Abstract:
A motor-driven appliance of one aspect of the present disclosure includes a motor and a controller. The controller includes a physical quantity detector, a variation deriving portion, a loaded condition detector, and driving output portion. The physical quantity detector detects a physical quantity related to an operating state of the motor. The variation deriving portion derives a variation in the physical quantity based upon the physical quantity detected by the physical quantity detector. The loaded condition detector detects that the motor is under a loaded condition in which the motor is applied with a load based upon the variation derived by the variation deriving portion. The driving output portion generates the driving output corresponding to whether the loaded condition is detected by the loaded condition detector.
