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 includes a motor and a controller. The controller is configured to control the motor. Specifically, the controller is configured to operate in at least two modes: a first mode and a second mode. The first mode includes a plurality of stages having different control conditions related to the motor. The second mode includes at least a common stage having control conditions same as those for a specific stage among the plurality of stages of the first mode. The common stage of the second mode starts more quickly than the specific stage of the first mode.

Abstract: A rechargeable electric power tool includes a battery pack that is detachably provided on a housing accommodating a motor and that supplies electric power to the motor, and a tool that is driven by the motor. A standby switch and a lock-on switch are arranged at the housing. The standby switch is able to set the rechargeable electric power tool to a standby state where the rechargeable electric power tool waits for the motor to be driven. The lock-on switch is able to shift the rechargeable electric power tool from the standby state to a state where the motor is driven so as to keep the state where the motor is driven.

Abstract: A variable speed switch includes a switch main body portion which is accommodated in a housing of an electric power tool and mounted to the housing so as to be capable of relative movement, and a load sensor which is provided in the switch main body portion and capable of outputting an electric signal in proportion to the amount of distortion caused by a pressing force. The switch operating portion is mounted on the surface of the housing so as to be capable of relative displacement with respect to the housing and transmits a pressing force applied to the switch operating portion to the load sensor, with the maximum displacement amount of the switch operating portion being set to equal to or less than 5 mm.

Abstract: A rebar tying tool (2; 302; 402) include a feed mechanism (24), which includes a first motor (32; 304) and feeds a wire (W), and a twisting mechanism, which includes a second motor (76; 306) and twists together one or more portions of the wire. A control unit (202; 350) controls the first motor and the second motor and includes a general-purpose I/O port (202c; 350c) and a motor-control-signal output port (202a; 350a). A motor-control-signal output-destination-switching circuit (204; 310; 406) inputs motor-control signals (UH, VH, WH, UL, VL, WL) from the control unit via the motor-control-signal output port and selectively outputs the inputted motor-control signals to either the first motor or the second motor in response to input of a switching signal (SW).
