PURPOSE: An electric driving device is provided to improve torque by simultaneously rotating a rotation ring and a rotor. CONSTITUTION: A first driver(100) generates rotation power on the right and left in the same direction. A second driver(200) is rotated by the rotation power of the first driver. An electric power generator(300) transmits the rotation power of the second driver and generates electricity. A gear unit includes a first generation rotor which is rotatably received in a gear housing. A motor rotor passes through the right and left sides of a second motor housing. |
