Abstract
An electric work machine (), such as a power tool, includes a motor () having a rotor, a drive part () that supplies electric currents to drive the motor, a rotational-direction selection part (), and a motor-control part (). 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.
