Abstract

A motor driving apparatus for a washing machine, in which a motor is a washing machine motor with a double stator and a double rotor respectively having first and second U-phase, V-phase, and W-phase stator coils, includes: a motor controller for generating a drive signal in accordance with a washing mode, a rinsing mode and a dewatering mode; an inverter for generating a three-phase alternating-current (AC) power, in which any one-phase AC power of the three-phase AC power is applied in common to any one-phase stator coil of the first and second U-phase, V-phase, and W-phase stator coils for the washing machine motor; and a switching unit for switching to apply the remaining two-phase AC power of the three-phase AC power to any two-phase stator coils of the remaining two-phase stator coils of the first and second U-phase, V-phase, and W-phase stator coils for the washing machine motor.
