Abstract: The present disclosure relates to an electronic clutch-coupled motor assembly and a driving device for a washing machine having the same. The electronic clutch-coupled motor assembly includes a motor including a stator defining a space having a predetermined size at an inner center thereof and a rotor spaced a predetermined distance from an outer circumference of the stator, disposed to surround the stator and configured to rotate, and an electronic clutch including an electronic clutch insert core having a circular shape and an electronic clutch bobbin fixed and coupled to an inside of the electronic clutch insert core, and press-fitted and coupled to the stator through the space and integrated with the stator.
