ABSTRACT:
A washing machine includes an electric motor developing torque used for wash, rinse and dehydration operations, a current detector detecting current flowing into the motor, and a torque controller performing a vector control for the motor on the basis of the current detected by the current detector so that the torque developed by the motor is optimum for at least each of the wash and dehydration operations.
