Abstract
A motor-driven appliance includes a motor and a control unit that controls a drive output to the motor. The control unit detects a state amount indicating an operational state of the motor to derive a fluctuation range of fluctuation in the state amount. The control unit detects whether the motor is in an unloaded state or in a loaded state, based on the derived fluctuation range to perform the drive output to the motor, based on the detected result.
