Motor drive apparatus for washing machine and driving method thereof

PURPOSE: A motor driving device for a laundry machine and a driving method thereof are provided to control the RPM and torque of the motor according to washing, rinsing, or spin mode by controlling the connection of U-phase stator coils, V-phase stator coils, and W-phase stator coils. CONSTITUTION: A motor control part (100) generates driving signals according to laundry control signals and generates connection control signals according to washing, rinsing, or spin mode. An inverter (120) switches DC power to AC power according to the driving signals. A brushless DC (BLDC) motor (130) for a laundry machine is driven by the AC power. A connection control part (140) controls the connection of multiple stator coils arranged in the BLDC motor according to the connection control signals.
