and the time information transmitted; and a status evaluation unit that evaluates a level of a status of the electric power tool by using the physical quantity data and the time information.

  • Publication number: 20210252681
    Abstract: An electric power tool includes: an output shaft on which a front-end tool is adapted to be mounted; and a power transmission mechanism that transmits a rotational output of a motor to the output shaft. A posture information acquisition unit acquires posture information for identifying a posture of the electric power tool. A torque information acquisition unit acquires torque information indicating a measured value of tightening torque produced by the front-end tool. A transmission unit transmits the posture information, the torque information, and time information related to a time when respective information is acquired to an external apparatus.
