摘要： A motor driven appliance in one aspect of embodiments of the present disclosure comprises a light source, a lighting unit, a motor, an operation unit, an operation detector, a reference signal output unit, a determination unit, and a control unit. The operation detector detects that the operation unit is operated, and outputs an operation detection signal that indicates that the operation unit is operated. The reference signal output unit outputs at least one reference signal that can be used as a reference for determining whether the detection by the operation detector is normal. The determination unit determines whether the operation unit is actually operated based on the operation detection signal and the at least one reference signal. The control unit controls operation of the lighting unit based on the determination made by the determination unit.

摘要： In a rotary impact tool according to an aspect of the present disclosure, an impact mechanism rotates an output shaft by a rotational force of a motor and, when a torque equal to or greater than a given value is externally applied to the output shaft in a direction opposite a rotational direction of the output shaft, the impact mechanism intermittently applies an impact force as a momentary torque to the output shaft in the rotational direction of the output shaft. A protection unit stops the motor or reduces a rotational speed of the motor on condition that an abnormal impact detection unit detects the abnormal impact. A control unit controls activation of the protection unit differently when the rotational direction of the motor is set to a reverse rotational direction in comparison with when the rotational direction of the motor is set to a forward rotational direction.

摘要： 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.

摘要： 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.
