Abstract: An electric power tool includes a motor with a rotor having a permanent magnet; a control unit that sets a control amount of the motor in accordance with operation of an operation portion and that drive-controls the motor based on the control amount; and a number-of-rotations detection unit that detects the number of rotations of the motor. During driving of the motor, when the number of rotations detected by the number-of-rotations detection unit has reached an upper limit number of rotations set in advance, the control unit shifts drive control of the motor to rotation control, in which the control amount is made to be increased or decreased so that the number of rotations of the motor becomes a predetermined target number of rotations.

Abstract: An electric power tool to tighten a screw while drilling a hole with the screw in a tightening-target-object includes a motor as a drive source. A motor control unit controls the motor such that the rotation number of the motor is a rotation number according to specifics of an operation input received by an operation receiving unit with a preset maximum rotation number as an upper limit. At a start-up of the motor, the maximum rotation number is set to a first maximum rotation number. When it is detected that a hole has been drilled in the tightening-target-object with the screw after the start-up of the motor, the maximum rotation number is set to a second maximum rotation number lower than the first maximum rotation number. The second maximum rotation number is set according to a material thickness so as to become lower as the material thickness is smaller.

Abstract: 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.

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: A power tool of one aspect for tightening a screw to a tightening-target-object is provided with a motor as a drive force. A motor controlling device controls the motor so as to make rotational frequency of the motor in accordance with an input operation received by an input-operation receiving unit. A first setting unit sets a maximum rotational frequency to a given first maximum rotational frequency when the motor is initiated. If the power tool clears a given condition for increasing rotational frequency after the motor is initiated, a second setting unit sets the maximum rotational frequency to a given second maximum rotational frequency that is larger than the first maximum rotational frequency.
