Abstract
A clothing treatment apparatus includes: a tub; a rotating tub; a pulsator; a washing shaft connected to the pulsator; a dehydrating shaft connected to the rotating tub; a clutch mechanism transmitting rotating force to the washing shaft and the dehydrating shaft; and a clutch driver operating the clutch mechanism. The clutch driver includes: a clutch motor; a cam interlocking the clutch mechanism; and a clutch motor driver having a control circuit driving the clutch motor. The clutch motor driver includes: a motor driving circuit driving the clutch motor while adjusting a driving direction and a driving speed of the clutch motor; a shunt resistor generating a phase current due to a voltage difference generated by the motor driving circuit; and a motor sensing controller that detects currents of the shunt resistor and determines whether the clutch mechanism and the clutch motor normally operate according to the detected current values.
