Abstract: A motor driven appliance comprises a battery, a motor, at least one switch, a control unit, an abnormality detection unit, a determination unit, and a processing unit. The at least one switch comprises an operation switch. The control unit controls driving of the motor by controlling power supply from the battery to the motor when the operation switch is turned on. The abnormality detection unit detects abnormality of the appliance. The determination unit determines whether the detected abnormality is a first type abnormality that can be cleared when the operation switch is switched from on to off, or is a second type abnormality that cannot be cleared even if the operation switch is merely switched from on to off. The processing unit is configured to perform a specific process when it is determined that the detected abnormality is the second type abnormality.

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: A hand-held electric power tool includes a main power SW provided in a motor housing, a trigger SW provided in a grip portion that protrudes from the motor housing, and a controller. The controller switches an operation mode to one of a drive enabled mode in which driving of the motor is enabled and a drive disabled mode in which driving of the motor is disabled, in accordance with a switching command from the main power SW. In the drive enabled mode, driving of the motor is controlled in accordance with a driving command input from the trigger SW. The controller switches the operation mode to the drive disabled mode in response to the driving of the motor being stopped due to stopping input of the drive command from the trigger SW.

Abstract: An electric work machine (2) includes a motor (M) and a control unit (36) that controls rotation of the motor. The control unit (36) is configured such that an operating mode is switchable between a normal mode, in which the motor is rotated within a prescribed output range, and a power mode, in which the motor is rotatable with energy greater than in the normal mode. Furthermore, the control unit (36) is configured to restrict use of the power mode.
