Abstract

The operating apparatuses of a washing machine and the methods on that are renovated. The afore-mentioned washing machine is including: a memory (7) that the reference signals are saved in order to operate a motor (5) in a best condition according to each of the condition of the torque and noise; a control unit (6) which generates the switching signals as calling the reference signals which are different each other according to the strokes of a washing machine, and comparing with the carrier signals; an inverter (4) which generates a motor operating signal as an external power is switched by a switching signal; a motor which is rotated by a motor operating signal; and a revolving screen of a washing machine which is operated by a motor.
