PURPOSE: A normal operation sensing method for a drum motor is provided to obtain information such as the rotation state, the operation state, the rotation speed of a motor which generates driving force, by detecting a driving current value to compare with a set current values. CONSTITUTION: A normal operation sensing method for a drum motor includes the steps of setting a driving current range of a drum motor when the operation of the drum motor is normal(110), driving the drum motor, detecting a driving current of the drum motor(120,140), and determining whether the detected value is in the set range to determine whether a current operation of the drum motor is normal(130,150,170). |
