Abstract: A communicator in one aspect of the present disclosure includes a connector, a communication circuit, and a communication controller. The connector is electrically coupled to an electric working machine. The communication circuit performs wireless communication. The communication controller cyclically transmits operational information without specifying a recipient via the communication circuit in response to an operating mode of the communication controller being set to an operation-transmission mode. The operational information indicates an operating state of the electric working machine.

Abstract: An electric power tool includes a motor with a rotor having a permanent magnet; a control unit that sets a control amount of the motor in accordance with operation of an operation portion and that drive-controls the motor based on the control amount; and a number-of-rotations detection unit that detects the number of rotations of the motor. During driving of the motor, when the number of rotations detected by the number-of-rotations detection unit has reached an upper limit number of rotations set in advance, the control unit shifts drive control of the motor to rotation control, in which the control amount is made to be increased or decreased so that the number of rotations of the motor becomes a predetermined target number of rotations.

Abstract: An electric power tool to tighten a screw while drilling a hole with the screw in a tightening-target-object includes a motor as a drive source. A motor control unit controls the motor such that the rotation number of the motor is a rotation number according to specifics of an operation input received by an operation receiving unit with a preset maximum rotation number as an upper limit. At a start-up of the motor, the maximum rotation number is set to a first maximum rotation number. When it is detected that a hole has been drilled in the tightening-target-object with the screw after the start-up of the motor, the maximum rotation number is set to a second maximum rotation number lower than the first maximum rotation number. The second maximum rotation number is set according to a material thickness so as to become lower as the material thickness is smaller.

Abstract: A motor-driven appliance comprises a drive source for driving a tool, a control unit, a power supply unit, a switch unit, a receiving unit, a supply signal output unit, and a data communication unit. The power supply unit generates a control voltage for operating the control unit. The switch unit supplies the control voltage to the control unit and stops supply of the control voltage to the control unit. The control voltage is supplied to the control unit while a given supply signal is inputted to the switch unit. The supply signal output unit outputs, to the switch unit, the supply signal for supplying the control voltage to the control unit when the receiving unit receives the electromagnetic wave while the supply of the control voltage to the control unit is stopped. The data communication unit outputs, to the control unit, the data contained in the electromagnetic wave.

Abstract: A motor-driven appliance includes a motor and a control unit that controls a drive output to the motor. The control unit detects a state amount indicating an operational state of the motor to derive a fluctuation range of fluctuation in the state amount. The control unit detects whether the motor is in an unloaded state or in a loaded state, based on the derived fluctuation range to perform the drive output to the motor, based on the detected result.
