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: An electric work machine (2) includes a motor (M) and a control unit (36) that controls rotation of the motor. The control unit (36) is configured such that an operating mode is switchable between a normal mode, in which the motor is rotated within a prescribed output range, and a power mode, in which the motor is rotatable with energy greater than in the normal mode. Furthermore, the control unit (36) is configured to restrict use of the power mode.

Abstract: A rotary impact tool according to one aspect of the present invention includes a motor, an impact mechanism, a drive unit, an impact detection unit, and a control unit. The control unit reduces a driving force for the motor caused by the drive unit when a count of impacts detected by the impact detection unit has reached a determination count set in advance, which is a value greater than one.

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.

Abstract: A hand-held electric power tool includes a main power SW provided in a motor housing, a trigger SW provided in a grip portion that protrudes from the motor housing, and a controller. The controller switches an operation mode to one of a drive enabled mode in which driving of the motor is enabled and a drive disabled mode in which driving of the motor is disabled, in accordance with a switching command from the main power SW. In the drive enabled mode, driving of the motor is controlled in accordance with a driving command input from the trigger SW. The controller switches the operation mode to the drive disabled mode in response to the driving of the motor being stopped due to stopping input of the drive command from the trigger SW.
