Abstract
A motor-driven apparatus comprises a motor, a heating subcircuit and a motor controlling subcircuit connected in parallel between two ends of an alternating current power supply. When the heating subcircuit operates, a power of the motor is adjusted according to an operating state of the heating subcircuit so that a total operation current flowing through a main line is less than a predetermined value.
