Abstract: An electric work machine in one aspect of the present disclosure includes a motor, a manual switch, and a control circuit. The control circuit switches a preset control either to be enabled or disabled. During the preset control being enabled, the control circuit (i) varies an actual rotational speed of the motor in accordance with an actual moved distance of the manual switch and (ii) increases the actual rotational speed in response to a load being imposed on the motor. During the preset control being disabled, the control circuit varies the actual rotational speed in accordance with the actual moved distance of the manual switch in a manner at least partly distinctive from a variation in the actual rotational speed during the preset control being enabled.

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: An electric working machine in one aspect of the present disclosure includes a motor, a controller, and a setter. The controller is configured to change a rotational state of the motor, in response to an establishment of a condition for change after the motor is initiated, from a low speed rotation to a high speed rotation. The setter is configured to set, based on a situation in the motor in the low speed rotation, a control variable of the motor in the high speed rotation and/or the condition for change.

Abstract: An electric power tool in one aspect of the present disclosure comprises a motor, a hitting mechanism, a hitting detector, and a control unit. The control unit is configured to set a control amount of the motor so that the motor rotates at a lower speed than a speed in the target rotation state during an initial driving period, and switch the control amount to a final control amount corresponding to the target rotation state when the initial driving period elapses. The initial driving period is a period from when generation of a hitting force is detected by the hitting detector until a predetermined first time period elapses, after the motor is started driven.
