Abstract
Provided are an apparatus for and a driving method of driving a washing machine in which a washing tub is rotated by an inertial force in a freewheeling condition or at a low power driving mode, and a pulsator is reversely rotated, in a state where the pulsator and the washing tub are rotated in one direction. When driving the pulsator and the washing tub in the opposite directions, the inner rotor and the outer rotor are driven in a first direction where the washing tub is rotated, to then set the inner rotor to any one of a free-wheeling mode, an intermittent driving mode, and a low power driving mode, to thus rotate the washing tub, and the outer rotor is driven in one direction opposing the first direction to thus reversely rotate the pulsator.
