Abstract: An electric work machine (1; 110; 120; 130), such as a power tool, includes a motor (11) having a rotor, a drive part (13) that supplies electric currents to drive the motor, a rotational-direction selection part (17), and a motor-control part (14; 31, 32, 40, 50, 60; 14, 40, 60, 73, 80; 14, 60, 91). The rotational-direction selection part is configured for manually setting (selecting) the rotational direction of the rotor and outputs first and second setting signals that each indicate the set (selected) rotational direction. The motor-control part controls the drive part such that the rotor rotates in the rotational direction indicated by the first setting signal and/or the second setting signal. In response to a determination that the rotational directions indicated by the first and second setting signals are inconsistent, the motor-control part stops or prevents the drive of the motor.

Abstract: An electric working machine in one aspect of the present disclosure includes a driving device, a controller, a control power source, and an operation state determiner. The control power source includes a first converter and a second converter. The control power source transitions to a first conversion state when the operation state determiner determines that the controller is in a control operation state. The control power source in the first conversion state supplies a first control current to the controller. The control power source transitions to a second conversion state when the operation state determiner determines that the controller is in a low power operation state. The control power source in the second conversion state (i) stops operation of the first converter, and (ii) supplies a second control current to the controller.

Abstract: A dust collector in one aspect of the present invention comprises a dust collection portion, a communication portion, and an interlock operation control portion. When the communication portion receives an interlock command transmitted from an electric working machine, the interlock operation control portion makes the dust collection portion operate interlocking with the electric working machine. The interlock operation control portion includes a storage portion, in which identification information specific to the electric working machine with which the dust collection portion is to be made to perform the interlock operation is stored.
